Dear friend ，

   As we all know, one of today’s hot topics is to avoid wasting. As a matter of fact, it is a very challenging but meaningful task. As students, we may wonder what we should do.

    In my opinion, we should begin with our daily life. First of all, we had better not waste food. For example, in the canteen, we should eat up what we have bought instead of throwing away leftovers. What’s more, it is better not to waste the notebooks when they are half blank. Also, we can make full use of paper and pencils as well. Lastly, it is suggested that we should use our pocket money wisely rather than spend it on something unnecessary.

  In a word, we should take action immediately to advocate saving and avoid wasting.
