Africa Fighting Malaria claims to be fighting malaria

July 6, 2010

In response to earlier analysis here, that Africa Fighting Malaria (AFM) does not appear to do much to fight malaria, Richard Tren wrote a comment to a post at TropIKA.

Tren is unlikely to respond here; I gather he does not want to answer questions.

I will comment more completely later — I’m still not sure just what AFM does to fight malaria.  It’s humorous that he calls my question an “ad hominem” attack; I ask the questions because Tren has led the fight in the unholy smear campaign against Rachel Carson, against the U.S. Fish and Wildlife Service, against dozens of other scientists and science itself, against saving the bald eagle, against wise use of pesticides, against bed nets, against fighting malaria other than poisoning Africa. Most recently, as Tren mentions, he published a book that repeats much of the inaccurate claims and hoaxes he has relied on before.  But he’s concerned about attacks on him personally, and not the substance.

Why am I concerned at all?  The AFM-led assault on the World Health Organization, Rachel Carson, malaria fighters in public health, scientists and environmentalists  has come at an extremely high cost in human life. It is impossible to know how many people have died needlessly from malaria, yellow fever, leishmaniasis, dengue fever and other insect-borne diseases in the absence of medical care or prevention programs in lieu of DDT, but it must be millions — many of them could have been saved but for policy-makers’ beliefs that an increase in DDT could poison these people to health quickly and cheaply.  The campaign in favor of DDT has hampered serious efforts to fight malaria especially, such as Nothing But Nets and USAID’s support for prophylactic measures to beat the disease.

Does Tren answer the question well, what does AFM actually do to fight malaria?

Help me find some substance here in Tren’s letter (unedited by me in any way):

Paul,

It’s hard to know whether or not to respond to this. To say that we are ‘under fire’ because of the sniping and ad-hominem attacks from a blogger who has, for some or other reason, decided to take issue with my organization is an exaggeration to say the least. However even though your post has so far received zero comments I’d like to make a few things clear for the record.

AFM was founded in South Africa in 2000 and we opened an office in the United States in 2003. We maintain an office and a presence in South Africa as well as an office in the Washington DC. You say that we have focused most of our attention on one issue – the desirability of using DDT in mosquito control programs. Actually we focus on malaria control programs, not mosquito control programs; but to an extent you are correct. We have focused on this issue because DDT continues to play an important role in malaria control in many southern African programs (and in some other countries) and over the years other countries, such as Uganda have attempted to use DDT but have been harshly criticized and domestic and international groups forcing DDT spraying programs to close down. AFM defends DDT because of its outstanding record in saving lives and because it is under attack. The scare stories and smear campaigns against this insecticide are so pervasive and the misunderstanding about it so widespread that it is vital for some group or individual to provide a counterbalance, based on sound science.

AFM was a critical voice in securing an exemption for the use of DDT in the Stockholm Convention, and our research and advocacy work helped to usher in far-reaching reforms to US support for malaria control. We recently published a major book on DDT and its role in malaria control – The Excellent Powder – see http://www.excellentpowder.org. Additionally, we have responded to several recent publications that seek to limit the use of DDT (and interestingly other insecticides such as pyrethroids), with letters in Environmental Health Perspectives, British Journal of Urology International and working papers published on our own website. We have publicly exposed and criticized the way in which anti-insecticide advocacy groups, like Pesticide Action Network, have lobbied against indoor residual spraying programs that are funded and maintained by the President’s Malaria Initiative (PMI). All of these letters and papers can be accessed from our website – if any of your readers have any difficulty in accessing them, I’d be happy to forward them.

A word on our critical review of a paper published in British Journal of Urology International. Several researchers from the University of Pretoria published a paper in late 2009 claiming that DDT use in IRS would increase the chance that a boy would be born with a urogenital birth defect by around 33%. This paper was widely covered in the media and caused considerable problems for the malaria control programs in southern Africa. One scientist in particular even claimed on a public TV program that DDT was linked to the case of intersex South African athlete, Caster Semenya; this was further promoted in the print media causing great concern among people living in malaria areas. As we documented in our review, the research paper was very deeply flawed and the conclusions of the authors were premature to say the least. Although it required a considerable investment of time and effort, we respond with a formal review of both the paper and the outrageous claims made in the media for which there was no scientific evidence. Our letter to the journal, which was co-authored by some senior malaria scientists from South Africa, was published in the journal. Although the authors of the paper were given ample opportunity to respond to our criticisms, they declined – which is telling.

You make the point that we have focused on DDT – true, we have done so because there is a need for someone to respond to the never-ending claims of harm. Someone has to stand up and defend the malaria control programs that are using DDT and implementing effective malaria control measures – perhaps if some of the other advocacy groups or individuals stepped up and helped to defend IRS and the use of public health insecticides, we wouldn’t have to spend so much of our time and energy doing it.

In addition to defending the use of public health insecticides, we strongly advocate for investments in new insecticides and against regulations and policies that may hamper access to insecticides or investment in new insecticides. For instance in 2008/9 we coordinated a response to proposed EU regulation of insecticides that could limit access to insecticides. (The various documents that I describe are available on our website) As an example of our work in this regard, we recently held a successful policy briefing on Capitol Hill (in Washington, D.C.) involving stakeholders from advocacy groups, donor agencies and the private sector. Again details of this are available on our website.

Aside from our advocacy and defense of public health insecticides, we have been successful in exposing the ongoing use of sub-standard malaria medicines as well as fake medicines in Africa. Our research studies have been published in Malaria Journal, PLoS One, and other journals. In order to maintain this project and to get safe and effective malaria medicines out to communities we have raised funds for malaria treatments and have focused on increasing access in Uganda. Again, details are available on our website.

Lastly AFM is involved in a research and advocacy program to remove import tariffs and non-tariff barriers from malaria commodities. As malaria programs are scaled up, it is increasingly important to ensure that barriers to access are removed – import tariffs and non-tariff barriers can be significant and AFM is very excited to be involved in this important area of research and advocacy. See http://www.m-tap.org for more details.

So, I hope that this helps to answer the questions about what we do. We are a policy and research group, we have never pretended to be anything else and our track record stands for itself.

Paul, if you want to have a discussion about our work, I’d be happy to correspond with you and your colleagues on a basis of cordiality and respect. I would be delighted to debate our work on DDT, public health insecticides, drug quality and import tariffs and non-tariff barriers, but let’s leave the sniping bloggers and their misleading and biased comments out of this.

Malaria tough to beat: Canadian Press review of The Fever

July 5, 2010

At Canadian Press, Carl Hartman reviewed The Fever: How Malaria Has Ruled Humankind for 500,000 Years, a dramatic work of non-fiction about malaria and mosquitoes by Sonia Shah (Sarah Crichton Books/Farrar, Straus and Giroux 2010).  Hartman concluded:

Evidence of mosquito resistance to the drug has been recently reported.

Shah is skeptical of a surge of private charity that emphasizes the use of mosquito nets following the decline of government-led anti-malaria programs in the 1990s. Acknowledging the contributions of Bill Gates and former Presidents George W. Bush and Bill Clinton, she lists Veto the ‘Squito, a youth-led charity; Nothing but Nets, an anti-malarial basketball charity; and World Swim Against Malaria. She quotes The New York Times as decrying “hip ways to show you care.”

