We’ve lost more than half the world’s wildlife since 1970

Wildlife populations around the world have declined by more than half since the 1970s, with elephants, wolves and salamanders among the creatures affected, and human activity is largely to blame, a new environmental report warns.

The numbers of mammals, birds and fish fell an average of 58% between 1970 and 2012, the World Wildlife Federation (WWF) and the Zoological Society of London (ZSL) said in The Living Planet report published Thursday.

Ken Norris, director of science at ZSL, said human behavior continues to drive the decline, particularly in freshwater habitats.
