We need amphibians. Humans have discovered antibiotic and anti-tumor properties, analgesics, anti-inflammatory compounds, and natural adhesives from amphibians. We have used them to learn anatomy and for medical research and tests. And amphibians have been important cultural symbols around the world and throughout history.
However, amphibians such as frogs and toads have semi-permeable skin that makes them especially sensitive to changes in their environment. As many amphibians utilize both aquatic and terrestrial habitats during their life cycles, these vulnerable creatures are among the first to suffer the consequences of environmental threats such as pollution, destruction of wetlands and other habitats, non-native species introduction, and increased ultraviolet radiation. More than 2,000 amphibian species from around the world are currently threatened with extinction. As an indicator of greater ecosystem health, this widespread trend raises many concerns about the health of our environment.
