Greenhouse effect

To protect the trees from the cold air a special kind of house is built in cold countries.

It is called greenhouse. This house generally made of glass. For this reason the sunlight enters the room.The becomes hot by the sun ray but the hot air in the house can not pass out. In our air space carbondioxide acts like a greenhouse.The increase in global warming is caused by the increased amount of carbondioxide around the earth. The green house effect is the cause of that global warming. This could destory wildlife and wilderness, raise sea levels and there by flood coastal areas and farmlands.As a result of the rise in sea level the southern part of the country may one day go under water. Deforestation is mainly responsible for this problem. So to avoid this problem, we must have to plant more trees.
