     No air means death. Although we can't see it, there is air around us. So air is everything and it gives life

to every living thing. Bad air makes people ill. We must have fresh air to keep us in good health.

     In the city there are a great many people and there are too many cars running on the roads. The gas which

the cars spread out is full of poison. Every day we breathe it in again and again. This makes us feel sick.

     Besides so many cars, there are many factories too. From the chimneys of these factories, we get the

smoke usually in black and grey colour. This kind of smoke, when it mixes the air, is dangerous to our health.

It is because smoke contains many poisonous solids and gases. So in order to keep us healthy we have to go

out to the countryside to breathe more fresh air. Or we can go up hills to get more fresh air.
