We are lucky to have many things. However, most of us usually waste them.

Electricity is one thing that we 21 most. Lights, TVs, 22 and other things are often kept on even when on one is using them. We should turn them off when we do not need them. It 23 less than a second to do it. Anyhow, not wasting electricity can save money because we do not have to 24 the electricity we do not use.

The second thing that we often waste is water. Fresh water is valuable, 25 it shouldn’t be wasted. It is only a simple matter of turning off a tap. I am sure that 26 can do this easily if he wants to.

Other big waste is food. My mother 27 cook too much food and much of it was thrown away. I told her we had wasted so much 28 .She thought I was right and now cooks only what we can eat.

It is not right to be wasteful. I find there is a simple 29 of not wasting things. That is to use only what we 30 Do not touch what we do not need. In this way we can stop being wasteful.
