I know I've written it before, but we're really witnessing the endgame for endosulfan in Geneva this week. I'm here, once again, for negotiations under the Stockholm Convention, otherwise known as the POPS treaty. The global agreement bans the worst of the worst chemicals — Persistent Organic Pollutants like dioxins and PCBs. As I've been chronicling in this blog, endosulfan has been winding its way through the Convention's evaluation process for several years now. If the stars align, it'll finally be added to the Convention this week, triggering a global phaseout.

At Pesticide Action Network, we mark Earth Day by reflecting on the work handed to us by our predecessors. We take stock of their predictions for our world, and pull lessons for moving forward.

I am reminded, in particular, of Rachel Carson's articulate science and clarion call on pesticides in Silent Spring. Of Cesar Chavez and the United Farm Workers, and how their very first contracts demanded the decreased use of pesticides. Of farmers and eaters who have grown and harvested foods for millenia while protecting biodiversity and our earth. And of my own populist, upper Midwest heritage, and how the Wisconsinite Earth Day founders mobilized broad and diverse support for stewardship, 20 million strong in 1970, that led to some of the most important policies that safeguard our collective nest.

Earlier this year, the U.S. Department of Agriculture (USDA) shocked the American public with its hasty approval of three highly controversial GE crops in a row (alfalfa, sugar beets and ethanol corn). In doing so, the agency effectively thumbed its nose at U.S. federal courts and spit in the face of consumers and farmers alike. Now, USDA has apparently decided that getting sued for ignoring U.S. environmental laws is getting to be too much of a hassle. So they've come up with a new plan: why not let Monsanto evaluate the potential harms of its new transgenic products? It’ll be so much quicker this way. And save USDA a lot of money.

The two-year pilot program allowing GE developers to conduct their own environmental assessments for USDA is an “experiment” to improve its systems, says USDA. Tom Philpott calls it a craven way out.

Editor's note: This week, Environmental Health Perspectives selected this trio of studies for its 2012 "Paper of the year" award. EHP notes that the importance of the research to understanding the "alterations of cognitive function following developmental exposure to environmental chemicals." Congratulations to the study authors from all of us at PAN. We are reposting our original coverage of these studies below.

School-age children have lower IQs when their mother's are exposed to pesticides during pregnancy. This is the conclusion of 3 independent studies released today in the journal Environmental Health Perspectives.

Earlier this month in Rome, the deadly pesticide paraquat moved a step closer to global phaseout. Paraquat is widely known in the developing world as the poison of choice for farmer suicides, and was notorious in the 1970s as the herbicide sprayed by the U.S. government to try to eradicate marijuana plots in Mexico.
