Put an end to food waste
Today I shall give a short speech on food waste.
A recent survey showed that in our country, millions of tons of food is thrown away every day. And in our school, we can see some students throwing away food too.
Think of a grain of rice wasted from your plate. How much effort might have been made to grow it, harvest it, cook it and put it on your plate? Yes, dear friends, even a single grain of food is too precious to waste. Besides, think of those who are suffering from hunger. Every year, there are about 3 million children in the world who starve to death.
Take what you want but eat what you take. Don't waste food!
Thank you.
