How to protect our earth from Global Warming????????

I don't believe in Global Warming in the sense that it will end all life. The science is unproven.

As Im reading from some news the result almost come from using gas in your car or bike. that make the house glass effect working more faster. we can not stop it at least we can reduce it by try to using energy source alternative like what honda doing. car with water energy, I think that was the best way to reduce the global warming also dont forget to make reboisasi(grown a forest). It also can reduce the global warming effect.

I don't know if I even really believe it is global warming. Several hundred years ago the polar ice caps began to melt, the earth became warmer, and other things were going on similar to what is happening today. They didn't have cars then, nor many of the other things we have. It may be a cycle that the earth goes through. And with temperatures in my area dropping below 0 (farenheit) I have a difficult time believing in global warming.

God knows!!! its become a very big problem and our life styles wont change, so 1 day we will be eliminated from planet earth.... thats it....

Some say its because people are passing to much gas do you think this is true?
