【答案】Dear fellow students，
Recently， some students are usually seen wasting food. I am writing to call on everyone to participate in the activity of saving food.
Saving food is of vital significance. It is not easy for farmers to produce our food， and we should cherish every grain of it. Besides， the COVID-19 is still here and we shouldn't be too optimistic about our food supply. And this is what we can do： When eating at the school， buy no more than you can have. When eating out， take your leftovers back home.
I am convinced that， with our joint efforts， the phenomenon of wasting food will disappear.
