Global Warming Threatens Polar Bears

The article “Polar Bears and Conservation” states polar bears are living in the Arctic area of the earth, and their lives are threatened. Biologists estimate their population as only 20,000 to 25,000. There are a few to reasons to explain decreasing of polar bear’s population. Non-sustainable harvest of polar bear by Nunavut has caused the declining of their population, and the change of the ice habitat, too. The most serious fact that threatens polar bears is climate change. Ice pack diminishing causes the loss of their hunting areas. As a result, the polar bear nations agreed to protect the bears by prohibiting random harvest, sharing their research, and organizing the Polar Bear Specialist Group at Oslo.

The polar bear is a very familiar animal; its plain white hairs and cute face give her a favorable look. Polar bears live in the arctic area, and they hunt for prey. Lately, polar bear’s population is decreasing due to global warming; only 20,000 to 25,000 polar bears live on the earth now. As global warming accelerates, polar bears’ lives are threatened. We have to change our attitudes toward them, and international institutes and the governments have to regulate people in order to save polar bears.

First, people have to realize their global warming is really a serious problem, and it threatens animals such as the polar bear. Some people think global warming is just the warming up of the earth, but it is not true. Global warming affects environment around the world; this means it can affect humans. We have to realize how serious it is.

Moreover, international institutes and the governments have to set more powerful laws. A refrigerator needs freon for its cooling. Advanced countries use substituted material, but few countries still use freon in a refrigerators. Freon makes holes in the ozone layer. As a result, stronger sunlight comes through the holes and accelerates global warming. This action causes melting down of ice packs. It makes the habitat of polar bears smaller. In addition, polar bear’s main prey is fur seals and seals. As the period of freezing shortens, polar bears have to suffer from hunger. We need actions on the internal and governmental levels.

Finally, we should love the environment and keep it. Global warming delivers extermination of polar bears, other animals, and our society. If we hadn’t tried to ignore this situation, and we were willing to save animals in the world, it couldn’t happen. We made the problems, so we have to solve them.
In conclusion, we already know the solution, but we just don’t do it. We must have a wider view; it is not only the polar bear’s problem but also the problem we will have in the future.