Her own comment: “Just because something is simple doesn’t necessarily mean that people will do it.”

“(T)he schools, roads, clinics, secure housing and good governance that enable regular prevention and prompt treatment must be built,” she concludes. “Otherwise the cycle of depression and resurgence will begin anew; malaria will win, as it always has.”

Anti-environmentalists, anti-scientists, and other conservatives won’t like the book:  It says we can’t beat malaria cheaply by just spreading a lot of poison on Africa and Africans.

Especially if you’re doing the noble thing and vacationing in the Gulf of Mexico in Alabama, or Mississippi, or Louisiana, you may want to read this.  If you’re vacationing in the Hamptons, Martha’s Vinyard, or Cannes, buy several copies to pass out at dinner with your friends.

Annals of DDT: Malawi ponders DDT use against malaria

June 21, 2010

Here’s a news story that Richard Tren and Donald North hope neither you nor anyone else will read.  It says that Malawi is pondering whether to use DDT for Indoor Residual Spraying (IRS) to fight malaria this season — and it lists several other nations that use DDT in exactly that way.

Why do the Chronically Obsessed With Rachel Carson (COWRC) like Tren and North hope you won’t see it?

It says DDT is being used broadly against malaria, in several nations on two continents.  That directly contradicts one of their favorite claims, that environmentalists (always unnamed) prevent the use of DDT anywhere.  It also shows clearly that DDT is not banned in Africa, another claim they like to blame on unnamed environmentalists and “left” do-gooders.

Facts of the malaria fight are that the consensus among serious malaria-warriors favors the integrated pest management schemes Rachel Carson wrote would be the savior of pesticides, in 1962 (in international circles, it’s called integrated vector management, “vectors” being the carriers of disease).  Quite to the contrary of Rachel Carson’s being the cause of needless deaths to malaria, her methods are saving lives.  The death toll from malaria is lower now than it was when DDT was used more broadly, and used outdoors.

Malawi going for DDT to fight malaria

Nyasa Times, June 20, 2010

Malawi is contemplating to start using DDT, an organochlorine pesticide, as a precaution in the fight against malaria in the country.

Chris Kang'ombe, Malawi Secretary for Health - Nyasa Times

Chris Kang'ombe, Malawi Secretary for Health - Nyasa Times

Principal Secretary in the Ministry of Health Chris Kang’ombe (pictured) said in Lilongwe during the launch of this year’s anti-malaria campaign themed, “Malungo zii (Kick out malaria)”.

“We know that our friends from Zambia and other countries are using it as an indoor residual spraying and it is working, so we are looking into it if we can do the same,” said Kang’ombe.

According to 2004-2009 statistical data provided by the UN, World Bank, WHO and UNAIDS, there were 4,204,468 reported malaria cases, 12,950 estimated malaria deaths and 7,132 reported malaria deaths in Malawi.

“We sent a team to Zambia to do a research on the use of DDT in fighting malaria and once the recommendations are made we will see what to do. We know that they are successful but we have to look at what effects DDT has on environment and agriculture taking into consideration that our economy is agro-based,” he said.

Some commentators and activists have raised concerns about DDT contaminating the environment if it is used in vector control. As with the other insecticides used in IRS, DDT causes minimal or zero contamination of the wider environment. Because DDT does not escape into the wider environment, it poses little or no threat to wildlife.

Results from the 2008 MIS demonstrated the dramatic progress Zambia is making in its fight to control malaria. Since 2006, malaria parasite prevalence in children has been reduced by 50%, and moderate to severe anemia has been reduced by more than 60%.

DDT is not only highly effective in malaria control, but it is also significantly cheaper than the other insecticides that are suitable for indoor residual spraying (IRS). It is easy to use and safe for both the residents of houses sprayed and the sprayers themselves.

More people than ever are sleeping under bed nets and two-thirds of all households are protected by at least one ITN or indoor residual spraying.

Use of DDT to fight malaria has been increasing since it was endorsed in 2006 by the World Health Organization and the President’s Malaria Initiative (PMI), a U.S. aid program launched by former President Bush.

USAID provides approximately $26 million per year to Malawi under PMI to purchase and distribute about 1,600,000 long life insecticide-treated bed nets, according to its Malawi office fact sheet.

“It is also used to purchase and distribute a national supply of over 6.6 million doses of life saving artemisinin-based combination therapy (ACT) drugs, implement an Indoor Residual Spraying (IRS) programme for 28,000 households and provide preventive treatment for malaria nationwide for pregnant women attending antenatal care,” reads part of the report.

PMI activities began in Malawi in 2007 and the U.S. government has committed a total of $107 million for addressing malaria over the five year period of 2007-2012.

“With six million cases of malaria per year in Malawi, the fight against malaria is far from over but through close collaborations between the governments of the United States and Malawi and other partners, we are making progress,” said Curt Reintsma, USAID Mission Director.

In 2009, data showed that use of ITNs by vulnerable children improved to 61% from 37% in 2005.

“We rededicate our partnership between Malawi and the United States to defeat this preventable and treatable killer,” said Reintsma.

Kang’ombe said the ministry has been implementing several malaria control strategies aimed at reducing the burden of malaria to a level of no public health significance in Malawi. These strategic areas which are coordinated by the NMCP includes; Malaria Case Management, Intermittent Preventive Treatment for pregnant women (IPTp) where women are routinely provided with at least 2 doses of SP during pregnancy.

“Integrated Vector Management is another major strategy that the ministry of health is implementing as one of the control measures for malaria in Malawi. This involves distribution of Insecticide Treated Mosquito nets and Indoor Residual Spraying. Operational Research, Monitoring and Evaluation and Information, Education and Communication/Advocacy are some of the cross cutting strategic areas that are also being implemented,” said Kang’ombe adding.

Some nations which are using DDT are: Ethiopia, South Africa, India, Mauritius, Myanmar, Yemen, Uganda, Mozambique and Swaziland, Zimbabwe, North Korea, Eritrea, Gambia, Namibia and Zambia.

DDT may have a variety of human health effects, including reduced fertility, genital birth defects, breast cancer, diabetes and damage to developing brains. Its metabolite, DDE and can block male hormones.

French researchers find link between DDT exposure and Parkinson’s Disease

June 16, 2010

French researchers looked at men who possess a gene that predisposes them to Parkinson’s Disease, and found that DDT exposure correlates with actual onset of the disease.

(Reuters) – Men with certain genetic variations who were exposed to some toxic pesticides which are now largely banned run an increased risk of developing Parkinson’s disease, French scientists said Monday.

Researchers found that among men exposed to pesticides such as DDT, carriers of the gene variants were three and a half times more likely to develop Parkinson’s than those with the normal version of the gene.

The scientists, whose work was published in the Archives of Neurology journal, think the brains of people with the gene variant fail to flush out toxins as efficiently as those with normal versions of the gene, suggesting environmental as well as genetic factors are important in the risk of Parkinson’s.

DDT, which belongs to a group of pesticides known as organochlorines, is one of the “Dirty Dozen” chemicals banned by a 2001 United Nations convention after it was found to be a toxin that can suppress the immune system.

