<i>Eyewitness: Endangered Animals</i> takes a look at creatures around the world that are currently threatened with extinction, along with the ways that we can help them survive. Starting with an overview of biodiversity and the web of life, the book then examines the threats facing a wide range of species, including polar bears, sea turtles, tree frogs, river dolphins, jaguars, pandas, gibbons, and the California condor.
