Study says wildlife populations fell 58 percent in 40 years –

A new analysis by the World Wildlife Fund and the Zoological Society of London says worldwide, wildlife numbers plummeted by 58 percent between 1970 and 2012—and the losses are on track to reach 67 percent by 2020. Logging, poaching, overfishing, pollution, and destruction of habitat for agriculture were the major causes of the population collapses. While some researchers have concerns about the report’s methodology, they agree with the overall message. The Guardian
