are the leading suspected cause of frog mutation and decline in their population. There are many smaller factors that go hand in hand with one another are caused specifically because of our actions‚ even though they do not directly cause these results they help speed up the process. As a first thought most people‚ as I did‚ would point out that the sole cause of this issue was the chemicals. In addition to the direct effects of chemical contaminations on frogs‚ human activities are to blame for
