Have you ever seen Polar bears? Maybe you have seen them on television advertisements if you watch television occasionally. I’m talking about Coca-Cola advertisement. There are white polar bears that are drinking Coca-Cola on sea ice. I think not only me but also you want to see polar bears in reality. Actually, they don’t drink Coca-Cola, but their main food is ring seals. They usually live in the North Pole and South Pole. I’m going to talk about the North Pole’s polar bear because all of the data talks about them. Today, they state that polar bears are listed as endangered animals and every year many polar bears are decreasing rapidly. Then, I know why they are declining after I read the articles. “There is a definite link between changes in the sea ice and the welfare of polar bears” (Heilprin, 2007, para. 6). It means if sea ice disappeared, polar bears also go forward to extinction. According to Heilprin (2007), global warming causes a problem by reducing sea ice. It will kill polar bears because they can’t swim continually. Another problem is human activity. Polar bears were almost killed by hunters in the 1990’s (Terhune, 2007). Anyway, Polar bears are one of the important species to maintain, so if they have disappeared, the ecosystem will be broken fast. Diversity of species is very important, because it makes good environmental condition, so the government has to try protect polar bears.
Humans should protect polar bears, because it is possible for them to do. The government and people have to do something by reducing carbon dioxide and greenhouse gases to preserve polar bears’ habitat, making habitats for polar bears such as zoo, and banning human’s destruction. In those ways, we should try to help and protect them.
First, humans should reduce carbon dioxide and greenhouse gases to protect Polar bears’ habitat, because those gases are directly related with polar bears’ extinction. First of all, those gases cause global warming, so sea ice is melted. Then, polar bears lose their habitat. Next, those gases also bring problems, not only for polar bears but also for humans, because all organisms are related with each other. For instance, if polar bears are extinct, sea ecosystem is destroyed, and then it makes humans worse. Finally, polar bears only live in polar regions because they can’t swim for a long time. It’s a big problem because the polar area is disappearing now. Actually, many polar bears are dead or rescued every year. Carbon dioxide and greenhouse gases are mostly from humans, so we can help polar bears directly if we try to do this. Therefore, we should try to reduce those gases, and the government should encourage people to do that, especially encouraging public transportation.
Second, the government has to make habitats for polar bears. First, the government should help to make places at the zoo to take care of polar bears, because cost to make places for polar bears is too expensive. It is good not only for polar bear but also for humans, because people can see real polar bears. Then, when we rescue polar bears that are in danger, we need a place for them. Only government can make professional place easily. It’s a big deal for an individual. Also, polar region is so small for polar bears because sea ice is melting rapidly. If we don’t make a place for them, they will face a shortage of food. Thus, the government has to make a shelter for polar bears and people also should help government to pursue it without problems.
Third, the government should protect polar bears from humans. I think human is the most important factor to threaten polar bears. For example, in the 1990’s, many hunters killed polar bears, so they were in danger of extinction (Terhune, 2007). Also, some people think that economy is more important than environment, so there are so many rash developments to kill polar bears. For instance, people break sea ice just for their business, especially to get water and to make a sea route. The last thing is prohibiting human’s activity right now. Today, the government can control citizens, so they have to prohibit rash hunts and developments. If the government tries to prevent that, the positive result will break out soon.
My opponents argue that this extinction crisis of polar bears is a natural phenomenon. They also say that greenhouse effect isn’t dangerous and it’s natural with short-term records. However, it will cause bad results and it’s not natural but clearly destruction of ecosystem. Polar bears occupy big parts of ecosystem, so if they are disappeared, many other species can get critical damage. Then, greenhouse effect will destroy the Arctic sea ice and polar bears will be dead. Then, it also causes many big problems, even if it affects humans. Actually, the sea level rising is one of the biggest problems. It can hurt human directly. Although it looks like a natural situation, it’s a very serious problem. “Only a third of the world’s polar bears may be left within 50 years because of thinning ice from global warming in the Arctic” (Heilprin, 2007, par. 1). It’s too fast reduction, and Polar bears’ reduction is related with many things. Therefore, the government and people should try to make sense of this dangerous situation. Then, we have to make moderate methods to protect them.
In conclusion, humans have to know how it is dangerous and try to protect polar bears with those three ways. In other words, we save polar energy by decreasing harmful gases such as carbon dioxide and greenhouse gases, establishing habitats for polar bears, and prohibiting human’s rash developments. As a result, we have to protect polar bear in danger if we don’t want to make big problems. Also, we should try to make other methods to protect polar bears continually. It’s not only for polar bears but also for human. Of course, I don’t know what results will come, butwe have to try many ways to save polar bears
