The current culmination of human effect and climate change is a greatly amplified version of the events that caused extinctions of large mammals such as the wooly mammoth in the Pleistocene era. Current calculations, using the modest estimate of 10 million species in the world, predict that 1 million species are at risk for extinctions due to changing conditions. Currently, the world's biologically unique environments have lost 70% of their high quality habitat.
These extinctions relation to environmental science for many reasons. Primarily, the loss of species will directly effect their environments because food sources and/or predators will be lost, causing shifts in food webs and balances. Also, the synergy effect may take place and add the changing climate, human impacts, and species loss into an even greater change than expected, creating massive shifts within the environment.
Is there any way to reverse the effects of species loss once they have occurred?
