Abstract
This paper argues that people should consider the decrease in the population of sea otters. The exact reasons why sea otters are gone have not been discovered. This paper claims that people should strive to protect sea otters from the environmental problems for four reasons. First, the reasons which cause decrease in the population of sea otters can also cause other problems of the ecosystem. The second is that it can be warning to people, and the third is that it could prove the ways to solve other environmental problems. Finally, the environment which was already hurt cannot return.
