When scientists discuss the Sixth Extinction, they are referring to which pattern in the rate of extinction?
Travka [436]

Explanation:

The Holocene extinction, otherwise referred to as the sixth mass extinction or Anthropocene extinction, is an ongoing extinction event of species during the present Holocene epoch (with the more recent time sometimes called Anthropocene) as a result of human activity.[3][4][5] The included extinctions span numerous families of plants[6] and animals, including mammals, birds, reptiles, amphibians, fishes and invertebrates. With widespread degradation of highly biodiverse habitats such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, or no one has yet discovered their extinction. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates.
