Working To Save Monarch Butterflies
This year, measurements of the overwintering monarch population in Mexico showed yet another season of decline: Monarchs covered 14.7 percent less acreage in Mexican forests than they did last year. Monarchs have been vanishing—they’ve lost 90 percent of their population since their peak in the 1990s. One of the significant reasons? Monarchs are losing their caterpillars’ main source of food, milkweed, due to increased use of Monsanto’s Roundup. This year, we’ve redoubled our efforts to save monarch butterflies, recently sending more than 30,000 public comments telling the Environmental Protection Agency to ban glyphosate—the main chemical in Roundup.
