The Problem Of Polythene Pollution
Polythene pollution is everywhere, and the problem is getting worse. For most of us, the problem is seen as one of visual pollution, where plastic bags litter streets, roadways, and in some cases scenic areas across the country. No one will argue that polythene is useful. The plastic bags we use to carry home food or products are for the most part very light and very strong. Using these bags is not really the problem.

This by the way isn't true in all countries. In some places on this earth, trees to produce pulp are scare. The real value in using paper instead of plastic however is that the former is biodegradable, while polythene is not, unless you want to wait around a few thousand years. Small Steps - There are small steps being taken. We still use a vast number of plastic bags, and in spite of anti-littering campaigns, and our best intentions, too many of them find their way into places they really don't belong. Many retailers are encouraging shoppers to bring their own bags, usually canvas bags, which will last many years and don't tend to be discarded. Some stores even sell these bags, usually showing...
