Earth has lost half of its wildlife in the past 40 years, says WWF

The number of wild animals on Earth has halved in the past 40 years, according to a new analysis. Creatures across land, rivers and the seas are being decimated as humans kill them for food in unsustainable numbers, while polluting or destroying their habitats, the research by scientists at WWF and the Zoological Society of London found.

“If half the animals died in London zoo next week it would be front page news,” said Professor Ken Norris, ZSL’s director of science. “But that is happening in the great outdoors. This damage is not inevitable but a consequence of the way we choose to live.” He said nature, which provides food and clean water and air, was essential for human wellbeing.

“We have lost one half of the animal population and knowing this is driven by human consumption, this is clearly a call to arms and we must act now,” said Mike Barratt, director of science and policy at WWF. He said more of the Earth must be protected from development and deforestation, while food and energy had to be produced sustainably.
