Cargo cults in global warming, and Arthur Robinson

March 14, 2009

Cargo cult science has deep roots among those who deny global warming or who allow that warming is occurring, but claim we can do nothing about it.  So, it’s no surprise that, at the voodoo science 2nd International Conference on Climate Change, somebody would trot out the old falsehoods about DDT.

According to Traditional Catholic Reflections (you can tell its traditional Catholic because it brooks no comments — you can’t correct an error there):

Speaking at the conference hosted by the Heartland Institute in New York City,[Dr. Arthur Robinson, Director of the Oregon Institute of Science and Medicine] said, “There is a current example of genocide by the removal of technology, and that is the ban on DDT, and that has resulted in the deaths of 30 to 40 million people and has left half a billion infected with malaria.”

It’s malaria that kills people, not a lack of DDT.  The removal of DDT from spraying cotton crops  in Texas and California did absolutely nothing to promote malaria in Africa.  Dr. Robinson needs a basic geography course.  Mosquitoes do not migrate from the U.S. to Africa or Asia.

Stopping the spraying of DDT in the U.S. in 1972 wasn’t a factor in the cessation of usage of DDT in Africa seven years earlier, either.  Dr. Robinson could use some basic math sequencing and calendar reading remediation, too.

Dr. Robinson could use some history and public policy instruction, too.  DDT was never banned in Africa, nor was it banned in India or China which together now produce almost all the DDT used in the world, which is a lot.  There’s no ban on DDT in Uganda, where Dr. Robinson’s friends in the business world are suing to stop the spraying of DDT in huts in affected regions — because they are afraid it will harm their tobacco business.

It’s a heckuva lot easier to throw darts at health care workers and disease fighters than it is to talk about real solutions with these guys.

If Robinson is dead wrong on a one-liner about DDT, how wrong do you think he is in the rest of his presentation on climate change?

Is there any crackpot “scientist” who was not at the Heartland Institute’s wing-ding?


Mapping Africa

February 25, 2009

Here’s a great tool for geography study of Africa.

AfricaMap is based on the Harvard University Geospatial Infrastructure (HUG) platform, and was developed by the Center for Geographic Analysis to make spatial data on Africa easier for researchers to discover and explore.

It’s an interactive tool.  You can capture images (another add-on might be necessary) — but look at all the different layers you can use, live, on your computer.

Good source for student projects, no?

DDT ain’t pixie dust; we can’t poison Africa to health

February 7, 2009

Internet communications spreads information far and wide, but it also spreads disinformation and error far and wide — sometimes faster than good information.

Bill Gates gave a TED* Talk about the need to fight malaria, and where his billions-of-dollars campaign against the disease is going.  Within minutes, the nattering nabobs science ignorance were calling Gates an idiot, and calling for the poisoning of Africa.

Gates, you may remember, is either the richest man in the world or close to it due to his brilliant marketing of Microsoft products.  This would suggest to rational people that he is not an idiot, at a minimum, and perhaps should be listened to on topics which he has researched, such as malaria and mosquitoes.   Africa, you may remember, has a lot of people in it who don’t want to be poisoned, thank you very much. This may suggest that DDT would be controversial even were it a panacea, which it is not.

Rational voices exist.  Deltoid and Bug Girl both provided useful, and accurate information (though in this case, Tim Lambert at Deltoid refers to the DDT controversy on bed bugs, and to another Bug Girl post on research showing DDT won’t help against bed bugs).

Here’s the controversial two minutes of Gates’s talk (you can see it at Bug Girl, too):

Internet and other media now fall into a predictable rhythm:  Any news faintly related to DDT prompts stiff-necked conservatives and other do-nothings who don’t like environmentalists to write stuff calling for a “return” of DDT, making erroneous claims that DDT had made the world safe against malaria, and that only the delusional claims of Rachel Carson convinced everyone to stupidly stop spraying DDT.  And, of course, they then make the erroneous claim that all we need to do to fix everything is bring back DDT.

They don’t ever let the facts get in the way of a stupid, misplaced political hit.

In short, they treat DDT as pixie dust, a magic solution to every problem.  This is fantasy.  In reality, we cannot poison Africa to good health.

I’ve written about these issues before at length.  Hard research, good research, tells us what we have to do to fight malaria

  • Money must be spent to improve health care in Africa, especially to remote populations. Wiping out malaria requires that we get rid of the parasite in humans.  Mosquitoes get the parasite from infected humans, after all — if mosquitoes can’t get infected from humans, we don’t need to worry so much about killing the mosquitoes.  Preventing infections is good; curing those that exist is essential.  Malaria parasites’ ability to grow resistance to pharmaceuticals means we need health care delivery systems that will assure a complete cycle of medical treatment occurs in every victim, and before that, that a quick and accurate diagnosis will allow targeting of the right drug to the specific parasite.
  • Housing improvements will provide huge benefits. Malaria was wiped out in the U.S. and Europe partly by rising incomes.  Even poor people could afford screens on windows, which keeps mosquitoes out of the house, where most infections start.  Housing unsuitable to screening will put a larger burden on bednets.  But better housing is a key part of the fight.
  • Improving incomes help fight malaria. Families with more money can afford better housing, and better health care.  Malaria, and most disease, is very much an “Are Your Lights On” sort of problem.  Victims are the first to know they need to get medical care, and they are in the best position to prevent infections earlier.  If potential victims have the money to buy the tools to fight malaria, malaria has a tough time.
  • Good public works, from local governments, help fight malaria. Good roads work well to fight the disease.  Bad roads develop potholes.  In Africa, potholes fill with water and become breeding sites for mosquitoes.  Well-engineered, well-maintained roads and walkways make great contributions to eliminating malaria.
  • Education on how to avoid malaria pays huge dividends. People who know how to look for mosquito breeding places, and how to eliminate them, are crucial to the elimination of the disease.  Abandoned tires are classic mosquito breeding dumps, but so are rain gutters and even badly-drained flower pots.  When these things occur close to homes, mosquitoes breed there and bite victims close to home.  Since most people spend a signficant amount of time at or near their homes, eliminating these infection opportunities pays off well.  Further, certain breeds of mosquitoes are active at particular hours of the day or night.  Avoiding the places these breeds exist at the hours of their activity prevents malaria infection.  People must be educated to know these things, and to act on them.
  • Bednets work well, and bednets do not prevent the use of other methods. Pitting a fight against bednets and DDT is a favored tactic of pro-DDT groups.  Research shows bednets are very effective without DDT, but that DDT is not effective over the long term without bednets.  A mild solution of DDT applied to bednets in some areas improves the efficiency of the nets.  This is not an one-or-the-other issue.  Bednets always work, insecticides can be used appropriately.  To beat malaria, we will have to use every tool.  Bednets are a great tool, and they will be required regardless the availability or propriety of DDT.

