We are clearing this land for timber, grazing land, and buildings. More than three-quarters of all frogs occur in tropical rainforests, which means that most frogs are being evicted from their homes with no place to go. The phenomena of frog deformities, which range from missing eyes to extra limbs, appears to be recent and growing. Many of the deformities have been found in the Midwest, and have scientists baffled. The cause of deformities could be due to climate change, water contaminated with heavy metals or pesticides, an amphibian parasite, or a combination of these things.
Frogs have very thin skin.
They breathe through their skin, as well as through their lungs. What this means is that we should look to frogs for our own well being. If something is wrong in the environment, say a pollutant, chances are that frogs will be among the first affected.
