We aren't conscious that men damage the Earth, our planet every day. There are many causes:

a) For example, rainforests are being destroyed, because too many trees are being cut down.
b) The building of roads and motorways is changing the landscape.
c) Industrial waste is polluting our rivers and our seas.
d) The factory smokes and the fumes of our cars, are polluting the air that we breathe.
e) The CFCs of aerosols, refrigerator and air conditionings are destroyed the ozone layer.

I wonder: Men have travelled to the moon, will they be able to save the earth... I think so.

However, I think everybody is obliged to do something to look after the environment. We can start at home, we must put the glass in the bottle-container, the batteries in the battery-containers, the paper in the paper-container.

You can go to school on foot, you have to put the rubbish into the rubbish bin.
