Pollution and Physics


What is the link between pollution and physics?
I have to write a paper in physics and have decided to write it on plastic pollution, but I do not know how exactly plastic pollution and physics are related.
How are they related?


I am not too sure how plastics pollution can be related to physics. The non-degradable nature of most plastics is really much more in the realm of Chemistry than Physics.

However the pollution of the world, espeicially the oceans by the 'disposal' of plastics is a world wide problem. We use far to much plastic in packaging, especially of our food, and this is usually not bio-degradable and is a major hazed to marine life.

If I was you I would concentrate on the nuclear industry (regretfully they have had plenty of bad publicity over the years) since this is one area where Physics is directly related to pollution.

The waste products from fission reactors in the nuclear industry could be a major source of pollution unless well controlled. In addition to the problems of the disposal of waste from commercial power stations there have also been a few major accidents such as Three Mile Island, Chernobyl, Windscale and Chelyabinsk.

Other ideas are:
Light pollution (affecting our lives at night and of particular nuisance to astronomers) Potentially dangerous devices such as lasers and high voltage power supplies.
You might also like to consider the possible damage to the human brain from electromagnetic fields produced by the radiation from power lines and mobile phones.
The emissions from defective microwave ovens might also be an area worth looking at.
How about noise pollution in cities and the work place a real problem in modern day life and a factor leading to stress.
