We are lucky to live in a rich country where we have many things. However，most of us usually waste some things.
Electricity is one thing that we waste most. Lights，TVs，radios and other things are often kept on even when no one is using them. We should turn them off when we do not need them. It takes less than a second to do it. Not wasting electricity also saves money，because we do not have to pay for the electricity we do not use.
The second thing that we often waste is water. Fresh water is precious （宝贵的），so it shouldn't be wasted. It is only a simple matter of turning off a tap. I am sure everybody can do this easily if he wants to.
Another waste is food. My parents used to cook so much food that some of it was thrown away. I told them we had wasted some food. They thought I was right and now cook only what we can eat.
It is not right to be wasteful. I find there is a simple way of not wasting things. That is to use only what we need. In this way we can stop being wasteful.