It is infamous for threatening bird populations by thinning eggshells, and has also been linked to increase risks in humans of diseases such as cancer and Parkinson’s — an incurable and often deadly brain disease.

But exemptions to the DDT ban are allowed in many developing nations because it so effective in killing mosquitoes. DDT’s Swiss inventor Paul Hermann Muller won the 1948 Nobel Prize for Medicine — before its wider toxic effects were known.

Alexis Elbaz and Fabien Dutheil, of France’s National Institute for Health and Medical Research (INSERM) studied 101 men with Parkinson’s and 234 without the disease to look at links between organochlorine exposure and Parkinson’s disease.

The study included only men, and all of them had had high levels of exposure to pesticides through their work as farmers.

The scientists found the link was around 3.5 times stronger in men who carried two copies of a gene known as ABCB1, which plays a role in helping the brain flush out dangerous chemicals.

File that one away for the next time some yahoo claims there are no harmful effects to health from DDT.  The study probably could not distinguish between heavy exposure to pesticides and the much lighter exposure assumed to result from Indoor Residual Spraying of DDT, such as is used in some places in Africa in the fight against malaria.

Anybody got a copy of the actual study, in English?


Fighting malaria: Bed nets crucial

Does Africa Fighting Malaria actually fight malaria?

June 11, 2010

This spring’s publication of a book, The Excellent Powder, by Richard Tren and Donald Roberts, repeating most of the false claims about malaria and DDT, got me wondering. Their organization, Africa Fighting Malaria (AFM):

Does AFM do anything to fight malaria? At its own website it makes some astoundingly grandiose claims:

In its seven years of operation, AFM has helped transform malaria control by taking on and turning around failing public health institutions, donor agencies and governments.

Offhand I can’t think of any public health institution AFM has even been involved with, other than its undeserved criticism of the World Health Organization — and if anyone knows of any donor agency or government AFM has “turned around,” the history books await your telling the story.

Africa Fighting Malaria springs to life every year around World Malaria Day, April 25, with editorials claiming environmentalists have killed millions. AFM seems to be one of the sources of the bizarre and false claim that Rachel Carson is a “mass murderer.” AFM makes noise whenever there is difficulty getting a DDT spraying campaign underway in any part of Africa, for any reason, quick to lay the blame on environmentalists, even though the blame generally rests in other places. AFM is quick on the draw to try to discredit all research into DDT that suggests it poses any health threat, though so far as I can tell AFM has published no counter research, nor has it conducted any research of its own.

In its 2009 Annual Report, AFM proudly states “AFM is the only advocacy group that routinely supports IRS [Indoor Residual Spraying] and through its advocacy work defends the use of DDT for malaria control.”

Cleverly, and tellingly, they do not reveal that IRS in integrated vector (pest) management is what Rachel Carson advocated in 1962, nor do they mention that it is also supported by the much larger WHO, several nations in Africa, and the Gates Foundation, all of whom probably do more to fight malaria when they sneeze that AFM does intentionally.

Google and Bing searches turn up no projects the organization actually conducts to provide bed nets, or DDT, or anything else, to anyone working against malaria. I can’t find any place anyone other than AFM describes any activities of the group.

AFM has impressive video ads urging contributions, but the videos fail to mention that nothing in the ad is paid for by AFM, including especially the guy carrying the pesticide sprayer.

Looking at the IRS Form 990s for the organization from 2003 through 2008 (which is organized in both the U.S. and South Africa), it seems to me that the major purpose of AFM is to pay Roger Bate about $100,000 a year for part of the time, and pay Richard Tren more than $80,000 a year for the rest of the time.

Can anyone tell me, what has Africa Fighting Malaria ever done to seriously fight malaria? One could make the argument that if you sent $10 to Nothing But Nets, you’ve saved more lives than the last $1 million invested in AFM, and more to save lives than AFM in its existence.

Tip of the old scrub brush to Pharyngula and Antievolution.org, even though AFM wasn’t what they were targeting.

Update: Tim Lambert at Deltoid sent some traffic this way, which caught the attention of Eli Rabett, which reminded me that there really is more to this story about Africa Fighting Malaria, and you ought to read it at Deltoid and Rabett’s warren.

Washington Times felled by DDT poisoning

June 9, 2010

Washington Times‘ owner, the Unification Church, put the paper up for sale earlier this year — tired of losing north of $30 million a year on the thing.  It appears that, in a cost-cutting move, the paper has laid off all its fact checkers and most of its editors.

And anyone with a brain.

DDT use in the U.S. peaked in 1959, with 70 million pounds of the stuff used in that year.  This ad comes from about that time.

DDT use in the U.S. peaked in 1959, with 70 million pounds of the stuff used in that year. This ad for a French product containing DDT comes from about that time.

How do we know?

Our old friend Stephen Milloy complains about Time Magazine’s “50 Worst Inventions” list, including, especially the listing of DDT, as discussed earlier.  It’s wrong, and silly.  Good fact checkers, and good editors, wouldn’t let such claptrap make it into print.

Milloy packed an astounding number of whoppers in a short paragraph about DDT:

From 1943 through its banning by the EPA in 1972, DDT saved hundreds of millions of lives all over the world from a variety of vector-borne diseases. Even when Environmental Protection Agency Administrator (and closeted environmental activist) William D. Ruckelshaus banned DDT in 1972, he did so despite a finding from an EPA administrative law judge who, after seven months and 9,000 pages of testimony, ruled that DDT presented no threat of harm to humans or wildlife. Today, a million children die every year from malaria. DDT could safely make a tremendous dent in that toll.

Let us count the errors and falsehoods:

1.  DDT was used against typhus from 1943 through about 1946, and against bedbugs; it saved millions, but not hundreds of millions. Death tolls from typhus rarely rose over a million a year, if it ever did.  Bedbugs don’t kill, they just itch.  If we add in malaria after 1946, in a few years we push to four million deaths total from insect-borne diseases — but of course, that’s with DDT being used.  If we charitably claim DDT saved four million lives a year between 1943 and 1972, we get a total of 117 million lives saved.  But we know that figure is inflated a lot.

Sure, DDT helped stop some disease epidemics.  But it didn’t save “hundreds of millions of lives” in 29 years of use.  The National Academy of Sciences, in a book noting that DDT should be banned because its dangers far outweigh its long-term benefits, goofed and said DDT had saved 500 million lives from malaria, and said DDT is one of the most beneficial chemicals ever devised by humans.  500 million is the annual infection rate from malaria, with a high of nearly four million deaths, but in most years under a million deaths.  Malaria kills about one of every 500 people infected in a year.  That’s far too many deaths, but it’s not as many lives saved as Milloy claims.

NAS grossly overstated the benefits of DDT, and still called for it to be banned.

The question is, why is Milloy grossly inflating his figures?  Isn’t it good enough for DDT to be recognized as one of the most beneficial substances ever devised?

My father always warned that when advertisers start inflating their claims, they are trying to hide something nasty.

