More than half of the students, 60%, are completely agree with this act, as it is not only beneficial to recycling of resources, but also can help students develop their habits of garbage classification. However, surprisingly, 30% of the students hold the opposite opinion. They consider it troublesome and resist changing their habits. Besides, the rest care little about it, for they think it is none of their business.Personally speaking, I’m in favour of this act. I believe it’s crucial to raise people’s awareness of garbage classification, from which we will get great benefits for the future.Yours，　Li Hua
