SOS save our space

Everybody should be concerned with saving our space. We live in cities and towns and we should do our best to keep them clean. First of all we shouldn't throw the rubbish in the street, on the grass and ect. We should throw it into the rubbish-bin. If we see something thrown on the ground we should pick it up and throw it into the rubbish-bin. If everybody dose so our city will be clean and we can walk in a cleaner city with pleasure. Besides, i think that the rubbish shouldn't be burned but it should be worked out and reproduced. It will also develop the economy of the country. If more people start riding bicycle fever cars will be used and our air will be less polluted. But it is unbelievable because people like comfortable means of transport. And that's why they prefer to drive cars.