The Bill and Melinda Gates Foundation stepped in to provide money and organization to the fight against malaria a few years ago.  In the last year alone his work and his money have helped prevent millions of cases of malaria, reducing the incidence of the disease by 50 percent in some areas, and 85 percent in others.  Whatever he says about malaria and mosquitoes deserves a good listen at least.

I get e-mail from DDT cranks . . .

January 3, 2009

I noted the errors in a post at Reformed Musings.  Then I noodled around Mr. Mattes’s site,  and I dropped this note into his “about” thread, frustrated that I couldn’t just politely note the errors at his posts, where he’s disabled comments.

I said:

I wish you’d take comments on your posts. For example, you’ve got a couple of errors dealing with DDT in your post on climate change. It looks as though you’re hoping to sneak them past readers, rather than get the science right. I hope that’s not so.  By: Ed Darrell on December 31, 2008 at 7:41 pm

Mattes held that comment in moderation (afraid to let his other readers see it?), but responded in sort by diving deeper into wankery, with a post defending the more crackpot ideas of Michael Crichton, and straying much farther from the science in his claims about DDT and environmenta protection.  Heck, he even trotted out errors about Paul Ehrlich’s writing, apparently not content to be wrong about only DDT and global warming.

So, noting Mattes’s aggravation of his errors, I wrote again on his blog, a bit more sternly:

Shame on you. If you really think DDT is safe and that there was no science behind its “ban,” open comments, let us discuss.

But to compound your errors, and then to fail to approve comments from those who offer you correct information — well, reformation only goes so far, I guess.  By: Ed Darrell on January 2, 2009 at 11:56 am

Rather than open comments to discuss, and rather than respond to the post at the Bathtub, he sent me e-mail:

Shame on me? Excuse me, but I’m a bit amazed at your arrogance. You’ll offer correct information? Why, because others have a different opinion than you they have to be wrong? What are your technical qualifications and applicable experience, besides having a blog and a keyboard? Have you been to Africa? I have. Is racial eugenics your thing? Is that why third-world inhabitants are expendable to you?

Whatever you think you know, DDT is being successfully employed in Africa and elsewhere to save lives every day. No bad effects evident.  None. Their public health officials are literally begging for more. But then, their only agenda is survival. Selective and misleading reporting doesn’t interest them, only results.

Did Mattes miss many of the Tinfoil Hat Brigade’s concerns?

For the record, I don’t share Mattes’s fascination with eugenics as applied to race (and I’ll wager Mattes has no record fighting it); that tends to be a concern of the anti-science, historical revisionists (wrong about history, too).  I said nothing disparaging about third world peoples, and there are a dozen or more posts here to confirm my concerns about health in the third world, in contrast to only the junk science, “Let’s poison the hell out of Africa” attitude from Mattes.

In his second paragraph, he contradicts one of the main points of his first post. He says DDT is being used successfully in Africa — while his first post complained that environmentalists had successfully stopped it from being used.

That’s rather the mark of the true DDT sycophant, someone who suffers seriously from internet DDT poisoning:  The only reason they mention DDT is to find a cudgel to use against brave and smart women like Rachel Carson, or otherwise to criticize people who call for an end to pollution, or the preservation of water, air, trees or animals.  Unanchored by any fact or any need or desire to be accurate, they attack environmenalists, damn the inconsistency of the attacks.

Oy.

He’s followed up today with a new post that assaults science at every turn, claiming to follow science journals, but instead citing the chemical industry supporters like Richard Tren, opposing the Centers for Disease Control and World Health Organization.  While complaining about “eco-socialism,” he approvingly cites the experts of Lyndon Larouche, the late Dr. Gordon Edwards, in all of his errors and all of the political wankery of Larouche.

Mattes has gone back to the false claims that Edmund Sweeney exhonerated DDT, and that “evil” William Ruckelshaus banned DDT anyway — completely murdering Sweeney’s analysis and the law behind it, and completely avoiding the law, the court cases, and the history behind Ruckleshaus’s actions.

In his frantic, apoplectic dance to avoid discussing whether he might be in error, Mattes has dived so deeply into the depths of tinfoil hat sourcery (no, it’s spelled as I intended it) that in the end, he’s not jus twrong, he’s not even wrong.

If someone criticized any translation of the Bible as carelessly and wildly as Mattes criticizes science, he’d be out recruiting neighbors with pitchforks and torches to march.

Mattes claims he’s done with the issue.  We can only hope.  To continue in his current trend, he’d need to deny gravity (both Newton and Einstein), atomic theory, and Linneaus.  But I also suppose it means he’ll never check here to see the facts.  Just when we thought we were making progress . . .

DDT falsehoods, taken as an article of faith

December 31, 2008

Just when you start thinking the world is safe for the facts — safe for the truth — some well-meaning-but-poorly-informed person comes along to remind you that it’s a constant struggle to keep the flame of truth from being snuffed out for no good reason.

