The Earth has warmed by about half a degree（0.50℃）over the last 100 years. It could be getting warmer on its own, but many scientists think that people are making the Earth warmer by making a greenhouse effect. The greenhouse effect is important.  Without it, the Earth would not be warm enough for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals.

Many of the things we do every day can change the Earth’s temperature by sending greenhouse gases into the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases.

     Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water.

The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals.

     Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don’t do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world.

If you put a buzzard(秃鹰) in a cage without a roof(顶棚), the bird will be a prisoner. Even though it can fly, it can’t fly through the open roof. The reason is that a buzzard always begins a flight from the ground with a run of 3 or 4 meters. Without space to run, he will not even try to fly, but will stay in his small jail(监牢) for the rest of his life.
The ordinary bat that flies around at night cannot take off from the ground. If it is placed on the ground, all it can do is shuffle(穿梭) about helplessly. If it reaches a higher place, it will be able to throw itself into the air. Then it takes off quickly. But on flat ground, it will never fly.
A bee dropped into a cup will be there until it dies, unless it is taken out. It never sees the means of escape at the top, but keeps trying to find some way out through the sides near the bottom. It will look for away where none exists, until it completely destroys itself.
In many ways, there are lots of people like the buzzard, the bat and the bee. They are struggling with all their problems and frustrations(挫折)，not realizing that the answer is right there above them.
