Given the growing human population, it is difficult to imagine a complete stop to habitat destruction. However, biologist Norman Myers and his collaborators have concluded that twenty-five biodiversity “hotspots,” making up less than two percent of Earth’s surface, contain up to fifty percent of all mammal, bird, reptile, amphibian, and plant species. Hotspots occur in areas of the globe where favorable climate conditions lead to (A)(high) levels of plant production, such as rain forests, and where geological factors have resulted in the (B)(isolation) of species groups, allowing them to diversify. Stopping habitat destruction in these hotspots could greatly reduce the global extinction rate. Of course, preserving these biodiversity hotspots is not easy, but by focusing conservation efforts on hotspot areas at the greatest risk, humans can very quickly prevent the loss of a large number of species.
