Accordingly, are amphibians going extinct?Amphibians have existed on earth for over 300 million years, yet in just the last two decades there have been an alarming number of extinctions, nearly 168 species are believed to have gone extinct and at least 2,469 (43%) more have populations that are declining.Likewise, what are two reasons for the demise of the amphibian populations? Decline in amphibian populations The decline in amphibian populations is an ongoing mass extinction of amphibian species worldwide. Several secondary causes may be involved, including other diseases, habitat destruction and modification, exploitation, pollution, pesticide use, introduced species, and ultraviolet-B radiation (UV-B). In this manner, what percentage of amphibian populations is declining? 3.79 percent per year What specific actions are being taken to help declining amphibian populations?Eat organic food. By reducing pesticide and fertilizer use, you directly help in reducing the amount of chemical contamination that affects many amphibian species. Avoid releasing environmental estrogens into the water. Environmental estrogens are known to affect amphibian worldwide including human being.
