A new report from the World Wildlife Fund says global wildlife populations are on track to fall by 2/3 by 2020. The Living Planet Report states that mammals, birds, reptiles, amphibians and fish populations declined 58 percent between 1970 and 2012. Animals in lakes, rivers and freshwater systems were hardest hit, declining 81 percent. We analyze the report and discuss what it means for endangered species and conservation efforts.
