For article see Metagenomics Mashup. We live in an age of pesticide and antibiotic overuse. One outcome is resistance, increasing pesticide use and contamination and fears that we are entering the “post-antibiotic era”. We are addicted to all sorts of commercial chemicals. So what’s next? How do we break…

[Featured image: http://agriculture.by/blog/photo/igrushki-iz-kartoshki ] By sometime next fall, your side of fries might contain potatoes engineered to resist late blight: the fungus-like disease (caused by Phytophthora infestans) that can cause a once-healthy field to rot in the ground. But rather than turning up our noses at a genetically modified organism, we may want to consider the benefits of blight […]

Dear Mr. Pruitt, I hope you can help me out here. I’ve been having trouble explaining your recent decision in favor of the pesticide chlorpyrifos while dismissing years of work by EPA scientists to my environmental toxicology students. This is a chemical that interferes with the normal processes of the brain causing both acute toxicity – […]

Dear Mr. Pruitt, I imagine there must be some angst these days about Atrazine.  With the 2016 EPA reevaluation concluding that the herbicide isn’t as safe as we all once thought, I am sure growers and consumers are anxious about which way the agency will swing: to ban or not to ban.  Admittedly, back in […]

Dear Mr. Pruitt, With Trump’s proposed budget, looks like you could use some support. We disagree about climate change so I won’t go there, but you have said that cleanup of contaminated sites was a priority, and it looks like hundreds of millions of dollars for haz-waste cleanup could be axed. So, since I’ve been […]

Dear Mr. Pruitt, Last week I wrote to you about DDT. This week let’s consider lead. Like DDT, another jaw-dropper for my environmental toxicology undergrads. You may not remember leaded gasoline. It was phasing out just as you were probably hitting the road. But I do, and I remember feeling good about asking for “unleaded” at […]

Dear Mr. Pruitt, I teach an introductory environmental toxicology class to undergraduate public health majors. Each week we talk about different issues from mercury to DDT and nanomaterials. And each week, inevitably, we talk about the EPA. I am a child of the 1960s, the age when it finally dawned on us that for all the […]
