Not only Why People should Save Polar Bears but How.

Argument Essay

Try to imagine that two polar bears stand on thin ice; there is nothing surrounding them but sea. They look exhausted and hopeless. Actually, it truly happened in the Arctic. This year, the Daily Mail took a dramatic photo and showed what the plight polar bears face (Mouland, 2007). Furthermore, scientists predicted that the Arctic would lose its ice cover in summer by 2030 (Artic sea ice cover at record low, 2007). All these pointed out that humans should take actions for polar bears immediately

Polar bear is the biggest carnivore, which can be 10 ft tall and 1700 lbs (Mouland, 2007), in the Arctic, and survives by hunting seals. Basically, polar bears rely on the floating ice to move to father place for hunting. Although, polar bear are adjusted to the water and can be swimming the long distance easily, the impact of ice declining is really crashed their lifestyle. In other words, polar bears need to swim longer than before that can delete their energy and make them exposure in danger indirectly. As a result, the melting of sea ice has forced polar bears to become endangered.

Recently, the increased emission of greenhouse gases has accelerated global warming and caused the shrinking of ice caps. Scientists have predicted that the Arctic could have no ice in summer by 2040 (Polar bears on thin ice, 2007). In addition, In Broder’s (2007) article “Warming is seen as wiping out most polar bears” the US government scientists reported that two-thirds of the world’s polar bears will disappear by 2050. One of the reasons is that their habitats are disappearing; another is illegal hunting (Langan, 2007). In brief, polar bears cannot protect themselves, but humans can protect them. As a result, people should save polar bears from extinction.

First, people should slow down the melting of sea ice by decreasing the production of greenhouse gases. Humans should try to find or create a renewable energy to replace unrenewable energies, such as oil and coal, which produce a mass of carbon dioxide when burning. Today, solar energy is being considered as a perfect new energy. Scientists have tried to use solar energy to heat houses or water and have had great successes. In addition, the carbon dioxide production has been rising more than two percent annually (Polar bears on thin ice, 2007). People should cut the emission of carbon dioxide by installing energy-efficient appliances or saving energy, such as taking public transportation or cutting off the power supply of offices at night.

Second, for the long term, illegal hunting is the biggest factor to threaten the polar bear population. Some people, like Inuit and Nunavut, have the tradition of hunting polar bears. For an Inuit hunter, it is not only a preservation of tradition but also a way to create income (Krauss, 2006). There were more than 40 polar bears that had been killed by hunters annually. As a result, many countries, such as Canada and Norway, have made laws to ban illegal hunting. These laws have contributed to protecting the polar bear. In fact, In Canada's eastern Arctic, one of 19 polar bear populations grew to 2,100, up from 850 in the mid-1980s (Langan, 2007). Considering all of the above, people should push all countries to make a law to ban illegal hunting.

Finally, helping polar bears to migrate to the north part from their current habitat is another solution. Although the Arctic has lost its ice cover gradually, the north part of the Arctic still abounds with ice. Recently, the evidence has showed that polar bears have been moving toward the north part (Langan, 2007). People can use advanced technological instruments to help polar bears transplant. Even now, scientists do not have any project about moving polar bear to the Antarctica. In “Job swap” Pond claimed, “polar bears would probably survive in the Antarctic, and the Southern Ocean around it, but they could devastate the native wildlife” (Job swap, 2005). In other words, polar bears can live in other icy environments, but could damage the original species, such as penguins.

Some people claimed we should spend money to help alleviate poverty and get a better life quality instead of saving polar bears. On the one hand, a study has showed that species could adapt to the mild climate change (Bhattacharya, 2004). That is one of the reasons that why the population of polar bears is climbing today in some coastal spots. However, scientists predicted that the Arctic would become an ice free world in summer by 2030 (Arctic sea ice cover at record low, 2007). It is impossible for polar bears to survive in ice-free surroundings. On the other hand, some people claimed that the amount of polar bears is increasing. Nevertheless, according to Langan (2007), “the increase in the population is not a climate-change related issue. It’s the result of conservation and an increase in the harp seal population”. As a result, undoubtedly, polar bear will become extinction in several decades.

In conclusion, global warming is linked to human activities directly. People have the responsibility to take the consequences and to solve the problem. The climate change is not only threatening polar bears but all species. People should try to reduce the greenhouse gases and carbon dioxide in order to cool the Earth and to reserve the ice of the Arctic. Moreover, international countries should promote laws to ban illegal hunting to keep the amount of polar bears. Transplanting is another option that would help the polar bear to move to a suitable environment. However, the melting of the Arctic is progressing. We should not just watch the problem became worse and do nothing. People should take some actions that would save polar bears from extinct immediately.
