1.   It lays out the story of species loss in a particularly clear way, illustrated with incredible photographs.

2.   Pimm believes that with this new calibration of the area-species curve, he and his team have developed a tool for predicting future species losses among endemics.

3.   The relationship of species loss and environmental health is based on the idea that native plants require less pesticides and water, and provide shelter for wildlife.

4.   The theory used to estimate species loss predicts that as an area of habitat is reduced, species will disappear at a predictable rate.

5.   Under the pressure of expanding human population and overexploitation of natural resources, the rate of species loss is expected to accelerate.
