[-1:21.00]A Reading     page 92    Helping the Environment
[-1:22.00]These days we are all aware of the many threats to the environment
[-1:23.00]and the need to act in a responsible manner
[-1:24.00]to protect the world which we all share.
[-1:25.00]Many people say that they are in favour of the 'green' movement.
[-1:26.00]However,it is often difficult to find anything practicalwhich you can do to help.
[-1:27.00]If you live in a big city,
[-1:28.00]you may feel that you cannot take any action to support the cause.
[-1:29.00]But one thing you can do is to try to buy'green' products.
[-1:30.00]For example,let us consider the problem of the ozone layer.
[-1:31.00]Around the earth,there is a thin layer of ozone.
[-1:32.00]This gas protects us from many of the harmful rays of the sun.
[-1:33.00]A few years ago,scientists in the Antarctic first became aware of holes in the ozone layer.
[-1:34.00]If these holes continue to get bigger,
[-1:35.00]more and more harmful rays from the sun will reach us.
[-1:36.00]As a result,more people are likely to get skin cancer.
[-1:37.00]Further research into the problem showed that the ozone layer is being destroyed by gases called CFCs.
