Pesticides are killing worker bumblebees vital to plant pollination, according to a recent study in Nature. Two commonly used pesticides, the study found, make bumblebees twice as likely to die and make them less effective at pollen gathering when they don’t die. The study, conducted by scientists at the University of London, helps shed some light on the worldwide decline of the insects, which holds widespread consequences. According to the United Nations, around one-third of all plants eaten by humans depend on pollination from bees. A 2011 report from the U.N. projected that bees and other pollinators are worth about $200 billion to the economy because of the pollination work they do.
