关于此电子书
Frogs are very sensitive to their environment. Changes in their appearance—and their rapid disappearance—can tell us when the environment is unhealthy. When people around the world began noticing that frog species were dying or becoming deformed at an alarming rate, they knew something had to be done. Frogs in Danger gives an overview of some of the frog species that have become endangered and why. Read about a flesh-eating fungus that thrives in warm climate and on the skin of frogs. Find out what scientists—and kids in their own backyards—can do to help these indicators of Earth’s health.
