Description

The world's biodiversity is in serious decline. We do not know the total number of species that were on this planet, say, at the beginning of the second millennium, but by the beginning of the third, we have identified 1.4 million species and we think there are at least 20 million, based upon individual studies of trees in rain forest for example and estimates of ecosystem diversity. How can we measure the usefulness of species to us and how many of them do we need to maintain the biosphere sustainably?
