From the book: ""It's on our watch that amphibians are checking out. I think we ought to be very concerned about that."" Frogs are found everywhere: from the tropics to north of the Arctic Circle, from the heights of the Himalayan Mountains to the driest deserts. Frogs live on every continent except Antarctica. They live part of their lives in water and part on land. Frogs absorb moisture and even breathe through their skin. Unfortunately, their skin is also super-absorbent to deadly pollutants and their eggs are thin, jellylike bubbles that absorb waterborne pollutants. Consequently, frogs are "first indicators" of air, water and land pollutants, acting as a barometer for measuring the health of the environment. As such, they provide a valuable warning about our future if toxic elements continue to be released into the air, soil and water. Frog Rescue profiles the disappearance and endangerment of frogs around the world. The book also covers a range of innovative programs used around the world to protect this vulnerable species. Some of the frog species included are: Australian frogs that rear their young in their stomachs Poison dart frogs Costa Rican golden toads.