Henry I. Miller didn’t publish a screed demanding DDT be misused against West Nile virus this year, which I count as a major victory.  As you know, DDT is the wrong stuff to use to fight West Nile, so calling for DDT in that case merely means you’re an ideologue who wants to slam science, and it probably means you wish disease victims would hurry up and die.  (“More statistics to use against libruls!”)

Henry I. Miller. How many years at the Hoover Institute before he finds the library at Stanford to check his claims on DDT?

Henry I. Miller. How many years at the Hoover Institute before he finds the library at Stanford to check his claims on DDT?

And even Oklahoma’s reigning Senate fool Tom Coburn lifted his hold on the bill naming for Rachel Carson the post office in her hometown.

But, on the second to last day of the year, comes Bob Mattes at Reformed Musings, to claim that climate change is a hoax, and say he knows it’s so because DDT is safe and Rachel Carson was wrong. Mattes is a deacon in a Presbyterian church in Virginia; the name of his site is a reference to reformed theology, I gather.

When someone claims as a matter of faith, things that are well known to be wrong and easily debunked, that someone is unlikely to be swayed by the facts. In fact, Mattes allows no criticism of his post at his blog — he’s turned off comments on that post.

Will he drop by here to read his errors?  Not likely.  Would he correct the errors if he knew?  It’s not good to gamble when the odds are long against you.

Reformed Musings said:

Want a concrete example of the impact of eco-socialism? Three letters – DDT.

Well, no, I don’t want an alleged example of eco-socialism from an eco-fascist, one whose mind is made up, incorrectly, and who will not let the facts sway him.  Notice that the authority he cites is that well-known purveyor of junk science, Junk Science, the ethically-challenged website run by the industry campaign in favor of DDT.  If one dances to the devil’s tune, one should not claim not to be doing the devil’s work.

If this be eco-socialism, it’s God-blessed, and we should revel in it and make the most of it.

In the 60’s, there was the big DDT scare, with activists claiming that the pesticide was killing off our birds and bees.

Right.  And it was true, DDT was killing our birds and bees.  It took more than 30 years of not using DDT to rescue our national symbol, the bald eagle, from DDT’s killer effects.  Is it fair to call it a “scare” if it’s true?

Rachel Carson sold the big lie in her famous book Silent Spring, which was full of misrepresentations.

See, here’s how we know Mattes doesn’t know what he’s talking about, and probably hasn’t read the book.  Carson was very careful in her book.  She offered more than 50 pages of citations to science papers and hard research to support what she wrote — a “don’t take my word for it, check it out for yourself” kind of honesty.

Discover magazine carried an article about DDT and Carson’s book in November 2007Discover said that, since 1962, more than 1,000 peer-reviewed publications support Carson’s conclusions, a record remarkable in any branch of science.

In fact, Carson may have underestimated the impact of DDT on birds, says Michael Fry, an avian toxicologist and director of the American Bird Conservancy’s pesticides and birds program. She was not aware that DDT—or rather its metabolite, DDE—causes eggshell thinning because the data were not published until the late 1960s and early 1970s. It was eggshell thinning that devastated fish-eating birds and birds of prey, says Fry, and this effect is well documented in a report (pdf) on DDT published in 2002 by the Department of Health and Human Services’ Agency for Toxic Substances and Disease Registry (ATSDR). The report, which cites over 1,000 references, also describes how DDT and its breakdown products accumulate in the tissues of animals high up on terrestrial and aquatic food chains—a process that induced reproductive and neurological defects in birds and fish.

Had Mattes been paying attention (was he even alive then?), he’d have noted that President John F. Kennedy tasked the President’s Science Advisory Council to check out Carson’s book, to see whether it was accurate, and whether the government should start down the path of careful study and careful regulation of pesticides as she suggested.  In May 1963 the PSAC reported back that Carson was dead right on every issue, except, maybe for one.  PSAC said Carson wasn’t alarmist enough, that immediate action against pesticides was justified, rather than waiting for later studies or delaying for any other reason.

So, here I issue a challenge to Bob Mattes:  Tell us where Rachel Carson was wrong.  Cite for us a page in Silent Spring where she made a significant error in science, a point that has not been borne out as correct in later studies.

I’ve been making this challenge for a year and half now, and not even Stephen Milloy has been able to offer a single error Carson made.  A few have said they “heard” Carson erred in one thing or another, but upon checking, we’ve always found that the claimed errors were nowhere to be found, or the errors alleged were misstated, or, more often, what was claimed as error simply was not.

It’s a very odd situation:  We have a deacon of the Presbyterians assaulting the honor of a distinguished scientist, using false claims as his ammunition.

As usual, the ignorant entertainment industry frothed at the mouth for the new fad cause. Joni Mitchell sang: “Hey, farmer, farmer, put away that DDT now. Give me spots on my apples but leave me the birds and the bees.” Cute, huh?

As a result, DDT was banned world-wide. Problem was, not only were the zealots wrong, but nothing killed deadly malaria-carrying mosquitoes better than DDT.

DDT has never been banned worldwide.  It’s still manufactured in several places — it’s still a deadly hazard in India.  It’s been in constant use in many nations, such as Mexico and South Africa.  Limitations on DDT use have always included a loophole allowing DDT to be used to protect against malaria — even the 2001 Persistant Organic Pesticides Treaty has a special clause allowing DDT to be used against malaria.

So it’s false to claim that DDT was banned worldwide, ever.  We might be much better to get to that position because it would keep nuts from claiming that all we have to do is poison Africa to make Aricans healthy — but in any case, there is no ban on DDT to fight malaria.

Use of DDT began to decline in the mid 1960s when mosquitoes began to exhibit resistance and even immunity to the stuff.  Genetic studies now find that almost all mosquitoes in the world have multiple copies of a gene that allows the bug to digest DDT more as a nutrient, rendering it ineffective as a pesticide.  The World Health Organization had begun an ambitious campaign to knock down mosquito populations long enough that malaria would die out; but by the mid 1960s, the burgeoning resistance to DDT rendered that campaign untenable.  DDT use against mosquitoes, which was never undertaken in much of Africa because some local governments were not stable enough to manage an anti-mosquito campaign, declined, and stopped in places where DDT simply did not work.

