Global Warming

At present, with the development of economies around the world may feel that the climate is becoming more and more warmer. CO2 makes up about 70% of the greenhouse gases. It is considered to be one of the greatest reasons of global warming.
It’s very serious, but many people can’t recognize that because the only think about themselves. They don’t mind the climate becoming warmer. They don’t mind the ice melting. They don’t mind how many animals become extinct. They don’t mind how many coastal cities become flooded . They don’t mind……
They are wrong. Global warming can have many strong influences for us. For example:
Global warming will make trouble with physiology. People will become more easily ill and even breed new diseases. People will pay more and more money for health care but more and more people die. No amount of money or even the best doctors, wll not be able to save your life. Even if you aren’t dying, you will feel sad and alone. So many relatives and friends’ death will make you want to kill yourself.
Global warming will give the air and ocean huge power. Thus making large or even super typhoons, hurricanes, tsunamis and other disasters. Many houses will be destroyed. Many place will flood. We will be faced with more and more disasters, damning more and more money and life.
Rising temperatures will not only create higher sea level, but also will cause droughts. Large-scale areas will become arid and thus food production will be less. We will be without food. People around the world will face food
shortages and more and more war will happen for food.
If temperatures continue to rise, animals will come out of hibernation early, but will not have the food supply necessary to survive. For example: Insects will eat a lot of forests and crops with no natural enemies. Without forests, global warming will become more and more sercious, creating a vicious cycle. No crops, means no human food.
The greatest of global warming is at ice age like in the movie “The Day After Tomorrow”, this is a scenario that take place.
So we must do something to avoid these things from happening. First, we should use more and more clean energy and less oil and coal. Second, we should go to work by bus or on foot instead of driving. Third, we should plant more trees. The most important point is we should make a habit of saving energy in everyday life.追问
