Factually waste
separation is vital to create an environment-friendly campus. Firstly, waste

其实垃圾分类对创造环保型的校园来说至关重要。首先，垃圾分类对保护环境贡献很大。由于一些垃圾是可循环利用的，而另外一些是不可循环利用的，如果所有学生都能自主地把可循环利用的垃圾和不可循环利用的垃圾区别开来，对环境造成污染的风险会大大降低。其次，垃圾分类能使人们在处理垃圾过程中节省大量的时间和精力。

With
the rapid increase in the amount of rubbish at the campus, rubbish
classmification does not permit of any delay. On the one hand, as the
well-educated people, college students should act as hosts of the universities
and separate waste from this moment in their daily life. On the other hand,
university authorities should strengthen students' awareness of environmental
protection and guide students to separate waste in a reasonable way.(166
