Dramatic Amphibian Decline
The World

Scientists have identified nearly 6,000 amphibian species, including frogs, toads, and salamanders. 

Amphibians live worldwide but flourish in moist, warm habitats typical of the tropics. 

A recent global study found a staggering 43 percent of amphibian species in decline, mostly because of human influence.

Severe habitat loss and disease have left more species threatened in the Caribbean and Latin America than anywhere else. Columbia alone has 208 species edging toward extinction.

Amphibians’ highly permeable skin is extra sensitive to poor quality environments. Massive amphibian declines are early indicators of damage to Earth’s life-support systems.
