Loss of habitat, climate change and UV radiation are just a few reasons for earths dramatic drop in amphibian's population in the recent years. Amphibians have lived on our earth longer then humans and adapt to a wide variety of habitats over the years. A recent study had proved that human neglect and ignorance has greatly impacted the amphibian population. In the remaining amphibian populations deformities such as extra eyes, or limbs have been reported in as many as 44 states. Some deformities are natural but in some areas up to 60% of amphibians have been reported ta have these defects. Our...
