One possible version
As is known to all , waste has become a more and more serious problem.
We can easily see many people do not turn off the lights or the electric fans immediately after they use them; many disposable products are being used in our daily life; many students drop a lot of good food into the garbage can. In the office, some equipment is often on for a long time but nobody is using it. What’s worse, a great deal of paper has been wasted .
In my opinion , we should call on more and more people to fight against waste. Only through these measures can we reduce waste .
