Given enough time, biodiversity will recover. Extinctions create new evolutionary opportunities for the survivors: the blossoming of mammals after the dinosaurs died out ultimately led to our evolution, after all. But the aftermath of this Anthropocene ( 地质史上的新时期，称为“人类世”) extinction will not be like any other. Humans have become the main driving force in evolution--and life will never be the same again.
The list of threats we pose to biodiversity is long. We are killing many creatures directly, destroying habitats, introducing exotic predators and diseases, and pumping out pollution. Already, a tenth o
