As we all know, the problem of wasting in our canteen is severe. For example, some students just throw away what they don't like eating. Some leave the water running after doing the dishes and leave the air--conditioner on after leaving the canteen. It is not only a waste of money, but also makes global warming even worse.
In my opinion, it is everybody's duty to fight against wasting. On the one hand, we should form the habit of eating what we order. On the other hand, we should make it a rule to save water and electricity when possible.
That's all. Thank you！
