Humans Fuel Worst Extinction Since End of Dinosaurs

You know when the Associated Press is writing these sorts of headlines -- and believe me when I say I respect the AP even though they aren't exactly a bastion of incisive, detailed coverage -- something must be seriously amiss. An excerpt:

Changes to Earth's biodiversity have occurred more rapidly in the past 50 years than at any time in human history, creating a species loss greater than anything since a major asteroid impact wiped out the dinosaurs.

That's the conclusion of Global Biodiversity Outlook 2, a report released today by the United Nation's Convention on Biological Diversity.

"In effect, we are currently responsible for the sixth major extinction event in the history of the Earth, and the greatest since the dinosaurs disappeared, 65 million years ago," the report states.
