1.Preface

There are so many pollutions in the world, especially the air pollution. Our world is facing a serious problem. Today I'm going to talk about a serious worldwide issue, which is called“Greenhouse Effect.” The problem of Greenhouse Effect is a hot issue. With technology is advanced, there is a global warming.


2.What’s “Greenhouse Effect.”

How did the Greenhouse Effect get its name?
It got its name because in its process, certain gases at like greenhouse glass. They trap the sun's heat in the atmosphere and prevent a lot of it from radiating back to outer space.

The greenhouse effect is similar to the greenhouse becuse both of them trap heat.
The greenhouse effect makes the atmosphere trap radiation, making the earth warmer.
The greenhouse stops warm air rising and escaping from it.


3.Greenhouse Effect and Earth

The greenhouse effect causes huge trouble by raising the temperatre & sea leavels of earth. If the temperature rises 2 degrees centigrade, 15% to 40% of animals and plants will die; if it rises 4 degrees centigrade, then 3,000,000,000 people will lack of water in the world. Now some part of the North Pole's glacier has been dissolved, and the sea level has arisen. Several little islands were flooded forever by this reason. Maybe our island will be flooded one day. 

Don't you think that is a terrible thing?
Since 100 years ago, the temperature has risen 1.3 degrees centigrade in Taiwan. It roses so fast that we should improve our environment protections.


4. How can we protect the earth?

(1)Send the information to family, friends, and classmates. Share why this is so important. 

(2)The power of the pocketbook; buy green products and donate to environmental organizations. 

(3)We can go to work or to school by public transportations more often and reduce the garbage, especially plastic bags.
 
(4)We also can plant trees.

So there are many ways to save our environment and it's easy to do.
Everyone should do the best, and don't follow somebody else in bad side

這是我之前的報告,這個議題是我自己選的,我也認為這是個滿嚴重的問題
事實上,地球暖化的問題日趨嚴重
如果我們再不好好保護環境,很快的就會遭受大自然的反撲
科學家也預測,最快在50年內,海平面就上升,淹沒70%的地面
上通識課的老師也說過,到時候台灣會幾乎被完全淹沒
所以地球生態的保護真的是十分重要阿!!!
