Abstract
The topic of this paper is importance of krill. It argues about whether global warming, which is the cause of decreasing of krill, is an important problem or not. First of all, I deal with solutions. There are two causes of global warming and three solutions of global warming. First is individual endeavor and second is government endeavor. And last is ban of intensive fishing. I'll introduce opponents of protecting krill and then I'll argue this opinion. Last, it is conclusion. I'll summarize my thesis.

They are tiny but live in massive underwater swarms. They make salmon flesh red. Humpback whales eat them by the ton. They are shrimp-like creatures “that scientists say are the ocean’s fundamental food source” (CBS News, 2006). “And since krill are a vital part of the aquatic food chain-they are the diet of everything from fish and seabirds to giant baleen whales” (CBS News, 2006). In this way, krill plays an important role in the ecosystem. But it is a big problem that the number of krill is decreasing, nowadays.

So there are many problems. The first is it that damages our ecosystem. And krill can remove carbon dioxide from the ocean, so if krill is decreasing, carbon dioxide will increase in the world. And there are two reasons they are decreasing. First is global warming, because their habitat is in the Antarctic, but the melting of ice because of warming disturbs their habitat. And second is intensive fishing. Krill’s demand is increasing now, so many people are fishing them; as a result the number of krill is decreasing.

Krill plays an important role in our ecosystem. So we shouldn’t ignore decreasing of krill, and we should try to find a solution to solve the problem. “Mankind has the power to destroy the planet; we have the power to save it” (Sharing the planet, 2007). To solve the problem of global warming, first of all, we need an individual endeavor, for example, turn your lights off, “turn your lights off, turn your T.V. off, walk to the shop, and buy a greener car” (Waller, 2007). And there are 5 detailed ways. First is to act collectively; acting individually is not enough to solve this problem of global warming. The reason is global warming is too big and global a problem to solve with individual endeavor. “We must bring pressure to bear on power holders and decision makers in government to promptly and decisively act on the national and international levels to curb greenhouse gas emissions” (Sharing the planet, 2007). And second is “keep your car inflated. Check them monthly. Save 250 lbs. of carbon dioxide and $840 per year” (Sharing the planet, 2007). Third is use recycled paper; “make sure your printer paper is 100% post consumer recycled paper. Save 5 lbs. of carbon dioxide per ream of paper” (Sharing the planet, 2007). Fourth is buy products locally; “buy locally and reduce the amount of energy required to drive your products to your store. The consumable products we all purchase represent over half of the average family’s carbon footprint! “(Sharing the planet, 2007). Last is buy a fuel efficient car; by buying an efficient car, we can save money and save many resources.

To solve the problem of global warming, we need not only individual endeavor but also government endeavor. So we need our government’s participation; for example, “implement emergency laws, use the power of the media to influence those who are not aware or are too stubborn or selfish to do anything about it” (Waller, 2007). And also government should accept experts’ opinion to solve global warming and keep krill. The first which is one popular geoengineering scenario, is to create an artificial volcano. Thomas Wigley, an expert on climate change based at the National Center for Atmospheric Research in Boulder, Colo., has created computer simulations that replicate the 1991 “Mount Pitnatubo effect – a temporary cooling period created by the launch of 20 million tons of sulfur dioxide into the stratosphere” (Trivedi, 2008). And “another plan is to create artificial trees that extract carbon dioxide directly from the atmosphere” (Trivedi, 2008).
“Our concern is that a targeted krill fishery would threaten the health of the region’s fishing economy and culture” (CBS News, 2006). So we should protect krill from overfishing. To keep from intensive fishing, the role of government and the participation of other countries are important because it is global problem. “The Pacific Fishery Management Council, an advisory board to the Nation Marine Fisheries Service, approved the krill harvest ban” (CBS News, 2006). And also now that “the council has proposed a federal ban, Ben Entricknap, a spokesman for the environment group Oceana, said they’ll move to extend the ban to all U.S. water”(CBS News, 2006).

Opponents of protecting krill say that it is not effective because of the cost of keeping them is too expensive. So Driscoll said “main problem is that cost of limiting greenhouse gas emission could be much higher than the costs of phasing out CFCs, for developed and developing countries alike” (1997). But the most important thing is keeping krill and preventing global warming. Because the continuance of global warming makes a bigger problem than they imagine, we should solve this problem now. And also we don’t have to worry about cost. According to this article, “costs of reducing emission will decline with technology advances in areas such as renewable energy” (Driscoll, 1997).

It looks like a little problem that krill is decreasing. But, it causes many problems; it damages our ecosystem and threatens human life. So we should know the cause of decreasing of krill and try to keep krill. For those reasons, we should protect global warming, because global warming makes a decrease of krill. To prevent global warming should prohibit intensive fishing because overfishing is causing the decreasing of krill. To prevent global warming, individual, government and other countries’ endeavor are very important. Opponents of krill keeping krill say that global warming isn’t big problem and protecting krill is too expensive. But krill is important in the ecosystem and human life, so we should keep and protect them.
