Next, the released CO2 causes a climate change. CO2 is the one of the element exists in the air a lot and reacts with the chmical properties to change climate.

At last, the percentage of CO2 increased much more than before. Because the development of industry, we use more cars and industrial products producing CO2.

In brief, to reduce of releasing CO2, we can use the solar energy, hybrid energy, and the natural gas instead of gasoline.
