Some people believe that air travel should be restricted because it causes serious

pollution and will use up the world's resources.?

The issue of the impact of air travel on the environment has heated up in recent years, following the concern that more and more people turn to it as a means of travel. Restrictions have been preferably imposed on air travel, according to some people. There are some points in their argument.

The first is that aircrafts have been responsible for a large proportion of air pollution. Planes, either filling or taxiing, contribute a large proportion of local emission annually. Some might suggest that air is the only suitable mode of transport for long distance trips. This viewpoint is fallacious. Trains, for instance, serve as an optimal alternative, consuming less energy and causing less pollution.

As well as air pollution, aircrafts can cause noise pollution. Although it is difficult to measure the actual impact of noise on people's everyday lives, its ability to increase the anxiety and levels of annoyance has been confirmed. Especially to those living in the neighbourhood of an airport and around the flight paths, noise created by aircrafts is indeed a headache.

Although travelling by air is likely to cause problems, it is not to say that air navel should be significantly restricted. Alternatively, air travel can be operated in a manner that its strengths can be fully taken advantage of. For example, by replacing old engines with cleaner ones, people can mitigate the environmental impact caused by flying. Meanwhile, aircrafts have a higher capacity, allowing greater numbers of passengers for each flight and thereby giving the best possible values to the fuel?used.

In the light of the facts outlined above, substantial thought should be given to the problem of pollution caused by aircrafts. However, it does not automatically mean that air travel should be curtailed. Instead, people should make adjustments and improvements wherever appropriate to ensure the optimal use of this form of travel.
