What will happen if more of the Amazon forest is cut down? According to climatologists, two things are likely to happen: there will be serious effects on the world’s climate and the air that we breathe will lose some of its oxygen. Why is this? Trees absorb Carbon dioxide from the air and give out oxygen into the air. Some scientists believe that they provide 50% of the world’s annual production of oxygen.
If we lose the tropical forests, the air will contain much less oxygen and much more carbon dioxide: It will become difficult- perhaps even impossible- to breathe.
With more carbon dioxide in the air, the temperature will rise; the ice-cups at the north and south poles will melt; the sea level will rise and hundreds of seaside towns will be flooded.
Scientists do not all agree about the calculations which can be done in different results. But all of them agree that if they destroy the Amazon forest, it will be an environmental suicide-like losing an ocean. Life on earth will become difficult, and it may become impossible.

Part Two: Written Expression(5 pts)
Deforestation is one of the major causes of pollution. Write a paragraph talking about their causes, consequences and solutions by using the following notes:
a) -Causes (burning forest/ industry uses)
b) -Consequences (more CO2 less oxygen/ temperature increases/ poles melt/seaside towns flooded)
c) -Solutions (plant more trees/ protect forests from fire, destruction, and rubbish/make people aware of the problem).
