A study published this summer by researchers at the University of Guelph in the Journal of Animal Ecology reports that the use of herbicide-resistant genetically modified (GM) crops are largely responsible for declining monarch butterfly populations. Monarch butterflies rely exclusively on the milkweed plant to lay their eggs and as a food for monarch caterpillars. With increased use of GM corn and soybean crops across the Midwest, herbicides are being applied more liberally, killing milkweed plants and leaving monarchs with few egg-laying sites and food sources. The Organic Center has summarized the findings on its website.
