The term "plastics" covers a range of synthetic or semi-synthetic organic condensation or polymerization products that can be molded or extruded into objects or films or fibers. They consist of long chains of polymers. Their name is derived from the fact that in their semi-liquid state they are malleable, or have the property of plasticity. Plastics vary immensely in heat tolerance, hardness, and resiliency. Combined with this adaptability, the general uniformity of composition and lightness of plastics ensures their use in almost all industrial applications today
Today plastics have replaced metals, natural fibres and hides, paper wood and stone and glass ceramics. Manufacturers use these plastics to make their products stronger, lighter, inexpensive and durable. Plastics' versatility is responsible for its many uses: everything from car parts to doll parts, from soft drink bottles to the refrigerators they get stored in. From the car you drive to work in to the television you watch when you get home, plastics help make your life easier and better.
Plastic bottles mean we can actually lift an economy-size bottle of juice. And should we accidentally drop that bottle, it is shatter-resistant. Plastics also help to conserve energy in our homes. Vinyl siding and windows help cut energy consumption and lower our heating and cooling bills. Plastics have also replaced paper in packaging, wood and stone in making furniture etc. Plastics thus have become an integral and indispensable part of our lives.
But, as useful they are, plastics do have disadvantages. The biggest problem is that most plastics take a very long time to decompose. Deciding how to dispose the plastic wastes has become a major environmental concern. As more and more plastic packaging materials are used by consumers, more plastic waste is generated. Since most plastics do not easily breakdown, this problem contributes significantly to environmental pollution. Plastics use up natural resources, consume energy to
manufacture, create litter, choke marine life and add to landfill waste.
There is a growing international movement to ban or discourage the use of
plastic because of their environmental effects. Countries from Ireland
to Australia are cracking down on the bags and action is stirring
in the United States. Ooty too has banned the bags.
The bottom line of this is that we cannot eliminate the monster of plastic which we ourselves have created. But we can definitely control and limit the use of plastic.
