This year’s report found that, on average, populations of mammals, birds, fish reptiles and amphibians have declined by 60 percent from 1970 to 2014. The conservation nonprofit has published its Living Planet Report every two years since 1998. The “60 percent” figure does not mean that 60 percent of wildlife species have gone extinct. Instead, the number represents the average drop in population sizes, not the drop of the total number of animals. Taken together, that would be an average population drop of 60 percent.