In fact it was gross overuse of DDT by agricultural interests that drove the resistance among insects.  Had that overuse been controlled earlier, we might have been able to kill of malaria.  It was not a ban on DDT that caused its use to decline.  It was that DDT stopped working.  No one in their right mind will spend money on a pesticide that doesn’t work, no matter how cheap the stuff is.

But it wasn’t popular culture that got DDT banned.  In the late 1960s litigation on DDT spraying worked through the courts.  By 1972, two federal courts ruled in separate cases that the federal government had failed to carry out its obligations to control the use of DDT as required by law, based on evidence presented in court that demonstrated clear harm.  Both courts ordered the government to promptly hold the administrative hearings necessary to alter the registration for DDT.  The hearings started in the Department of Agriculture, which moved slowly.  When the Environmental Protection Agency (EPA) was created, it got the authority to regulate pesticides from Ag.  The courts ordered EPA to get off its duff and speed the process.

In the midst of a nine-month-long hearing process that accumulated thousands of pages of scientific documentation of the harms of DDT, manufacturers of the pesticide voluntarily changed their labels to limit use of DDT essentially to emergency situations, not general broadcast applications. Judge Edmund Sweeney, the EPA administrative law judge, thought that change, which was what was pending, meant that EPA did not need to act, and he so ruled at the end of the process.  EPA Administrator William Ruckleshaus, a veteran of more recent environmental litigation, understood the courts had ordered a more ironclad change, and he imposed tighter registration standards on DDT that prohibited its use on agricultural crops, except in emergencies.  There was also a loophole built in to protect public health.

DDT manufacturers sued EPA to overturn the rule.  The courts ruled that the scientific evidence was overwhelming, and that EPA’s rule was firmly grounded.  The manufacturers did not appeal further.  So, DDT use in the U.S. was severely restricted by the end of 1972, following earlier restrictiosn in Sweden.

Can Mattes read a calendar?  How does a ban on DDT in Sweden in 1970, in the U.S. in 1972, make Africa stop using DDT in 1965?

Literally millions of poor have needlessly died from malaria in Third World countries as a result of the ban. Malaria is the 4th leading cause of death in the world. Drug-resistant strains are starting to dominate. Eradication is the real answer. Only recently have countries like South Africa defied the ban and started spraying DDT again to fight malaria. Ideas have consequences – eco-socialism routinely kills, just not in the comfy apartments of the self-serving eco-socialists.

What ban is he talking about? South Africa suspended DDT use only briefly at the end of the 20th century — but South Africa’s problems are not caused because South African mosquitoes roared back when they were not sprayed wholesale with DDT.  Malaria in South Africa rose when the disease came over the border from other nations where the disease was less controlled.  South Africa brought back DDT use, though in a more limited fashion.  There was no ban to defy.  Mattes is telling a whopper here.

Mattes cites the Centers for Disease Control when he says malaria is the fourth leading killer in the world.  He either fails to notice or fails to say that CDC does not ask for DDT to be brought back to fight malaria.  CDC calls for bednets, for draining of breeding areas, for better medical care and better diagnosis, but not for more DDT.  Why?  When the leading disease fighting organization in the world does not ask for DDT, we might assume it puts DDT way down on its list of priorities (as it does).  Remember, CDC’s origins were in the fight against mosquito-borne diseases.  CDC speaks with authority on mosquito eradication.  CDC does not ask for more DDT, anywhere.  His own authority — he should listen to them.

Health care professionals note that malaria made a serious resurgence when the malaria parasites themselves became resistant to the pharmaceuticals used to treat them.  This has nothing to do with DDT, because DDT is not given as a drug to humans (it’s a poison, mildly carcinogenic, and there is no demonstrated effectiveness against the parasite).

Can Bob Mattes read a map?  How do restrictions on spraying DDT on cotton fields in Texas, cause malaria to increase in Africa?

Mattes closes his post:

History shows that the eco-socialists have NEVER been right. EVERY scare prediction they’ve ever tried fails to materialize. Unfortunately, history starts today for most folks. We don’t teach logic or real science in public schools anymore, just the religion of political correctness. Ignorance breeds disaster, especially for those in developing countries who can’t speak for themselves and don’t have a George Soros funding their latest fad cause. Remember DDT. Remember global cooling. Remember the limitations of computer modeling. Don’t be duped.

Except, the “eco-socialists” as Mattes mislabels them were right about DDT, they were right about malaria, they were right on the science about wildlife damage from DDT, and they were right on the history.

Ignorance does indeed breed disaster, which is where Mattes’s views will take us.  He should carefully consider his closing trio of words, and follow them religiously.

If Mattes is so wrong on every claim about DDT, do you think we should trust anything he says about climate change?

Beating malaria without DDT

November 3, 2008

I told you so.

Recent research and assessments of anti-malaria campaigns in Africa show dramatic results from the use of bed nets and other non-DDT spraying methods.

Rachel Carson was right.

I was compelled to jump into this issue when Utah’s U.S. Rep. Rob Bishop made a silly and incorrect statement against Rachel Carson, after his failed attempt to derail a bill to rename a post office in her honor on the 100th anniversary of her birth.  The slam-Rachel-Carson effort turned out to include Oklahama U.S. Sen. Tom Coburn (who has since recanted), and an array of anti-science types who rail against “environmentalists” and made astoundingly false claims against Carson’s work and Carson herself.

In those cases, Carson’s critics called for a return of massive spraying of DDT.  Eventually most of them backed off of calling for outdoor spraying.  Eventually Sen. Coburn lifted his hold on the post office renaming legislation (and it passed).

