Climate is changing

The author, Will Iledale, explains the environment problem using the example, polar bears, in the “Polar bears drown as ice shelf melts.” Polar bears are dying and their population fell because recently the climate of the Earth is changing. Summer temperatures have increased in Alaska, and the Arctic ice shelf is melting. As a result, polar bears drown. And the rate will be more increased in the future.

Nowadays, the environment of the Earth is noticed in the world. There are many problem in our world, for example, global warming, desertification, ozone depletion, acid rain, and garbage, etc. I think if the climate change; as it is now, we will die like the polar bears. I think global warming, desertification and ozone depletion are the most serious problems which we have to solve, so I would like to talk about the environment problem of the Earth using the three examples next.

First, we should do something to contorol global warming. I think this is the most serious problem. Nowadays the temperature is increasing because CO2 rates are rising and forests are cut down. When we use cars and make some things in the factory we have to make exhaust, CO2. Today we can’t live without car and industry. Also, we need trees to make paper or house or some things, but trees assimilate CO2 and create O2 (oxygen), so the CO2 level is increasing because forests which assimilate CO2 essentially are decreasing. And the global warming might be the cause of the other environment problems.

Second, we should consider desertification. This is one of the results of global warming. The increasing of temperature and cutting down of forests promote desertification. Conversely, desertification promotes global warming. Thus there is a synergism between these problems.

Third is ozone depletion. Ultraviolet rays can come in the Earth directly through the ozone hole. And Ultraviolet rays are the cause of skin cancer. Actually, it is very serious problem in Australia. Australians can’t go out of the house without clothes when Ultraviolet rays are strong. I think this kind of disease will increase if we can’t solve the environment problem.

In conclusion, one problem makes many troubles. I think the industry which helps us will be the cause of death. Therefore we should think what matter is the most serious problem again. And we should use the developed new technology for climate problems. I hope we solve these problem and make the Earth a very comfortable place for every living thing.