2.  Ruckelshaus didn’t ban DDT on his own — nor was he a “closeted” environmentalist. He got the job at EPA because he was an outstanding lawyer and administrator, with deep understanding of environmental issues — his environmentalism was one of his chief qualifications for the job.  (Maybe Milloy spent the ’70s in a closet, and assumes everyone else did, too?)  But EPA acted only when ordered to act by two different federal courts (Judge David Bazelon ordered an end to all use of DDT at one of the trials).  At trial, DDT had been found to be inherently dangerous and uncontrollable.  Both courts were ready to order DDT banned completely, but stayed those orders pending EPA’s regulatory hearings and action.

In fact, regulatory actions against DDT began in the 1950s; by 1970, scientific evidence was overwhelming (and it has not be contradicted:

The U.S. Department of Agriculture, the federal agency with responsibility of regulating pesticides before the formation of the U.S. Environmental Protection Agency in 1970, began regulatory actions in the late 1950s and 1960s to prohibit many of DDT’s uses because of mounting evidence of the pesticide’s declining benefits and environmental and toxicological effects. Rachel Carson’s book Silent Spring in 1962 stimulated widespread public concern over the dangers of improper pesticide use and the need for better pesticide controls.

In 1972, EPA issued a cancellation order for DDT based on adverse environmental effects of its use, such as those to wildlife, as well as DDT’s potential human health risks. Since then, studies have continued, and a causal relationship between DDT exposure and reproductive effects is suspected. Today, DDT is classified as a probable human carcinogen by U.S. and international authorities. This classification is based on animal studies in which some animals developed liver tumors.

DDT is known to be very persistent in the environment, will accumulate in fatty tissues, and can travel long distances in the upper atmosphere. Since the use of DDT was discontinued in the United States, its concentration in the environment and animals has decreased, but because of its persistence, residues of concern from historical use still remain.

3.  Judge Sweeney ruled that DDT is dangerous to humans and especially wildlife, but that DDT’s new, Rachel-Carson-friendly label would probably protect human health and the environment. EPA Administrative Law Judge Edmund Sweeney presided at the hearings in 1971.  As in the two previous federal court trials, DDT advocates had ample opportunity to make their case.  32 companies and agencies defended the use of DDT in the proceeding.  Just prior to the hearings, DDT manufacturers announced plans to relabel DDT for use only in small amounts, against disease, or in emergencies, and not in broadcast spraying ever.  This proved significant later.

Judge Sweeney did not find that DDT is harmless.  Quite to the contrary, Sweeney wrote in the findings of the hearing:

20.  DDT can have a deleterious effect on freshwater fish and estuarine organisms when directly applied to the water.

21.  DDT is used as a rodenticide. [DDT was used to kill bats in homes and office buildings; this was so effective that, coupled with accidental dosing of bats from their eating insects carrying DDT,  it actually threatened to wipe out some species of bat in the southwest U.S.]

22.  DDT can have an adverse effect on beneficial animals.

23.  DDT is concentrated in organisms and can be transferred through food chains.

DDT use in the U.S. had dropped from a 1959 high of 79 million pounds, to just 12 million pounds by 1972.  Hazards from DDT use prompted federal agencies such as the Department of Agriculture and Department of Interior to severely restrict or stop use of the stuff prior to 1963.  Seeing the writing on the wall, manufacturers tried to keep DDT on the market by labeling it very restrictively.  That would allow people to buy it legally,  and then use it illegally, but such misuse can almost never be prosecuted.

Sweeney wrote that, under the new, very restrictive label, DDT could be kept on the market.  Ruckelshaus ruled that EPA had a duty to protect the environment even from abusive, off-label use, and issued a ban on all agricultural use.

4.  More DDT today won’t significantly reduce malaria’s death toll. Milloy fails to mention that DDT use against malaria was slowed dramatically in the mid-1960s — seven years before the U.S. banned spraying cotton with it — because mosquitoes had become resistant and immune to DDT.  DDT use was not stopped because of the U.S. ban on spraying crops; DDT use was reduced because it didn’t work.

Milloy also ignores the fact that DDT is being used today.  Not all populations of mosquitoes developed immunity, yet.  DDT has a place in a carefully-managed program of “integrated vector management,” involving rotating several pesticides to ensure mosquitoes don’t evolve immunity, and spraying small amounts of the pesticide on the walls of houses where it is most effective, and ensuring that DDT especially does not get outdoors.

To the extent DDT can be used effectively, it is being used.  More DDT can only cause environmental harm, and perhaps harm to human health.

Most significantly, Milloy grossly overstates the effectiveness of DDT.  Deaths from malaria numbered nearly 3 million a year in the late 1950s; by the middle 1960s, the death rate hovered near 2 million per year.  Today, annual death rates are under a million — less than half the death rate when DDT use was at its peak.  Were DDT the panacea Milloy claims, shouldn’t the death numbers go the other way?

Milloy gets away making wild, misleading and inaccurate claims when editors don’t bother to read his stuff, and they don’t bother to ask “does this make sense?”  Nothing Milloy claims could be confirmed with a search of PubMed, the most easily accessible, authoritative data base of serious science journals dealing with health.

Obviously, Washington Times didn’t bother to check.  Were all the fact checkers let go?

Even more lunatic

Milloy also attacked the decision to get lead out of gasoline.  Ignoring all the facts and the astoundingly long history of severe health effects from lead pollution, Milloy dropped this stinking mental turd:

As to leaded gasoline, we can safely say that leaded gasoline helped provide America and the world with unprecedented freedom and fueled tremendous prosperity. We don’t use leaded gasoline in the United States anymore, but more because people simply don’t like the idea of leaded gasoline as opposed to any body of science showing that it caused anybody any harm. It’s the dose that makes the poison, and there never was enough lead in the ambient environment to threaten health.

The U.S. found that getting lead out of gasoline actually improved our national IQ.  Lead’s health effects were so pervasive, there was an almost-immediate improvement in health for the entire nation, especially children, when lead was removed.  Denying the harms of tetraethyl lead in gasoline goes past junk science, to outright falsehood.

What is Milloy’s fascination with presenting deadly poisons as “harmless?”  Why does he hate children so?

Why do publications not catch these hallucination-like errors and junk science promotions when he writes them?

Measles ride again

May 23, 2010

Those people who warn against vaccinating kids?  They are laying low today.  They didn’t pick up the New York Times as they usually do on a Sunday — they don’t want to know.

You may want to know, however.

More than 1,100 deaths from measles have been reported among 64,000 known cases in Africa the last year, it said. Chad, Nigeria and Zimbabwe have had the largest outbreaks.

“There is a widespread resurgence of measles with these outbreaks in over 30 African countries, some of which are seeing very high case fatality ratios,” WHO expert Peter Strebel told a news briefing.

Some 8,000 migrant children in Bulgaria also had the highly-contagious disease during the period, he said.

Measles deaths among children under five years old fell to 118,000 in 2008 from 733,000 in 2000, according to the United Nations agency’s latest figures.

But the WHO warned that a lack of funding and political commitment could result in a return to more than 500,000 cases measles deaths per year by 2012, wiping out the gains to date.

Avoiding vaccinations for measles suddenly may not be a great idea.


Wall Street Journal’s DDT-fueled war on science

May 12, 2010

I don’t subscribe to the Wall Street Journal — their discounts to educators are lousy.

