Earth’s Early Warning System Amphibians Earth’s Early Warning System

Brief Biology Amphibians are metamorphic. Amphibians rely on water to reproduce. Amphibians are cold-blooded They breathe through their skin when the lack lungs

Chemical Pollution Amphibians absorb oxygen through their skin. Their skin is permeable. They are very sensitive to contaminants. Most reactions to chemicals are obvious.

Air Pollution Being ectothermic, temperature changes can be detrimental. UV Radiation may slow the development and increase the mortality rate of amphibian eggs.
