Abstract topic of this paper is the problems and solutions of sea otters. It argues that human should learn what happens to sea otters and think of what they can to protect them. There are three reasons for this argument. The first is that human should clean up the oceans easily and economically by collecting the garbage. The second is that humans can get them better and get much more information by investigation. The third is that human should save the garbage and domestic discharge as much as possible.
