Do you think global warming is a serious threat to our envirnment??

There are several reasons why global warming threat to us. These include rising sea level, unusual weather. First, I would like to tell about rising sea level. The effects of this cause serious problem to us. For example, the people who live in coast line have to move out because if sea level rises, their city will sink under water. Why is this problem occurring? This problem occurs because of global warming. If temperature rises, the ice at South and North Pole melt. And then the amount of sea water increase. econd, it is unusual weather which is caused by global warming. Nowadays you can tell that climate is changing little by little. For example, rain start at a sudden. Or temperature is getting warmer and warmer. As a result of this problem, plants which you have never seen in your country grow up in your garden or you can see insect which you have never seen. Some people might think it is not matter. Because we can enjoy another kind of plant. But it is not good. If ecosystem changes, you can’t watch native insect or plants. Don’t you think it’s a sad thing? You grew up such a circumstance. Thus maybe you can’t watch same environment in your home town. In addition to this fact, there is another problem. It is shortage of food.
