Polar bears drown as ice shelf melts
Practice Article
According to Iredale in “Polar bears drown as ice shelf melts” that many polar bears have drowned because of abnormal climate change. In Alaska, average summer temperatures have kept increasing by 2~3C degrees since the1950s. Presently, lots of researchers, who investigate polar bears, tell us many polar bears are dying, and expect that they are going to be killed by lack of food. In fact, there are many sources of food for polar bears, but they could not find their food since the climate changed abnormally. Therefore, they had to compete with each other to get food, or they had to leave to another place, which has lots of sources. Some polar bears, which left to finding food, could be dying when they met rough seas, unfortunately, even though they are good at swimming on the sea. Finally, many polar bears fell into serious problems of existence.
In fact, it is obvious that we are falling into terrible problems of nature pollution. I am going to relate what the problems of polar bears are, and how we could solve these problems for polar bears in Alaska.
First, one kind of pollution is air pollution. After the industrial revolution, the climate has changed into a strange situation in the world because of toxic substances like freon gas. Freon gas is very useful to our life as it is used in a spray or air conditioning. In summer, we have to turn on the air conditioner to avoid hot weather. The cool wind of the air conditioner is made by freon gas. While the air conditioner is working, it will make lots of freon gas, and then this freon gas will destroy the Ozone layer. Actually, it is really a serious problem presently.
Second, the climate will increase in degree by because of the destroying of the Ozone layer. And now, it is the truth that the North Pole is melting. Therefore, many polar bears are fighting other bears or leaving the North Pole to get food, or some polar bears are dying.
Third, actually it is not only problems for the polar bears, but also for us. We have to find a solution, because it is possible that we are going to lose our land if all parts of the North Pole are melted by the hot weather. Also, if the Ozone layer is destroyed, ultraviolet rays will fall down on the land and then we might get a disease of the skin. In fact, many countries are trying to use other resources such as electric power, waterpower, and wind power instead of freon gas. Also, many governments already made the law, regulating to use Freon gas. If we use crude resources for something, we cannot only protect polar bears but also ourselves.
In conclusion, lots of polar bears have fallen into the serious problems presently because of the strange changing climate. Because of our mistaking about using freon gas, the temperature of the climate is increasing and the North Pole is melting. Therefore, many polar bears have lost their ground and food, so they are in crisis. I think that polar bears are the first victims, and the second victims will be us.
