Plastic mainly can be divided in two broader classifications namely. * Thermoplastics * Thermosetting plastics Both these varieties of plastics are not biodegradable that cannot be acted by micro organisms leading to the breakdown of the molecules. Generally most f the organic materials such as proteins in human and animal systems, paper, wood, vegetable materials etc. Re prone to bacterial action and get putrefied leading to normalization. But it is not possible for any plastic waste material to undergo degradation leading to normalization. The plastic packing and other waste material will be present in the environment for indefinite time. Hence the disposal of plastic waste material has created a very great challenge to the present generation. Sources The main sources of plastic pollutants are the polythene bags. Besides this the broken home appliances made of plastics, broken plastic chairs and furniture mainly contribute to the waste materials.

The industries producing plastic materials also release plastic waste materials into the land and water sources. There are several drawbacks of using polythene: * It creates unaesthetic appearance in public places, residential colonies, tourist spots, and others. * Because of its lightweight, they are very easily lifted by winds and may reach open drains, which further cause blocking of sewer lines, and floods during monsoon If dumped in landfills, they stay for a long time causing impaired biochemical reaction. The coloring pigment in colored polythene bags leach out to oil in dumpiest causing ground water contamination. * The intake of polythene bag by stray goats, cows etc causes choking in the throat and stomach which leads to death and * Accumulation of polythene bags near the seashore is very common in India. Many states in India such of Harlan, Whimsical Pradesh, Tamil Nadia and others have banned the use of polythene. The Dogmatically or Toot of Tamil Nadia a hilly area was declared as plastic free zone.

Although efforts are applied to produce biodegradable plastic or polythene’s by using corn-starch, till now it is not commercially successful. Hence, there is no other option than to use them carefully keeping in mind the three important abbreviations for R- Reduce, Reuse and Recycle. Apart from plastics and polythene’s, there are different materials like paper, metal can, tin products etc which are being used as packaging materials. Effects 1 . It has been suspected that some of the polymer chemicals are ergonomic. 2.

Plastic polymer molecules can get into the system through the food chain or directly and can cause sterility. 3. Fishes are the main scavengers of plastic trashes and the polymer chemicals get absorbed into the body offish. When human beings eat such polluted fishes, they can develop deformities, defects in uterus etc. 4. Polythene and other vinyl polymer plastics present in the land can stagnate the water and produce breeding grounds for mosque toes. 5. Besides affecting fishes, many marine animals such as sea lion, seal, sea turtle, sea bird etc. E greatly affected by the plastic pollution of the sea. Some of the specific polymer molecules such as poly chlorinate phenols (Pubs) cause severe damage to human s well as animal reproductive system. Many of the industrial effluents as well as waste plastic articles are dumped into the sea that causes marine plastic pollution. 6. The domestic animals consumes plastic trashes without knowing its contents and become victims to the plastic pollution. 7. Nowadays the domestic sewage are greatly polluted by plastic waste materials as well as hinted detergents.
