Atmospheric Pollution

BACK

Like light pollution, atmospheric pollution is a side effect of the industrial revolution of our civilization. Whilst some atmospheric pollution can have natural sources, for example volcanic eruptions, the majority comes from the combustion of fuels for transport, power, waste incineration and other industrial activities.
Since the beginning of the industrial revolution we have increased the amount of pollution in the atmosphere. Whilst still being composed of mainly oxygen and nitrogen, the levels of trace gasses, many of which are harmful to both humans and the environment, are increasing. These gases can result in poor air quality, causing breathing problems and is linked to an increase in the likelihood of cancer. It can also produce acid rain which corrodes buildings, damages vegetation and makes streams/rivers unsuitable for plant and animal life.

Another effect of atmospheric pollution is that some of the trace gases are becoming stuck in the atmosphere and leading to a reduction in Earth’s ozone layer. This together with the build up of greenhouse gases is resulting in a rise in the global temperature leading to global warming.
This affects our climate, the air quality, water quality and the ability to sustain life on our planet. To slow down global warming many countries have taken action to cut to start to reduce emissions from combustible fuels.
