We are lucky to live in a rich country where we have many things. However, most of us usually  31   some things.

Electricity is one thing  32  we waste most. Lights, TVs,  33  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   34  less than a second to do it. Anyhow, not wasting electricity save money, because we do not have to  35  the electricity we do not use.

The second thing that we often waste is water. Fresh water is precious*,  36  it shouldn¨t be wasted.It is only a simple matter of turning off a tap*. I am sure  37  can do this easily if he wants to.

 38  big waste is food. My mother  39  cook so much food that much of it was thrown away. I told her we had wasted so much  40  . She thought I was right and now cooks  __41_  what we can eat.

   It is not  42   to be wasteful. I find there is a simple  43  of not wasting things. That is to use only what we  44  . Do not touch what we do not need.  45   this way we can stop being wasteful.
