I feel global warming everyday of my life. I couldn't see colorful leaves last autum. I read articles or books saying many species are going extinct. Likewise, global warming is a really serious matter of 21th century. The main cause of this is an increase in atmospheric greenhouse gases, especially CO2.

Green house gas emmision lead to global warming, and it results in climatic changes, a rise in sea levels, and changes in the distribution of disease-bearing organisms.

Then, what should we do to stop global warming?We should reduce green house gas emmision.
Firstly, we should develop eco-friendly sources of energy, like renewable and CO2-free energy.
Many countries are trying to develop alternative energy sources, like solar energy and Biomass fuel. To encourage developing these energy, the government needs to support companies which develope these kinds of energy or use these energy.
Also, the government should enlist global cooperation, like Kyoto Protocol, and UNFCCC. Because, global warming cannot be removed by only one country's trying.


Secondly, we should make personal efforts to cut emissions of CO2. There are many ways we can follow in our daily lives. For example, we should walk then using car. We should try to recycle cans or plastics. Also, we can plant trees so we can reduce cooling bills(?) in Summer.

To sum up, government should try to develope eco-friendly energy, and encourage people to live more environmentally friendly.
