A.I. "Predator" Drones Can Now Spot and Track Illegal Poachers

Poaching takes a brutal toll on the world's wildlife every year. By the thousands, rhinos are for their horns, elephants for their ivory, and tigers for their bones and exotic pelts. To protect these animals, rangers and conservationists must monitor enormous swaths of land, day and night, looking for poachers who trade on a black market estimated to total $40 billion. It's impossible to stop every poacher. New technology could bolster the efforts of conservationists, though, by putting a set of eyes in the sky.
