A new artificial intelligence tool could be the key to saving lives and reducing conflict between people and the decreasing populations of endangered Asian and African elephants. African elephant populations have dropped from 12 million to 400,000 in the past century, according to the World Wide Fund For Nature (WWF). There are also now fewer than 50,000 Asian elephants left in existence, according to WWF estimates. The gentle mammals face an onslaught of threats, from the illegal ivory trade to deforestation, which has forced the elephants to expand into human-inhabited areas and has increased conflict with people. Farmers worldwide -- including in India, Thailand, and Africa -- have frequently reported negative interactions with elephants grazing on crops or entering villages.
