What is mass depletions?
Mass depletion is an event in which extinction rates are higher than normal but not high enough to be classified as a mass extinction.
How fast are we losing species to extinction now?
50 times faster than the normal rate!
Is that true The present rate of extinction is normal and about the same as at any other time in the history of the earth?
false

Extinction.
What is background extinctions?
A background extinction is the continuous extinction of individual species caused by climate change, disease, loss of habitat, and competitive disadvantages against other species. Background extinctions occur at a slow rate over time, affecting only a few species at one time.

What are the extinction of animals in the very distant past?
There were five major extinction events in the past. They are called the Cretaceous-Tertiary (or K-T) extinction event, the late Devonian mass extinction, the Permian mass extinction, the Ordovician-Silurian mass extinction and the Triassic-Jurassic mass extinction event.
Is extinction normal?
Extinction is an intrinsic part of the evolution of new species, and is a direct consequence of the forces of natural selection. However, unlike the divergence of species (a process called speciation), one or more species can go extinct at variable rates. For example, marsupial mammals disappeared (from the larger continents)over a long period of time as they lost out to placental mammals. However, most species today disappear at alarmingly rapid rates because of the loss of their habitat.
