I go along with "JUNK SCIENCE". 

The authors describe the shrinking population of species as “a massive erosion of the greatest biological diversity in the history of Earth.” 
On a happier note, scientists point to ongoing efforts to save endangered species and their habitats.
So which is it the extinction of species or the saving endangered species? In either case it's man fault. So if man pays his of her carbon tax, lowers his or her standard of living, and tax business for their carbon usage, that will stop the extinction of animal species?
