The Earth's Sixth Mass Extinction under way

Biological Annihilation: Earth's Sixth Mass Extinction Event is Under Way

Earth is entering its sixth mass extinction event, posing a "frightening assault on the foundations of human civilization," says a new study co-authored by Professor Gerardo Ceballos at the University of Mexico Donald

Ongoing mass extinction causing ‘biological annihilation,’ new study says

• Building on research in which they showed that two species have gone extinct per year over the past century, a team of biologists analyzed the population trends for 27,600 vertebrates around the world.
• They found that nearly a third of the animals they looked at were on the decline.
• In a closer look at 177 well-studied mammals, the team found that all had lost 30 percent or more of their home ranges, and 40 percent had lost at least 80 percent of their habitat

This is the paper by Ceballos and Ehrlich

Biological extinction via the ongoing sixth mass extinction signalled by vertebrate population losses and decline