So I missed this editorial when it ran on April 24, 2010 (page A12), “DDT and population control – malaria still kills one million every year.”

Nominally, that should be good news.  At the peak of DDT use in the early 1960s, malaria killed about 3 million people annually.  By the time we banned DDT use on cotton crops in the U.S., the death toll was still about 2 million people annually.  From the heyday of DDT, we’ve decreased malaria’s death toll, to less than half what it was.

Editorial writers at the Journal don’t let facts get in their way when they go off on a misdirected political jihad or crusade.  Gross error Number 1:  They mislead readers about the facts.

They are claiming that a million is too many (it is), but they claim that the total would be significantly less if only Americans would attack Africa with poison.  We have trouble enough with wars in Afghanistan and Iraq, it seems to me.  There is no indication that we could reduce malaria rates with a lot of extra poison.  Malaria is a parasite in human blood.  To defeat the disease we have to defeat the infections in humans.  Mosquitoes just spread the disease from one human to another.  DDT does not cure malaria in humans; it is one preventive device of limited effectiveness.

What are they on about?

The Journal’s editorial writers said:

Environmental activists this week marked the 40th anniversary of Earth Day, which happened to fall three days before World Malaria Day. Insofar as Earth Day politics have contributed to today’s malaria epidemic, the two events are related.

You could see this one coming.  The reactionaries at the editorial seek out opportunities to criticize environmentalists, whose cause they see as anti-business.   The Journal’s editorial page usually carries an op-ed piece by Hoover Institute maven Henry I. Miller about once a year (see here, for example), claiming we need DDT to fight West Nile virus.  We don’t, of course.  West Nile virus-carrying mosquitoes are best fought with other pesticides, when pesticides are used.  They need to be hit before adulthood, while they are still larva, in the water.  DDT is exactly wrong for such applications.  But Miller’s piece comes around almost every year, as soon as the first West Nile virus infections in humans are noted.

So, since they so soundly disregard science on that diatribe, why not here, too?  DDT offers a great target for Tea Baggers, Know-Nothings, and truth bashers.  Most of the history of DDT was written before the internet, so it’s easier to spread falsehoods without contradiction.

Disinformation.  Propaganda.  Shame on the Wall Street Journal.

Earth Day and World Malaria Day are related in this way:  Environmentalists warned us that doing the wrong stuff in the environment would make it harder to fight malaria, and they were right.  People who resist clean air and clean water legislation also resist legislation to stop poisoning our planet.  Those people rarely do anything to fight malaria, either.  Human comfort, human health, human survival, is not what they are concerned about.

Earth Day founder Gaylord Nelson, a U.S. Senator from Wisconsin, was a leading opponent of the insecticide DDT, which remains the cheapest and most effective way to combat malarial mosquitoes.

Gaylord Nelson, the father of Earth Day, was governor of Wisconsin when the University of Wisconsin did the first studies showing that songbirds and raptors in Wisconsin were being wiped out by DDT. We should expect him to be an opponent of indiscriminate use of the stuff.  His state was on the road to ruin, and long before the federal government acted against DDT, Wisconsin had laws and regulations to limit its use.  Wisconsin’s wild populations recovered a bit more quickly because Wisconsin had acted.

Nelson also knew that, in the U.S., malaria was conquered by 1939 (according to the Centers for Disease Control).  DDT came along in 1946, seven years later.  While DDT was used to control mosquitoes in the U.S., it was for no disease control reasons — that was why so many people opposed the rather pointless use of the stuff.  And I suspect Nelson was savvy enough to know that DDT has not been the cheapest means of controlling mosquitoes for several years.  One application of DDT in Africa costs about $12.00, for the professional who must apply it, and the testing to determine whether DDT will even work.  One application lasts about six months.  So, for a year’s protection, DDT costs about $24.00 per house, per year.

Bednets cost about $10.00, and last about five years.  That works out to $2.00 year.  For $24.00, you could provide a dozen different nets in a home, though most homes would use them only to protect children.

Moreover, recent test runs in Africa show DDT about 25% to 50% effective in reducing malaria incidence, while bednets are about 50% to 85% effective.  Nets are cheaper and more effective.

Doesn’t the Wall Street Journal have fact checkers?  Or do they just not care about the facts?

Rachel Carson’s 1962 book, “Silent Spring,” misleadingly linked pesticides to cancer and is generally credited with popularizing environmental awareness.

Wrong on three fronts.  Carson noted that the family of chemicals from which DDT comes might have links to cancer, but she did not make the claim that DDT is carcinogenic.  DDT was banned because it’s a long-term, deadly poison that destroys ecosystems.  Cancer in humans was not a part of the equation.

However, DDT is now known to be a weak human carcinogen.  Every cancer-fighting agency on Earth lists it as a “probable human carcinogen” (it is confirmed to cause cancer in other mammals).  Can’t the Wall Street Journal find the phone number of the American Cancer Society?

DDT earned its ban because of 20 years of research data by 1972, showing that DDT kills virtually everything it comes in contact with that is smaller than a large man, and it destroys ecosystems.  Talking about DDT’s carcinogenicity is a red herring.  Carson didn’t claim DDT was a significant cause of cancer, nor was DDT banned from agricultural use because anyone thought it was a significant cause of cancer.  Yes, DDT is a weak human carcinogen, contrary to the Journal’s implication; but no, that’s not why it was banned.

Carson’s book certainly ignited concerns about human activities affecting environment other than land development.  But “environmental awareness” is as old as our nation, at least.  A hundred years prior to Rachel Carson’s book, the U.S. set aside the world’s first National Park, Yellowstone.  60 years earlier, Teddy Roosevelt and Gifford Pinchot led the drive to conserve the nation’s forests.  The Soil Conservation Service, a New Deal program, worked to save soil on farms and unimproved areas, a good 30 years before Carson’s book.  Environmental awareness is an almost-congenital trait in Americans.  Rachel Carson sounded alarms about new reactive chemical combinations.  Americans were already alert to the need to save soil, water, air and wild spaces.

We banned DDT to save our crops and to save our wildlife.  Those are good reasons to keep the ban today.

But other leading greens of the period, including Nelson, biologist Paul Ehrlich and ecologist Garrett Hardin, were also animated by a belief that growth in human populations was harming the environment.

Nelson thought the U.S. needed to slow immigration (see more below).  Ehrlich feared a massive round of starvation, which was staved off only with the Green Revolution and billions of dollars of foreign aid money, the good luck of our having Norman Borlaug and the Rockefeller Foundation, and major economic change in nation’s like India and China.  Hardin pointed out that even the best intentioned people needed a structure to encourage them to conserve, else conservation would not take place.

They all recognized that while any human could minimize her impact on the natural world, no one person could ameliorate all the effects of billions of people.

“The same powerful forces which create the crisis of air pollution also are threatening our freshwater resources, our woods, our wildlife,” said Nelson. “These forces are the rapid increase in population, industrialization, urbanization and scientific technology.”

Notice, please, that Sen. Nelson did not suggest humans should do anything to cause or encourage massive human death (nor did the Journal do the courtesy of noting where they quoted him from).  He merely notes that air pollution and water pollution, and a lack of freshwater, are created by human populations, industry, urban sprawl and technology.  All of these things threaten human health.  Nelson is concerned that we not add to human illness and misery.  That’s not what the Journal’s editorial wants you to think, however.  It will suggest instead that Nelson urged more human suffering and death.

