WWF: Global wildlife populations down by 50% since 1970

Tigers have gone from 100,000 a century ago to just 3,000

This begs the question: will there be any wildlife left for future generations?

(Reuters) - The world populations of fish, birds, mammals, amphibians and reptiles fell overall by 52 percent between 1970 and 2010, far faster than previously thought, the World Wildlife Fund says.

The conservation group's Living Planet Report, published every two years, said humankind's demands were now 50 percent more than nature can bear, with trees being felled, groundwater pumped and carbon dioxide emitted faster than Earth can recover.

"This damage is not inevitable but a consequence of the way we choose to live," Ken Norris, Director of Science at the Zoological Society of London, said in a statement.
