With the development of economy，more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases，which is considered to be one of the greatest causes of global warming. It has harmful effects，causing the sea level to rise and many natural disasters to strike.

So we must take effective measures to save our planet. First，we should use more clean energy and less coal and oil. Second，we should go to work on foot or by bus instead of driving a car if possible. Third， we should plant more trees， because plants can turn CO2 into oxygen. More importantly， we should form the habit of saving energy in our daily life.

全球变暖-The Global Warming

The Global Warming

People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer daysg.

The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.

To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.
