Map Description:
Some 5,000 species of amphibians inhabit the world, mostly frogs, toads, and salamanders, and they seem to be dying at unprecedented rates. This situation has raised alarm because amphibians are widely regarded as uniquely sensitive indicators of the planet's health. Much of the damage to amphibians comes from habitat destruction, particularly the draining of wetlands, but what has scientists particularly worried are the declines and apparent extinctions in areas far removed from obivous human intrusion.
