Last summer, researchers from Mars Inc. and UC Davis announced the "discovery" of a variety of corn grown in Oaxaca that fixes its own nitrogen through mucus-covered aerial roots. Their study, in the journal PLOS Biology, touched off a debate—in Mexico and beyond—about the effectiveness of global policies designed to safeguard the genetic resources of indigenous communities, according to FERN's latest story, published with Yale Environment 360.

Craig Cox, head of EWG's Midwest office, said 1,683 communities had nitrate levels above 5 milligrams per liter and, when plotted on a map, they "crazily lined up with intensive agriculture."