How craven must an editorial board be to accuse good people, falsely, of such sins?

In his book “The Population Bomb,” Mr. Ehrlich criticized DDT for being too effective in reducing death rates and thus contributing to “overpopulation.”

I doubt it.  I can’t find anything quite to that description in my copy of the book.  It’s a common internet legend (one level dumber than urban legend) — but shouldn’t the Wall Street Journal have higher standards than to use for documentation, “my cousin Clem heard a story about a person his aunt once knew?”

Hardin opposed spraying pesticides in the Third World because “every life saved this year in a poor country diminishes the quality of life for subsequent generations.”

Now the Journal is making things up.  In the essay from which the Journal quotes him, Hardin wrote about the dangers of uncontrolled immigration and population growth — almost sounding like an angry Arizona Tea Partier at times — but never did he get close to suggesting that we should not suppress malaria, for any reason.  (Wise readers may wish to see what Hardin actually said, where he really went awry if he did, and how his words resonate today, at his essay, “Living on a Lifeboat.”  Writers at the Journal should be ashamed of savaging the reputation of a guy who is so much in tune with what they usually write.  Notice Hardin does not mention DDT, use of pesticides in foreign nations, malaria, nor any other disease.  He rails at starvation, however.)  When the Wall Street Journal engages in fiction, shouldn’t they let us know?

For these activists, malaria was nature’s way of controlling population growth, and DDT got in the way.

Gee, in context, that’s all fiction. Never did Sen. Gaylord Nelson claim malaria was a good population control tactic, nor that we should stop using DDT to allow more people to die. Those are whole cloth lies. Never did Garrett Hardin say either of those things. Never did Paul Ehrlich say those things.

For anti-science activists, like the writers at the Wall Street Journal’s editorial page, falsehoods have become coin of the realm, and DDT is just one more sciency thing to try to use as whip against political opponents. The serious question is, why is the Wall Street Journal opposed to clean air and clean water?  Why are they trying to politicize things at all?

The writers at the Journal continue:

Today, malaria still claims about one million lives every year—mostly women and children in sub-Saharan Africa. There’s no evidence that spraying the chemical inside homes in the amounts needed to combat the disease harms humans, animals or the environment. Yet DDT remains severely underutilized in the fight against malaria because the intellectual descendants of Senator Nelson continue to hold sway at the World Health Organization and other United Nations agencies.

Full disclosure would be good here.  Malaria death rates are at the lowest point in history, at least since 1900.  Yes, too many die — but it’s not the fault of “not enough DDT.”  No nation that uses DDT has ever succeeded in eradicating malaria with pesticides alone.  Only those nations that assaulted malaria from the  human side, treating malaria in human victims, have been successful in eradicating the disease.  DDT use was essentially suspended in Africa by the World Health Organization in about 1965, because overuse of DDT in agriculture had bred mosquitoes that are resistant and immune to the stuff.  No amount of DDT spraying, anywhere, can reverse that.  Spraying DDT where mosquitoes are unaffected by it, is stupid.

Plus, studies indicate a correlation between DDT use, even in those small amounts, and premature deaths to children in the households sprayed.  DDT is not harmless.  DDT is not benign.

DDT has never been banned in Africa, and even under the 2001 Persistent Organic Pesticides Treaty (POPs) DDT has a special carve out to keep it available to fight malaria, despite its being a destroyer of worlds.  So implicit in the Journal’s screed here is that Africans are too stupid or lazy to use a substance that would save their children and themselves from malaria, though it’s available relatively cheaply.

Is DDT “underutilized?”  Again we should ask, why would anyone use DDT where it is not effective? Then we should ask, who would use DDT in fighting disease in Africa, and do they use it?  It turns out that DDT is not completely superfluous to all mosquito populations.  But testing is required to be sure DDT will work — were an organization to use ineffective pesticides, thousands could die, and the testing is therefore a preservation of human life.  And, because of past incidents in Africa, for example when DDT killed off the fish local populations depend on for their food, DDT use is extremely limited, to indoor applications only, and only by trained professionals who limit its spread.

WHO has been using DDT in Africa for indoor residual spraying (IRS) since the 1950s.  Use was slowed when DDT’s effectiveness was compromised.  In recent years WHO held a press conference on DDT to encourage locals who fear DDT poisoning to go along, and since 2005 DDT’s effectiveness appears to be dropping.  But DDT is available for use wherever it is needed to fight malaria in Africa.

Is the Wall Street Journal calling for mass poisoning of Africa?  What else could they be talking about?  Why would they call for such a thing?

The Journal claims WHO and other UN agencies are “under the sway” of Sen. Nelson, and that’s bad?  Let’s be clear:  Nelson didn’t oppose use of DDT in Africa to fight malaria.  UN’s WHO is the leading continent-wide advocate of proper use of DDT to fight malaria.  If the Journal claims that current, appropriate use of DDT is too little, what is the Journal advocating?

The good news is that the Obama Administration has continued the Bush policy of supporting DDT spraying in Zambia, Mozambique and other countries where the locals want it used. “Groups like the Pesticide Action Network have lobbied the U.S. Agency for International Development to stop spraying DDT, and Obama is ignoring them so far,” says Richard Tren of Africa Fighting Malaria, an advocacy group. “They’re prioritizing what makes sense from a science and public health point of view.”

Let’s be clear:  The Bush administration refused to allow U.S. money to be used to purchase DDT, or to use DDT, until about 2005.  Environmental Defense, the organization that first sued to stop DDT use in the U.S., argued for years that DDT should be allowed in the limited use WHO proposed, but Bush’s people stood firmly opposed, though never explaining why.  In any African nation where local people want DDT, it’s freely available with other money, of course.  So U.S. opposition, bizarre as it was, was not and is not a barrier to DDT use.

Most environmental groups favor beating malaria, and if a bit of DDT carefully controlled will help do the trick, so much the better.  While business lobbyists have falsely impugned environmentalists for years on this point, actual opposition to DDT use has come, in Uganda for example, from business groups.  Tobacco growers claim they fear some DDT will somehow get on tobacco leaves, and that will make the stuff unsaleable in the European Union.  Cotton growers fear any faint traces of DDT will ruin sales of organic cotton to the EU.  These business groups sued to stop DDT use against malaria in Uganda.

But environmental organizations, like ED, the Sierra Club, and others, have been fighting malaria for 40 years.

Which is more than we can say for Richard Tren.  Tren is one of two or three of the leading false propagandists for poisoning Africa in the world.  He tells false tales about Rachel Carson, false tales about DDT’s harms and effectiveness, and as best I can tell he has never lifted one finger or written one check to fight malaria himself, while taking tens of thousands of dollars to spread his false tales.

There are dozens of noble malaria fighters out there whose opinions we should seek — Socrates Litsios, the late Fred Soper, to mention two.  Why does the formerly august Wall Street Journal use Richard Tren as a source, when there are authoritative people handy to talk?

