The common I found in school is the nature gas which was in the canteen. It is the major form of energy that we use everyday. At most of time, people use nature gas as fuel when they were cooking and also in the hybrid vehicle. It is much cleaner than the oil and coal, but it still produce lots of carbon dioxide while it burning. Therefore, we need to save it, and use it sparingly.
This photo was taken in the dining room where is located in the kitchen. It was mostly used in the cooking by human beings. In my life, the stove in my home is just burned by nature gas because it was cheap and easy to keep. However, this is one kind of non-renewable resources which belongs a type of fossil fuel. It was lied on the deep underground just similar with oil. Therefore, we need to protect it. In my opinion, I think that to reduce eating meat diets is one of the good way to protect this kind of commons because cooking meat is always need more energy than the vegetables. Moreover, for myself, I would like to to some of my life-style to save this natural resource which is natural gas. For example, I would like to have less meat diets so that it would cost less energy. Furthermore, I am willing to have more boiled food than fired food because it also use less heat to make food cooked. The reason why I do this is because the carbon dioxide from natural gas are causing the global warming, and to protect the environment is just protecting ourselves.
