Nowadays, much carbon dioxide is one of the worst problems affecting the environment all over the world. It has happened from factories, cars, etc... The more comfortable our life, the more worse the environment. Because they use a lot of energy, they produce lots of carbon dioxide. Also much carbon dioxide is able to be arisen some problems.
First, it is the global warming, which means temperature is higher than before in the world. Because it roles greenhouse gas, which means this environment is hard to go down the temperature, temperature is higher and higher.
Second, sea level has been rising because of global warming. Because temperature is higher and higher, frozen continents like Antarctica melt into sea. Therefore, it happens that.
It is so difficult to solve them because there are many countries want to develop own country. Therefore, they use a lot of energy so we can’t stop it. However, some countries concluded a treaty about it in 1997. It was object to reduce carbon dioxide in each country. Unfortunately, some countries don’t achieve it.
I think we can’t change our country but we can change our life. For example, when I go to play with my friends, I often use car because I can get various places easily. However, I should use train because it doesn’t exhaust carbon dioxide. It is good for the earth. In addition, I would like to buy an Eco car like a hybrid or an electric car in the future because I don’t want to destroy our world. These actions may not have power but it is better to do than never, I think. I also hope it solves in the future.
