Air pollution in cities is growing at an alarming rate. What measures could be taken to address this problem?

Air

pollution

can be defined as the addition of something harmful to the air at a faster rate than it can be absorbed. Everyone should be concerned about air

pollution

. It affects us all, and as it continues to worsen, so the environmental impact increases. One of the major causes of air

pollution

in cities is car

use

. Cars are used for even the shortest of journeys, and all efforts by governments to encourage people to

use

public transport seem to be failing.

Industry

Suggestion

The industry

is another major cause of

pollution

in our cities, but fortunately, new industrial sites are being built away from large urban centres. It is said that there are too many contributing factors for us to decide exactly which one is the main problem, but I believe that one of the most serious problems that needs tackling is the

use

of the car. In some cities laws have been passed concerning car

use

. Athens,

for example

, only allows a certain number of cars into the city centre each day. In my opinion,

this

is a good idea. With

this

kind of law people have no choice and are forced to

use

buses and trains.

This

ensures governments know that public transport will be used, and can

therefore

justify the investment and expense of ensuring the system works properly. Another thing governments could do is to force people to have their cars checked for carbon emissions and fine people with cars that produce high levels of harmful gases.
