The way to protect krill

Abstract
The topic of this paper is the crisis of krill living in Antarctica. It argues that we should protect them because krill is a very useful species to maintain the food chain and ecosystem in Antarctica. There are three ways we can protect krill. The first way is that individuals pay attention to the ecosystem in Antarctica and reduce the pollutants from our lives. The second way is that the government reduces the total amount of pollutants and imposes legal controls on the amount of krill fishing for protecting krill. The third way is that environmentalists and environmental associations investigate and watch the ice shelves and species in Antarctica periodically, let people know about the crisis of krill and Antarctic Ocean and convince the governments and fisheries to reduce the amount of krill fishing.
