UN warns of worst mass extinctions for 65m years
`Humans have provoked the worst spate of extinctions since the dinosaurs were wiped out 65m years ago, according to a UN report that calls for unprecedented worldwide efforts to address the slide.
The report paints a grim picture of life on earth, with declining numbers of plants, animals, insects and birds across the globe, and warns that the current extinction rate is up to 1,000 times faster than in the past. Some 844 animals and plants are known to have disappeared in the last 500 years.’
