请结合以上材料，可适当发挥，以No Wasting Food为题，写一篇l20个单词左右的作文。
No Wasting Food Recently, a growing number of restaurants and customers in China have joined the "Clearing Your Plate" cam-paign against wasting food, which was firstly called for by Chairman Xi.It is quite meaningful for us to take an active part in this activity. Not to mention the hard work farmers paid, it is a waste of food as well as money if we order too much food. Meanwhile, the environment will also be polluted by
the wasted food. What's more, eating too much is bad for our health.
Taking all this into account, more actions should be taken to support the campaign. On the one hand, the restaurants should introduce more dishes in smaller portions for choosing. On the other hand, customers should eat up all the food in our dishes and plates, order less or smaller dishes, or even take the leftovers home and enjoy them later.
In a word, I do think it is our duty not to waste food.
