Like any parent, when I drop off my kids at school, I want to trust they'll be safe. Safe from violence, safe from bullying, safe from diseases and pests — and safe from pesticides that can cause them harm.

As evidence continues to pile up that pesticides can harm children's health and development, many schools are finding ways to control pests on school grounds without spraying dangerous chemicals. A new report from our coalition partners, Californians for Pesticide Reform (CPR), outlines the scope of the problem, the most innovative solutions, and ways parents and policymakers alike can help get pesticides out of school buildings and playgrounds.

Geneva, April 29: I am extremely pleased to report that the Parties to the Stockholm Convention have just agreed to phase out endosulfan globally! This is a huge victory for PAN and our partners around the world, most especially our civil society colleagues in India who have worked tirelessly to make this happen.

The final decision has a few loopholes (they almost always do), allowing endosulfan to be used on certain crops against some specific pests for the next six years. But we’re nonetheless very happy, and I’m certainly relieved. The loopholes (“specific exemptions” in the language of the treaty) were a necessary, if unfortunate, compromise needed to get India to agree to the ban. Still, most uses will end next summer, with a short list winding down through 2017. And then that’s it: no more endosulfan.

New tests conducted by British scientists show that widely used agricultural pesticides disrupt male hormones, and may be contributing to a suite of reproductive disorders increasingly common among men.

Reduced sperm count, infertility and abnormal genitals are among the problems some scientists have dubbed “testicular dysgenesis syndrome.” This latest study greatly strengthens the evidence that these problems may be linked to environmental contaminants.

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.
