Stopping Elephant & Rhino Poachers

More than 20,000 elephants were killed by poachers in 2014, according to the Convention on International Trade in Endangered Species (CITES). Nearly 1,300 rhinos were poached on the continent last year, according to the World Wildlife Fund.

A group called Air Shepherd hopes to stop the longtime problem of poaching by using computer-controlled drones that spot poachers and make it easier for rangers to find them across Africa's massive landscape.

The drones can monitor a lot more ground than rangers. Computer data tell the drones where to fly. The computers process data to predict where the animals will be each night. And where there are elephants and rhinos, there are often poachers.