DDT helped to eradicate malaria in the U.S. and Europe after World War II, and the U.S. is right to take the lead in reforming public health insecticide policy and putting the lives of the world’s poor above green ideology.

Printed in The Wall Street Journal, page A12

According to the history of malaria at the CDC, malaria was essentially wiped out in the U.S. by 1939.  DDT was not available for use for another seven years.  Malaria was gone from northern Europe by World War II.  DDT was a tool in the final eradication of the disease in Italy and Greece.  But the main campaign against malaria was in curing the disease in humans, before the mosquito populations could rise up.

Among the nasty facts of science the Journal either does not know, or refuses to say, DDT can’t eradicate mosquitoes.  In anti-malaria campaigns, DDT is used to knock down the mosquito populations temporarily, so that the disease can be cured in humans.  Mosquito populations will quickly rise again, and in even greater numbers — but if there is no human reservoir of malaria parasites for mosquitoes to draw from, they cannot spread the disease.  Malaria parasites must spend part of their life cycle in humans, and part in mosquitoes.

Curing malaria in humans is the tough part.  It requires money to improve medical care, for accurate and speedy diagnoses, and for prompt and complete treatment of the disease in each patient.  Preventing malaria is aided greatly by better-built homes with screens on windows, the sort of stuff that requires people to have more than subsistence incomes.  So beating malaria generally requires economic development, too.

How much easier is it to bash environmentalists than to confront the real causes of malaria.  Bashing environmentalists won’t do anything to relieve human suffering nor eliminate the disease, so we can bash environmentalists again next World Malaria Day, and next Earth Day — all at no cost to us, safe in our Wall Street Journal offices in Manhattan, New York, U.S.A.  The Journal has fallen victim to bold purveyors of junk and voodoo science, and bogus and voodoo history.  Shame on the Journal.

Curing the disease in humans means the mosquitoes are mere nuisances, and no longer vectors of disease.  Killing the mosquitoes with poison means the disease will be back with a vengeance in a few weeks or months.  Curing humans is more difficult, and more costly — but it saves lives and can save Africa.  We cannot poison Africa to health.

It’s curious, though:  How did they get so poisoned by DDT, up in that office building?

Decline and fall of the Wall Street Journal — DDT poisoning to blame?

April 27, 2010

Rupert Murdoch’s purchase of the Wall Street Journal provoked groans in 2007, but especially among those of us who had dealt with the news teams of the paper over the previous couple of decades.

For good reason, we now know.  An opposite-editorial page article in the European edition shows why.

Wall Street Journal images - Gothamite New York image

Richard Tren and Donald Roberts, two anti-environmentalist, anti-science lobbyists, wrote a slam at scientists, environmentalists, malaria fighters and the UN, making false claims that these people somehow botched the handling of DDT and allowed a lot of children to die.  Tren, Roberts and the Wall Street Journal should be happy to know that their targeting essentially public figures, probably protects them from libel suits.

Most seriously, the article just gets the facts wrong.  Facts of science and history — easily checked — are simply stated erroneously.  Sometimes the statements are so greatly at odds with the facts, one might wonder if there was malignant intent to skew history and science.

This is journalistic and newspaper malpractice.  Any national journal, like the WSJ, should have fact checkers to check out at least the basic claims of op-ed writers.  Did Murdock fire them all?  How can anyone trust any opinion expressed at the Journal when these guys get away with a yahoo-worthy, fact-challenged piece like this one?

Tren and Roberts make astounding errors of time and place, attributing to DDT magical powers to cross space and time.  What are they thinking?  Here are some of the errors the Journals fact checkers should have caught — did Murdoch fire all the fact checkers?

  1. Beating malaria is not a question of having scientific know howCuring a disease in humans requires medical delivery systems that can diagnose and treat the disease.  DDT does nothing on those scores.  Beating malaria is a question of will and consistency, political will to create the human institutions to do the job.  DDT can’t help there.
  2. DDT wasn’t the tool used to eradicate malaria from the U.S.  The U.S. Centers for Disease Control — an agency set up specifically to fight diseases like malaria — says malaria was effectively eradicated from the U.S. in 1939.  DDT’s pesticide capabilities were discovered in mid-1939, but DDT was not available to fight malaria, for civilians, for another seven years.  DDT does not time travel.
  3. DDT doesn’t have a great track record beating malaria, anywhere. Among nations that have beaten malaria, including the U.S., the chief tools used were other than pesticides.  Among nations where DDT is still used, malaria is endemic.  DDT helped, but there is no place on Earth that beat malaria solely by spraying to kill mosquitoes.  Any malaria fighter will tell you that more must be done, especially in improving medical care, and in creating barriers to keep mosquitoes from biting.
  4. Beating malaria in the U.S. involved draining breeding areas, screening windows to stop mosquitoes from entering homes, and boosting medical care and public health efforts. These methods are the only methods that have worked, over time, to defeat malaria.  Pesticides can help in a well-managed malaria eradication campaign, but no campaign based on spraying pesticides has ever done more than provide a temporary respite against malaria.
  5. DDT is not a magic bullet against malaria. Nations that have used DDT continuously and constantly since 1946, like Mexico, and almost like South Africa, have the same malaria problems other nations have.  Nations that have banned DDT have no malaria.
  6. DDT has never been banned across most of the planet.  Even under the pesticide treaty that specifically targets DDT-classes of pesticides for phase out, there is a special exception for DDT.  DDT was manufactured in the U.S. long after it was banned for agricultural use, and it is manufactured today in India and China.  It is freely available to any government who wishes to use it.
  7. People in malaria-prone areas are not stupid. Tren and Roberts expect you to believe that people in malaria-prone nations are too stupid to buy cheap DDT and use it to save their children, but instead require people like Tren and Roberts to tell them what to do.  That’s a pretty foul argument on its face.
  8. DDT is a dangerous poison, uncontrollable in the wild. Tren and Roberts suggest that DDT is relatively harmless, and that people were foolish to be concerned about it.  They ignore the two federal trials that established DDT was harmful, and the court orders under which EPA (dragging its feet) compiled a record of DDT’s destructive potential thousands of pages long.  They ignore the massive fishkills in Texas and Oklahoma, they ignore the astounding damage to reproduction of birds, and the bioaccumulation quality of the stuff, which means that all living things accumulate larger doses as DDT rises through the trophic levels of the food chain.  Predatory birds in American estuaries got doses of DDT multiplied millions of times over what was applied to be toxic to the smallest organisms.
    DDT was banned in the U.S. because it destroys entire ecosystems.  The U.S. ban prohibited its use on agriculture crops, but allowed use to fight malaria or other diseases, or for other emergencies.  Under these emergency rules, DDT was used to fight the tussock moth infestation in western U.S. forests in the 1970s.
  9. Again, DDT’s ban in the U.S. was not based on a threat to human health. DDT was banned because it destroys natural ecosystems. So any claim that human health effects are not large, misses the point.  However, we should not forget that DDT is a known carcinogen to mammals (humans are mammals).  DDT is listed as a “probable human carcinogen” by the American Cancer Society and every other cancer-fighting agency on Earth.  Why didn’t the Journal’s fact checkers bother to call their local cancer society?  DDT is implicated as a threat to human health, as a poison, as a carcinogen, and as an endocrine disruptor.  Continued research since 1972 has only confirmed that DDT poses unknown, but most likely significant threats to human health.  No study has ever been done that found DDT to be safe to humans.
  10. Use of DDT — or rather, overuse of DDT — frequently has led to more malaria. DDT forces rapid evolution of mosquitoes.  They evolve defenses to the stuff, so that future generations are resistant or even totally immune to DDT.  Increasing DDT use often leads to an increase in malaria.
  11. Slandering the World Health Organization (WHO), Rachel Carson, the thousands of physicians in Africa and Asia who fight malaria, or environmentalists who have exposed the dangers of DDT, does nothing to help save anyone from malaria.

