How do species become extinct affect the biosphere?
As species become extinct, the variety of species in the biosphere decreases, which decreases the health of the biosphere. Biodiversity is the variety of life in an area that is determined by the number of different species in that area. Biodiversity increases the stability of an ecosystem and contributes to the health of the biosphere.

What is the best measure of biodiversity?
