Can we save the earth?

Of course we can! But every action you do, affects the earth. Learn how to save the earth before taking actions. If not you will be...(example)burning down some part of the forest for growing crops while thinking "I can save the earth!".How to save the earth? You can save ELECTRICITY, burn less fuels(example:wood,oil,etc.), etc. One action can affect the whole earth! Example: burning down some part of the forest. Burning requires OXYGEN that WE NEED and produce CARBON DIOXIDE which we can also produce through repiration. Too much carbon dioxide in the air is not good at all.
This is because, the carbon dioxide will rise to the air as it is produced, then traps heat. Heat comes into the earth and goes out of the earth. When heat reaches the earth, the carbon dioxide will trap some of the heat while it goes out of the earth. As there is MORE carbon dioxide to trap HEAT, LESSER heat will travel back into the space. Thus, more heat will be trapped in EARTH and the temperature of the earth will INCREASE as there is MORE heat.

Ya we can save the earth.
However, it takes more effort than easily said.
Everybody must put in the effort and full commitment.
Hope to see more greenery for our future generation.
If not the mother earth will collapse as predicted to be Dec 2010. (Doom's day).