Tren and Roberts have a new book out, a history of DDT.  I suspect that much of the good they have to say about DDT is true and accurate.  Their distortions of history, and their refusal to look at the mountain of science evidence that warns of DDT’s dangers is all the more puzzling.

No world class journal should allow such an ill-researched piece to appear, even as an opinion.  Somebody should have done some fact checking, and made those corrections before the piece hit publication.

Colleague’s Fulbright-Hays trip to Senegal

April 26, 2010

One of my colleagues — an art teacher; you know, the adventurous type — heads off to Senegal this summer on a Fulbright-Hays program.

I’m sorta jealous, of course.  I need time to push our history course to championship level, though — I didn’t apply for anything this summer.

You can track Mr. Adkins’ trip and progress at a blog he’s set up, appropriately called Mr. Adkins’ Great Adventure in Senegal.

If you’re teaching world history, or art, or government, or environmental science, or geography, this might be a great blog to track.

Senegal is a very interesting place.  Note on the map how it completely surrounds its neighbor nation of The Gambia.

FAA map of Senegal

Senegal, map courtesy of the U.S. Federal Aviation Administration (FAA)

France held the nation as a colony once upon a time, from 1850 to independence of the Mali Federation in 1960 — one of the national languages is French, but regional languages are numerous, Wolof, Soninke, Seereer-Siin, Fula, Maninka, and Diola.  The Mali Federation was short-lived, and Senegal broke off in August of 1960.

If you listen to NPR, you’ve probably heard their reporter signing off in that distinct way she does, “Tthis is Ofeibea Quist-Arcton, for NPR, in Dah-KAHHH!”  (Not to be confused with Dacca, Pakistan).

According to the CIA Factbook (online version):

The French colonies of Senegal and the French Sudan were merged in 1959 and granted their independence as the Mali Federation in 1960. The union broke up after only a few months. Senegal joined with The Gambia to form the nominal confederation of Senegambia in 1982, but the envisaged integration of the two countries was never carried out, and the union was dissolved in 1989. The Movement of Democratic Forces in the Casamance (MFDC) has led a low-level separatist insurgency in southern Senegal since the 1980s, and several peace deals have failed to resolve the conflict. Nevertheless, Senegal remains one of the most stable democracies in Africa. Senegal was ruled by a Socialist Party for 40 years until current President Abdoulaye WADE was elected in 2000. He was reelected in February 2007, but has amended Senegal’s constitution over a dozen times to increase executive power and weaken the opposition, part of the President’s increasingly autocratic governing style. Senegal has a long history of participating in international peacekeeping and regional mediation.

The country is tropical, hot and humid.  Geographically, it is low, rolling plains.

Dakar is about as far west as one can go on the African continent.   (See the map inset — Senegal is in dark green).

Senegal has iron ores, and phosphorus (ancient bird droppings?).  It’s not a rich nation, but it’s better off than many developing countries.

Adkins is in for a great adventure, no?

World Malaria Day, 2010 – April 25

April 18, 2010

April 25, 2010, is World Malaria Day.

Malaria plagues too many nations, still.  Between 400 million and 500 million people in the world get infected with one form of the malaria parasites every year.  About a million die, most of those children.  Death disproportionately strikes pregnant women, too.

Life cycle of malaria, from the World Health Organization (WHO)

World Health Organization (WHO) chart on the life cycle of malaria

Advances in medicines and advances in controls of the insects that help transmit the disease led to several campaigns to eradicate the disease over the past 60 years.  Malaria no longer torments most of Europe and most of North America, but it remains a serious, economy-crippling disease across Africa and Asia.

Malaria also poses as a political football.  Over the next couple of weeks you can find dozens of articles on valiant efforts to fight malaria, including the RollBack Malaria Campaign, and efforts by the Gates Foundation and histories of the work of the Rockefeller Foundation.  But you can also find a pernicious political campaign against malaria fighters and “environmentalists,” claiming that DDT is a magic potion that could have ridded the world of malaria by killing off all the mosquitoes, if only that great mass murderer, Rachel Carson, had not imposed her will on the unstable dictators of African nations who did all they could to prove to Ms. Carson that they were environmentally friendly by banning DDT.

All of that is a crock.  But we see it every year.

It’s already shown up in the formerly-known-as-accurate Wall Street Journal, European edition.  (Please watch — I may have more to say on that piece, later.)

Over the next two weeks I will ask myself a hundred times, why do these people fiddle with trying to impugn scientists, physicians and environmentalists, while fevers burn in the brains of children across Africa and Asia?

With action, hope is that we can save the million lives lost annually by stopping malaria, by 2015.  Please consider joining the effort.

You should wonder about that, too.  If you find a good answer, please let me know.

Malaria, DDT and internet myth: Lecture at University of Iowa on January 19

January 14, 2010

Do we have any readers in Iowa City?  Near Iowa City?

A presentation on the history of malaria and DDT, and the recent use and abuse of those stories to flog environmentalists and others on the internet, is set for the Hardin Library for Health Sciences at the University of Iowa in Iowa City, on January 19, 2010 (next Tuesday).

If you’re there, can you snap a couple of pictures to send, and get any handouts, and write up a piece about it?

Here is the press notice on-line:

Presentation on the History of Malaria and DDT

The University of Iowa History of Medicine Society invites you to hear Patrick T. O’Shaughnessy, PhD, Associate Professor, Department of Occupational and Environmental Health, University of Iowa, speak on “Malaria and DDT: the History of a Controversial Association” on Tuesday, January 19th, 5:30 to 6:30, room 2032 Main Library. [in Iowa City, Iowa.]

Dr. O’Shaughnessy observes:  ”Although it helped prevent millions of cases of malaria after its widespread use in the 1950’s, the pesticide DDT was banned from use in the United States and fell out of favor as an agent to reduce cases of malaria around the world. This history of the events associated with the effort to eradicate malaria, as well as the environmental movement that led to the ban on DDT, will center on the story of a story that incorporated both issues and grew into a modern myth still seen in books and multiple websites today.”

The session is free and open to the public.  Light refreshments will be served.

Hardin Library for the Health Sciences stands on the campus in Iowa City.

Maybe I’m not the only bothered by the usual abuse of history and science on the issues of DDT and malaria.

Update: Tim Lambert notes at Deltoid that O’Shaughnessy is the guy who wrote what may be the definitive work on the famous — or infamous — Borneo Cat Drop. If you live in or near Iowa City, this lecture may be a wise investment of time.  High school teachers, your students could benefit, too.
