Document Summary
Conservation: the science concerned with increasing the probability that the earth"s species and communities will persist into the future. A collective title given to the various actions we can take to slow down/reverse the losses of species and of biodiversity. Species may become extinct (locally or globally); they may migrate to new areas. Presently, rates of extinction greatly exceed those of species creation or immigration: species are being lost, and we are witnessing a decline in biodiversity. At a larger scale we may include the variety of community types present in a region swamps, deserts, woodland succession, etc: biodiversity has a range of meanings. Sometimes conservation efforts are focused on an individual species, where as other times it is explicitly focused on entire habitats. The aim is to reverse a past failure to conserve. Considerable uncertainties in our estimates of all three. The number of species in the world is much larger than what we estimate.