The calumny continued on the internet, however, with an active hoax campaign for DDT and against environmental protection and Rachel Carson.  Steven Milloy joined Lyndon Larouche in promoting the anti-Carson screeds of the late Dr. Gordon Edwards, a UC Davis entomologist who argued against science that DDT was harmless to humans and animals.

Enough about history.  Look at the real results on the ground, today:

First, note the study published in Lancet that documents a dramatic decrease in malaria in Gambia, using “low-cost” strategies that include bed netsAgence France Presse carried a summary of the study. [Another link to the same AFP article.]

Incidence of malaria in Gambia has plunged thanks to an array of low-cost strategies, offering the tempting vision of eliminating this disease in parts of Africa, a study published Friday by The Lancet said.

At four key monitoring sites in the small West African state, the number of malarial cases fell by between 50 percent and 82 percent between 2003 and 2007, its authors found.

The tally of deaths from malaria, recorded at two hospitals where there had been a total of 29 fatalities out of 232 admissions in 2003, fell by nine-tenths and 100 percent in 2007. A fall of 100 percent means that no deaths attributed to malaria occurred that year.

“A large proportion of the malaria burden has been alleviated in Africa,” the study concludes.

Also see:

Second, note that malaria rates also fell in Kenya, with a shift in infections away from young children, a very good sign. TropIKA.net carried a summary of that study.

Toronto’s Globe and Mail carried a longer story on Kenya’s experience, “Malaria a rare public-health success story in Africa.”

“We had to stay home and tend the sick – you can never leave them to go and work in the fields – and then there was no income and we were hungry. So truly, that 100 shillings was a great investment.”

The family heard about the importance of using a bed net to fend off malaria in a sermon at church, and then on the radio. Now, a year later, they would be able to get them for free, as Kenya ramps up its efforts to get every single citizen sleeping under a net.

Already, two-thirds of Kenyan children are sleeping beneath them and, as a result, child malaria deaths have fallen by 40 per cent in the past two years.

This remarkable success story has been repeated across much of Africa: Deaths of children under 5 declined 66 per cent in Rwanda from 2005 to 2007 and by 51 per cent in Ethiopia.

“This really is the one global public-health story that is simply and straightforwardly positive,” said Jon Lidén, spokesman for the Global Fund to Fight AIDS, Tuberculosis and Malaria, which has been behind much of the push.

“It’s not a gradual change. It’s a fundamental change in the fight against malaria.”

Yet the decidedly unglamorous innovations responsible for the change – spraying houses, treating standing water to kill larvae, mass distribution of cheap polyester nets and better drugs, and simple public education on the need to treat suspected malaria quickly – receive almost no attention.

“We never make the headlines with this stuff,” said Shanaaz Sharif, head of disease control for Kenya’s Ministry of Health, which has thus far given out 11 million nets at a cost to the government of $6 each.

Despite pledges from the U.S. to signficantly increase funding to fight malaria, money has not flowed from the U.S., especially for bed nets.  Ironically, Canada is the chief donor of the nets.

Canada has had a key role in this success: The Canadian International Development Agency is the single largest donor of bed nets to Africa – nearly 6.4 million by the end of last year. In addition to government support, Canadian individuals and charities – notably the Red Cross – have embraced the issue by making donations and fundraising.

“Canadians … haven’t got the credit they deserve,” said Prudence Smith, head of advocacy for Roll Back Malaria, a partnership between key global-health agencies and donors such as the Bill and Melinda Gates Foundation.

Not all news is good. In Zimbabwe, dictator Robert Mugabe misused $7.3 million in malaria-fighting money from the Global Fund to Fight AIDS, Tuberculosis and Malaria. So far, he has not repaid the Global Fund. Politics continues to kill Africans, not an absence of DDT.

In India, where DDT use is untallied, manufacture massive, and use virtually uncontrolled, malaria is resurgent. According to The Telegraph in Calcutta, malaria is epidemic among people living in poorer sections of the city, often with fatal results.  ExpressIndia.com’s headline tells the story:  “Malaria puts city on the edge:  toll rises to 8.”

Public health officials in India will step up information and education campaigns, and urge residents “not to panic.”

  • “Warsaw 1920, a quality read” – What?  Your world history text didn’t mention Poland’s abortive attempt to liberate the Ukraine from the USSR in 1920, nor Lenin’s invasion of Poland and march on Berlin, nor the heroic stand at the Vistula described here as one of the most important military victories in history?  You’e better read this post, too, and maybe buy the book.
  • “The coming anarchy – Kaplan’s piece and the blog” — Robert Kaplan’s article in the 1994 The Atlantic described the woes of Africa.  14 years later, it’s still a good read and full of insight.  I wasn’t thinking of using that in world history in 1994 . . . I wasn’t thinking of teaching in 2008 in 1994.  Eoin Purcell’s reminders and pointers prove useful and informative once again.

Solid research on controlling malaria

October 20, 2008

Looking for other things, I stumbled into two research journal articles on the fight against malaria.  Neither calls for a return to broadcast spraying of DDT; neither claims the ban on agricultural use of DDT had any significant effect on the rise of malaria.

Both are loaded with serious research that exposes DDT advocates as charlatans.

First:  from Clinical Microbiology Reviews, October 2002, p. 564-594, Vol. 15, No. 4
0893-8512/02/$04.00+0; DOI: 10.1128/CMR.15.4.564-594.2002. “Evolutionary and Historical Aspects of the Burden of Malaria,” by Richard Carter and Kamini N. Mendis:

SUMMARY:  Malaria is among the oldest of diseases. In one form or another, it has infected and affected our ancestors since long before the origin of the human line. During our recent evolution, its influence has probably been greater than that of any other infectious agent. Here we attempt to trace the forms and impacts of malaria from a distant past through historical times to the present. In the last sections, we review the current burdens of malaria across the world and discuss present-day approaches to its management. Only by following, or attempting to follow, malaria throughout its evolution and history can we understand its character and so be better prepared for our future management of this ancient ill.

