From our friends at Iowa Watch: Iowa’s wide expanses of row-cropped fields produced roughly 2.5 billion bushels of corn and 554 million bushels of soybeans in 2015. And for many, those high yields are thanks in part to pesticides. But what impact, if any, do those chemicals have on our health? It’s a controversial topic and the answer is hard to pin down. In many cases, those we spoke with said the jury is still out.
