Study suggests hundreds of land species near extinction
"The ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilisation, because it is irreversible.
Thousands of populations of critically endangered vertebrate animal species have been lost in a century, indicating that the sixth mass extinction is human caused and accelerating. The acceleration of the extinction crisis is certain because of the still fast growth in human numbers and consumption rates.
In addition, species are links in ecosystems, and, as they fall out, the species they interact with are likely to go also. In the regions where disappearing species are concentrated, regional biodiversity collapses are likely occurring. Our results re-emphasise the extreme urgency of taking massive global actions to save humanity's crucial life-support systems."
