AIR POLLUTION
When fossil fuels are burnt in power stations, factories, cars, planes and our homes they give out smoke. This smoke contains gases which are harmful to the environment. This is called air pollution.
In very busy cities where there are a lot of people, cars and factories making smoke, there is often a brownish haze in the air called smog. Smog is a mixture of smoke and fog. As well as not looking very nice, smog can damage our lungs if we breathe it in.
In December 1952, London was engulfed by a terrible smog, which lasted for five days. Road, rail and air transport were brought to a standstill. Worst of all, the smog, said to be like pea soup, caused the death of around 12,000 people and illness to many others.
The heavy smog in London reminds us that we still need to cut down on the levels of air pollution in our world.
