Like a Disney movie gone horribly wrong, the U.S. Department of Agriculture just airdropped 2,000 mice attached to tiny cardboard parachutes into Guam. The mice are dead and contain a key ingredient: painkillers. The objective: bring down invasive brown tree snakes that have all but taken over.
Brown tree snakes have been a scourge of the U.S. territory since arriving there during the 1940s to 1950s, probably on cargo ships. They snack on native birds and lizards, and have caused several species to go extinct. They also mess with electric substations, triggering annual power outages, according to the U.S. Department of Agriculture.