Second, from Joel G. Bremen, Martin S. Alilio, and Anne Mills, “Conquering the Intolerable Burden of Malaria:  What’s New, What’s Needed:  A Summary,” Am. J. Trop. Med. Hyg., 71(2 suppl), 2004, pp. 1-15 (The American Journal of Tropical Medicine and Hygeine).

High school kids, there are the sources you need for your papers on the fight against malaria.


Malaria/DDT Carnival addendum

October 11, 2008

It’s almost as interesting that these posts show up on the same day, as what they say.

Following on the heels of the impromptu Malaria/DDT carnival earlier in the week, take a look at these posts:


Carnival of Fighting Malaria (and DDT)

October 8, 2008

It’s been about a year since the first, completely impromptu Carnival of DDT.  Last fall, in October and November, there was enough going on about DDT to merit something like a blog carnival, with a second in November.

My news searches today turned up a number of items of interest in DDT and fighting malaria — enough to merit another summary post, IMHO.  Here goes.

First, Tim Lambert at Deltoid sets straight the history of the policy of the World Health Organization (WHO) with regard to DDT use, and whether WHO caved in to pressures from environmentalists to completely ban DDT, as Roger Bate had earlier, erroneously said.  Tim has a number of well-researched, well-reasoned posts on DDT and health; people researching the issue should be sure to visit the archives of his blog.  But for today, make sure you read “Roger Bates’ false history.

This Friday the Hawk Mountain Sanctuary presents an award to Tom Cade, the Boise, Idaho guy credited with doing much to save the endangered peregrine falcon. You can read about it in the Allentown, Pennsylvania, Morning Call.

Cade played a major role in reviving the nearly extinct peregrine falcon in the 1970s. As a graduate student, he studied how a pesticide contributed to their sharp population decline. He eventually founded a conservation group, The Peregrine Fund, which reintroduced captivity-bred birds to the wild.

. . . The falcon’s revival is widely considered one of the most successful recoveries of an endangered species. The species teetered on the brink of extinction in 1970, when as few as 39 known pairs of nesting falcons existed. A 2003 survey puts the number of nesting pairs at more than 3,100.

On Thursday Cade will receive the Sarkis Acopian Award for Distinguished Achievement in Raptor Conservation.  According to The Morning Call, “The award is given infrequently by Hawk Mountain officials and is named after the Kempton-area bird sanctuary’s primary benefactor, a late philanthropist who studied engineering at Lafayette College.”

Also, see this story about the recovery of peregrines in Canada, from the Sudbury Star.

Bug Girl tells the story of a new documentary on the Michigan State University professor who documented the deaths of songbirds made famous in Rachel Carson’s book, Silent Spring. Dr. George J. Wallace’s work became the subject of an article in Environmental Journalism in 2005.  Students and faculty at MSU’s Knight Center for Environmental Journalism produced the movie, “Dying to Be Heard.”  Be sure to check out the comments at Bug Girl, for more information.

International health care expert César Chelala argues that the “War Against Malaria Can Be Won, Without DDT” at the on-line Epoch Times. Chelala reports on a project in Mexico — where DDT use has never stopped since 1946 — a project now extended to other places in Central America, demonstrating that the tried and true methods of preventing mosquitoes from breeding and avoiding contact work well to fight malaria.  Plus, he says, it’s cheaper than using DDT.  Doubt that it could work?  Chelala points out that the Panama Canal could not be dug without controlling mosquito-borne illnesses, and the Canal was opened in 1914, 25 years before DDT was demonstrated to be deadly to insects, more than 30 years before widespread deployment of DDT.

Early detection and treatment is critical to eliminate the parasite carriers. An important aspect of this project has been the collaboration of voluntary community health workers who are taught to make an early diagnosis in situ and to administer complete courses of treatment not only to those affected but also to the patients’ immediate contacts.

The project was carried out in specific pilot areas called “demonstration areas” which had been selected due to their high levels of malaria transmission. In those areas, the number of malaria cases fell 63% from 2004 to 2007. In several demonstration areas I visited in Honduras and Mexico as a consultant for the Pan American Health Organization malaria had practically been eliminated. Plans are underway to expand the project to other regions where malaria remains a serious threat.

One of the advantages of not using DDT (besides avoiding its toxic effects) is the enormous savings realized from discontinuing its routine use. These savings can now be put to good use with other diseases.

You might also want to view Chelala’s description of solutions for public health crises in Africa, at The Globalist.

Chelala’s cool, clear and accurate reporting sadly contrasts with the hysteric and wrong reporting at Newsbusters and other polemical outlets on the web, seemingly bent on perpetration of the hoax that DDT is harmless and Rachel Carson was wrong.

Liz Rothchild’s one-woman play about Rachel Carson, “Another Kind of Silence,” got good reviews upon opening at the Warehouse Theatre, in Croydon, England.

Meanwhile, from Uganda comes news that DDT spraying failed to reduce malaria in spraying done in that nation. Proponents expected a sharp and steep decline in malaria, but numbers are not greatly reduced.  Even after taking account for the legal difficulties of spraying, after conservative businessmen sought an injunction to stop DDT use, the results do not speak well for DDT’s effectiveness.

Contrary to expectations, data collected by health departments in Apac and Oyam districts, which record the highest malaria incidence in the world, do not reflect significant improvements since DDT spraying ended prematurely. From May to July 2008, which is the period immediately following the spraying, between 400 and 600 clinical malaria cases per 100,000 of the population were reported per week in Oyam; and 600 to 800 such cases in Apac for the same period. These are almost exactly the same as the number of cases reported between January and April 2008.

