The World Wildlife Fund released a stunning report this week: From 1970 to 2010, overall vertebrate animal populations declined by half. It’s our fault.
To be clear: It’s not that half of all species have been made extinct in the past half century. It’s that overall population counts for vertebrate species (besides humans) have declined by half.
Why are population numbers dropping so quickly and drastically? The primary reasons are exploitation (read: hunting and fishing, 37 percent) and habitat loss (31.4 percent). All of which means we should prepare to say goodbye to more and more amazing animals — like African forest elephants, whose populations have declined by 60 percent since 2002.
The WWF team measured more than 10,000 species over 40 years, and they found an overall declining trend in 52 percent bird, fish, reptile and amphibian, and mammal populations. Of those freshwater fish, frogs, and shorebirds had it the worst:
In the study, the WWF includes some hundred or so pages of advice on how to save the quickly dying species of the world. They recommend completely changing the way the world works ( “redirect financial flows,” “produce better,” create “equitable resource governance”).

Extinctions now 1,000 times faster than before humans. Humans may be causing mass extinction comparable to major meteor impacts. http://www.cbc.ca/news/technology/extinctions-now-1-000-times-faster-than-before-humans-1.2658571
