Extinction rates are now
100 to 1000 time above normal or background levels
times above normal, or background, levels.
Studies of biodiversity suggest that human-induced extinctions will rival the great mass extinctions of prehistory, including the one that wiped out the large dinosaurs.
Biodiversity hotspots, mapped by Conservation International, are the richest and most threatened reservoirs of natural diversity. They cover only 2.3 percent of the world's land yet contain a high number of plant and animal species. For instance, the Hawaiian islands are rich in diversity but are particularly vulnerable to extinctions caused by the introduction of non-native plants and animals. According to the American Bird Conservancy, 71 of Hawaii's endemic bird species are already extinct; only 31 species remain.
