In one well-known city, for (1) example, poisonous gases from cars (3) pollute the air so much that traffic policemen have to wear oxygen masks. We have cut down so many trees that there are now vast (4) areas of waste land around the world.

Many people who work in London prefer to live outside it, and to go to their offices, factories or schools every day (5) by train, car or bus, even though this means they have to (6) get up earlier in the morning and come home later in the evening.
One advantage of living outside London is (7) that houses are cheaper. Even a small flat in London without a garden costs quiet a lot to rent. With the same money, one can get a little house in the country with a garden of one's (8) own.
