From the chart above, we can see that the cost of food, paper, water and electricity increased by 10%, 8% and 15% in 2009. As high school students, what should we do to build a “low-carbon school” in the future? I think we must do as follows:
Firstly, we should form the habit of saving water and electricity. Never leave water running unnecessarily while brushing our teeth and washing hands. Meanwhile, whenever we leave classrooms or our dormitories, make sure that the lights are turned off. Secondly, we should also save every piece of paper as well as other materials by writing on both sides of the paper or using materials to be recycled. Thirdly, in order to reduce food waste, we should get our meals according to how much we can have. Besides, we should often offer to remind our schoolmates to save energy.
If we all do like this, I am sure our school will become more and more beautiful.
