DDT

A recent study links exposure to the insecticide DDT to Alzhiemer’s disease. According to the study, even exposure to DDT decades ago may lead to a person developing the disease later in life.

DDT — a World War II-era pesticide used extensively in the U.S. until it was banned in 1972 — accumulates in people’s bodies and persists for decades. Alzeimer's joins a long list of associated health harms.

This year, we mark World Malaria Day by highlighting communities here in Africa that are winning the battle against this deadly disease. Locally-led programs from Senegal to Kenya to Ethiopia are employing malaria control methods that are safe for human health and environmentally sustainable. And it's working.

Over the past decade, our organizations — based in West and East Africa — have watched as global malaria control efforts focused in on a small handful of tactics: indoor spraying of insecticides, insecticide treated bed nets, treatment of malaria cases and preventative treatment for pregnant women. We've also seen the resulting rise of insecticide resistance in mosquitoes and resistance to drugs in humans, along with worrisome health impacts of the insecticides being used.

This fall's mix of elections and anniversaries has stirred up a hornet's nest of talking heads.

September marks the 50^th anniversary of Rachel Carson’s Silent Spring as California is gearing up for a landmark vote on labeling genetically engineered food in November. The combination appears to be a perfect storm for pesticide-promoting pundits.

This month marks the 50th anniversary of Rachel Carson’s Silent Spring, the book that galvanized an extraordinary cross-section of the American public into what we now call the environmental movement. Fifty years later, her courage, skill and sacrifice still inspire, and her legacy remains the contested terrain of some of our country’s most disabling rituals of political partisanship. Pesticides still function as a kind of litmus test: either you’re for farmers and progress and “sound science,” or you’re in the camp of those reflexively “chemophobic” tree-hugging “environmentalists.” And your loyalties to one or the other of these tribes can be indexed to how you feel about pesticides.

Today, on April 25th, we celebrate World Malaria Day. It’s an opportunity to reflect on a serious disease that still affects far too many of the world’s poor. For Africans like myself, it is also an opportunity to highlight an on-the-ground perspective of how best to control malaria.

We've seen that the most effective strategies don't rely on chemical solutions, but on a comprehensive set of tools like biological control of disease vectors, environmental management, individual protections and public health education.
