Speech

I must write the manuscript of speech in public speaking class. Tomorrow' class will do speech everyone. I am very strain whether I can make speech well or not. I will talk about environment problem.
My manuscript is this. Thank you very much for coming here to listen to my speech. I would like to tell you about environmental problems. These days, the earth’s climate is wrong.
In that, global warming is serious problem now. It is a phenomenon that average temperature of earth or ocean is rising a long time. In recent years, it was noticed the cause of global warming.
The main cause of global warming is deforestation. On the earth, the quarter of land is forest. Forest absorb carbon dioxide, and emit oxygen, and save water and give nutrition to land. But it is said that the land will disappear after a hundred year.
What do you think forest have any role for earth and al living things? It has important role more than we think. To make oxygen, it must save water which has high nutrition, raising ground, making foods and so on. It has relation to all things of our life.
Also it causes to raise the surface of the seas. In ARASUKA, glacier melts and became a lake. Also ice’s thickness becomes thin in the South Pole. All of ices melt in the South. The surface of the sea is rising about 70 meters. Also Greenland’s glacier decreases remarkably these forty years. About hundred later, it is said that the surface of the seas will rise, average fifty centimeter, max one meter.
First, we reduce the consumption of electricity. Stasis shows that electricity is most used other energy in our home. In that, air conditioner is quarter of all electricity. So we should use fan instead of air conditioner.
Second, we save water. It is not good waste of water. We must save water when we take a bath, wash glasses or plates, and so on.
Third, we grow plants. If plants increase, it is good.
