Global Warmng and ways to prevent them.

Nowadays, there are lots of carbondioxide being emitted all around the world by automobiles, factories, domestic buildings...etc. Thus, it causes global warming, resulting greenhouse effect. The Kyoto Protocal has been founded around 1990s, but the global warming is still happening fast. An Inconvenient Truth, the movie which Al Gore acts in, focuses on the world's most serious problem, global warming. However, as we can see in the title 'INCONVENIENT', people tend to think that this problem is not such a threat to the society.
I believe that this is the real problem and the cause of global warming. Yes, the discharge of exhaust gas and smoke is the problem. But the foundation of such problems are the wrongly set notions about the problem. Therefore, I am strongly convinced that compaigns or lectures or articles which can change the thinking of the people is the most necessary resolution.
Also, the government of the country should invest their budget as much as they can to the development of the green energy source. There are lots of eco-friendly energy sources that we can use besides fuels. Solar energy, which means creating energy from the sunlight, excretion energy, which means creating energy from the solid waste of the animals, wind power, tidal wave, water, electric, nuclear, and so on.
