OVER A QUARTER OF WORLD'S WILDLIFE GONE
Between a quarter and a third of the world's wildlife has been lost since 1970, according to data compiled by the Zoological Society of London, reports the BBC.
The Society says populations of land-based species fell by 25%, marine ones by 28% and freshwater ones by 29%, and that humans are wiping out about 1% of all other species every year--that one of the "great extinction episodes" in the Earth's history is under way.
