In my lifetime, global wildlife populations have seen an overall decline of more than half. That’s a statement of such enormity that it’s hard to process.
The evidence comes from WWF’s recent Living Planet Report 2018, which shows that, on average, populations of mammals, fish, birds, amphibians, and reptiles declined by 60 percent between 1970 and 2014. And the trends are still going in the wrong direction. My children could be reading about many of these species — such as orangutans and Amur leopards — in history books if conservation actions are not ramped up.