Getting news out of Africa is not always easy.  Reading reports from Ugandan papers, it becomes clear that reporting standards differ greatly from the U.S. to Uganda.  Still, the saga from Uganda demonstrates that DDT is no panacea.  Uganda is a nation that had not used DDT extensively prior to the mid-1960s.  Resistance to use now comes from tobacco and cotton interests who speciously claim that potential DDT contamination of crops would result in the European Union banning vital Ugandan exports.  The legal issues all alone assume Shakespearean tragedy dimensions.  Or, perhaps more accurately, we could call the story Kafkaesque.

Happily, we have evidence that younger people show concern about DDT pollution, in a story about the stuff in Teen Ink magazine.

A study in the UK finds DDT present in colostrum, the vital pre-milk substance newly-lactating mothers create for their babies, as well as in later breast milk.

Bed bugs continue their own surge on Americans, and knee-jerk writers editorialize for the return of DDT, completely unaware that bed bugs are among those critters most resistant to DDT, and unaware that there are other, more effective solutions.

James McWilliams writes in The Texas Observer that most of us are ecological illiterates, which makes control of pollution more difficult, in a review of a new book, The Gulf Stream. Canny readers will recognize McWilliams as the author of the recently-published book, American Pests: Our Losing War on Insects from Colonial Times to DDT.

Sandra Steingraber will lecture on November 11 in Philadelphia on “The Many Faces of DDT,” part of a series of lectures sponsored by the Chemical Heritage Foundation, “Molecules That Matter.”  Steingraber is the author of Living Downstream:  An ecologist looks at cancer and the environment.

Canada’s Leader-Post reports that Chinese food processors have been caught using DDT in food to reduce insect infestations.  The cycle starts all over again.

Time for this carnival’s midway to shut down for the night.  Don’t let the bed bugs bite.


DDT results disappointing in Uganda

October 3, 2008

October 2008 — Uganda is nearing the end of the season when the national health service sprays DDT inside homes to discourage mosquitoes from biting, and spreading malaria.  Results from DDT use this year show no improvement over the previous year, and in some cases malaria rates are higher.

The story from The Observer in Kampala, via All-Africa.com news, provides some of the details, but little analysis to be debated.  Is the failure of the program due to partial implementation, since implementation was resisted by businesses and cotton farmers?  Or is DDT simply ineffective?  It’s nearly impossible to tell from data available so far.

Below the fold, the story in its entirety.

John Stossel: Wrong again, on DDT

September 17, 2008

John Stossel’s new book makes a detour to rail against the regulation of DDT and against Rachel Carson and her book, Silent Spring.

I’ve not read the book, but from what I’ve read about it, he’s got it dead wrong.  If the example offered by Grokmedia is their own, and not Stossel’s, shame on them.  (Stossel’s complained about DDT before, though, and gotten the facts as wrong as Grokmedia has them.)  The claims are unbelievable:

Consider the chemical DDT. I’m sure, if you’ve heard anything at all about DDT, it’s that it’s a horrible, deadly chemical, that must be banned to preserve the public’s safety. The truth is, the only thing DDT affects are mosquitos. Not humans. In fact, I’m old enough to remember trucks pulling through our neighborhood and spraying the stuff into the air, like gigantic clouds, bringing death – to the mosquito population. These clouds of DDT harmed no one. There were no great increases in any kind of cancer or other fatal diseases – and certainly none that could be associated with DDT. Enter the book, Silent Spring.

A woman by the name of Rachel Carson wrote a book that vilified DDT, and blamed our love of chemical solutions for her own cancer. (She died of breast cancer two years after the publication of her book.) Silent Spring is almost single-handedly credited with triggering a worldwide ban on DDT. The result of this ban has been, paradoxically enough, millions of deaths in countries like Ethiopia, where malaria kills due to mosquito infestations. U.S. aid policy bans sending money to any country that chooses to spray with DDT.

How did Silent Spring cause this wave of destruction? Marketing. The book was marketed by it’s publishers. The marketing efforts attracted the attention of a mainstream media hungry for stories that scare the populace to death. The unwashed masses Demanded That Something Be Done. Politicians, eager to grandstand (and free of conciences that might give them pause to think about the Law of Unintended Consequences) passed laws, and that was that.

Here’s what I wrote in comments to the post at Grokmedia, which appears to have gone into their own hell for any post that disagrees with their views:

Stossel said that about DDT?  Once again, he’s gone off the rails.

Do you seriously think that a book publisher with its meager PR budget could derail a multi-billion-dollar pesticide manufacturing industry that was led by several of America’s top 100 corporations?  Do you think corporations are really that incompetent at the public relations game?

The truth is that DDT was banned because of its harm to the environment, not due to its dangers to human health (though, to be perfectly accurate we should note that every cancer-fighting agency on Earth says DDT is a probably human carcinogen, and recent research has strengthened the links between cancer in people exposed to DDT in their mother’s breast milk and in utero, and that DDT is now known to be a rather nasty endocrine disruptor in all animals).  More than a thousand studies confirmed the dangers of DDT to birds and other predators higher up in food chains, especially in estuarine waters.

No one passed a law banning DDT.  If the action was popular, that was beside the point.  In 1962, in response to the half-million-dollar slander campaign against Carson by the pesticide manufacturers (don’t take my word for it — look it up), President Kennedy asked his Science Advisory Council to scrutinize the book.  In May 1963 they reported back that Carson was correct on all counts but one — they said Carson went too easy on the dangers of DDT, and that action needed to be taken right away to stop its use.  Kennedy dallied, however, and did little before he died.

The “ban” on DDT came nearly a decade later, in 1972.  It was not due to any “junk science” law (an interesting claim since it is based on junk science itself).  Two federal courts had ordered EPA to speed up its analysis of the registration of the pesticide, in lieu of simply ordering the stuff off the market after two entirely different lawsuits.  Pesticide manufacturers had been defendants in both lawsuits, and they put up a more than vigorous fight — but they lost on the science.

