Is the biosphere today on the verge of anything like the mass extinctions of the geological past? Could some equivalent of meteorite impacts or dramatic climate change be underway, as humankind's ...

Mass extinctions are defined by the loss of a large part of the biodiversity in a (geologically speaking) short span of time, when the evolution of new species can't compensate the losses.

The sixth mass extinction isn’t a distant threat—it’s happening now. Species are vanishing at an alarming rate due to habitat ...
