Why are frogs important to our environment?

Frogs, as well as salmon and trout, are an indicator species. In the case of frogs, they are largely an indicator species for humans. When frogs disappear or die, it can indicate a threat to humans-- such as a disease or a natural disaster. Also, a large number of breakthroughs in medicine are due to frogs; if frogs die off, we lose a large amount of our medicine. In fact, frogs may be a key factor in curing certain types of cancer.

In short, frogs are extremely important part of our lives-- whether we know it or not.