EPA dragged its feet, but finally acted against DDT in 1972, effectively banning the broadcast spraying of DDT on crops, but leaving it available for things like malaria control.  Of course the ruling was challenged in court, since under U.S. law, had the ruling been only popular, and not based on considerable evidence, the courts would have been obligated to nullify the ruling.  In two separate challenges, the courts ruled that EPA’s action was solidly based on the scientific evidence, and therefore would stand.

That’s quite a bit different from the picture Stossel paints, I gather.  Is this, perhaps, his first foray into fiction?

And, did you catch the contradictions?  The author claims mosquito abatement in Ethiopia is hampered by a lack of U.S. aid, as a result of Rachel Carson’s book in 1962.  Do they know that George Bush is president?  Do they really think Bush and Cheney are tools of Rachel Carson?  Do they know that bed nets have cut malaria rates by half where they were used in Ethiopia?

Looks like another example of DDT poisoning to me.


African nations back off of limited DDT use

August 7, 2008

Anti-DDT business interests appear triumphant, if only temporarily,  in their efforts to stop the use of DDT in the fight against malaria.

ProtectAfrica.com reports use of DDT has been stopped in northern UgandaNine corporations sued to stop the sprayingNew Visions reports a shift to a chemical named ICON for use in Indoor Residual Spraying, designed to protect people against mosquitoes in their homes.

I have links to stories saying Rwanda has abandoned DDT in the past few weeks, but none of the links work.

Meanwhile, from The East African in Nairobi, Kenya, comes the report that Tanzania became the first East African nation in recent years to use DDT for limited, indoor spraying. [But be wary of this source; the article also claims many nations outlawed DDT after 1972; not accurate in Africa, nor most other places.]

There is high irony in businesses opposing the use of DDT when environmental organizations in other nations do not oppose it.


Uganda and malaria, from the inside

July 30, 2008

This is probably as close to we can come to know what’s going on inside Uganda, especially with regard to malaria and efforts to fight it there.  Go see Mars and Aesculapius, “World Malaria Day.

As you can see, simply pumping DDT into the countryside is unlikely to solve the problems.


Exciting times dept.: New inflation control – no paper to print money

July 29, 2008

This year is an exciting time to be teaching history, government or civics, or economics. So many events in national politics and in the world expose the workings of government, politics and history, that teachers should have smoking scissors by the time they finish the morning newspaper.

From Agence France Presse - A Zimbabwean $50 million note in April, not enough to buy a banana

Image from The Guardian/EPA - A Zimbabwean $50 million note in April, not enough to buy a banana; worth less than $0.01 US now

Zimbabwe’s unbelievable inflation rates are textbook cases for economics and government teachers, aren’t they? Inflation has been running more than 1 million percent for some time. Reports I saw a few days ago said inflation is now at something like 2 million percent — in a story about a new currency being printed there, the Zimbabwean $100 billion note.

Authorities last week released a new $100 billion bank note. By Sunday it was not enough even to buy a scarce loaf of bread in what has become one of the world’s most expensive — and impoverished — countries.

Is that a cruel enough example to get the attention of high school economics students?

But the story has gotten even more bizarre. Even with a government making absolutely no effort to control inflation, supply and demand can put a crunch on affairs.

Zimbabwe has run out of paper upon which to print the money to pay government workers.

So the elaborate work by the despotic Robert Mugabe to keep his hold on the reins of power, the carefully planned murders of opposition political workers, the threats of violence if the vote didn’t go his way — all of that may come crashing down. Mugabe can’t print money to pay the thugs to terrorize the people. The thugs may turn on Mugabe.

The government is reported to have run out of paper to print money and is believed to be panicking over how to pay salaries for civil servants, especially soldiers and police who are the backbone of the Mugabe dictatorship. From AllAfrica.com, a report from SW Radio Africa:

Giesecke & Devrient, the European company that was providing the paper, was last month pressured to cut supplies by the German government, after protests were threatened. In addition, a company that provides the software licences for the design and printing of the banknotes, is reported to be considering withdrawing their contract.

The military has helped run the country for some years now and the Mugabe regime needs to sustain military and police operations in order to maintain political control. There is much consensus among observers that Mugabe’s recent decision to sign the Memorandum of Agreement with the two MDC formations was clearly based on increased economic pressure. One English pound this week is trading at Z$1.3 trillion.

Earlier in the week, Mugabe was out of the country trying to negotiate a power-sharing agreement with his opposition, Morgan Tsvangarai. What power will be left to share?

The software for the notes, which is supplied by a Hungarian-Austrian company called Jura JSP, is reportedly very technical. The UK Guardian newspaper quoted a ‘knowledgeable source’ at the Zimbabwe government’s Fidelity Printers, who said the software issue was a major problem and had created an air of panic. “They are in a panic because without the software they can’t print anything,” the source added.

Helmoed-Romer Heitman, the South Africa correspondent for Jane’s Defence Weekly (a global military security publication) said the situation faced by the regime is quite typical of many African countries that are falling apart. He said the result tends to be at least violent demonstrations, if not a mutiny by the military.

“Given the current situation in Zimbabwe, I am inclined to think that a lot of the military, certainly middle ranking officers and some seniors, are not all that enamoured of the party that is running the show”, said Heitman.

Oh, and that 2 million percent inflation?

With experts estimating that the inflation rate is currently at 15 million per cent, and pressure on those doing business with the Mugabe regime increasing, the economy has proved to be the straw that finally broke the camel’s back.

Today comes word that the government plans to revalue Zimbabwean money, lopping a few zeroes off, to make it sound more rational.

Observations: First, these are great examples to use in classes, stark contrasts of inflation out of control. Second, Mugabe is riding a tiger, finally, after holding power for several decades. He should study the words of Winston Churchill. Churchill wrote, in While England Slept:

“Dictators ride to and fro upon tigers which they dare not dismount. And the tigers are getting hungry.”

If you read this blog regularly, you may wonder with me, is there a malaria problem in Zimbabwe? If so, how will the wackoes blame all of this on Rachel Carson?
