Wildlife populations around the world have declined nearly 60 percent since the 1970s, with elephants, wolves and salamanders among the creatures affected, a new environmental report warns.
The numbers of mammals, birds, and fish fell by 58 percent between 1970 and 2012 while freshwater species declined by 81 percent during the same time, the World Wildlife Federation (WWF) and the Zoological Society of London (ZSL) said in their The Living Planet report.
