Introduction:
Plastic is one of the major toxic pollutants of our time. Being a non-biodegradable substance, composed of toxic chemicals, plastic pollutes earth, air and water. Plastic causes serious damage to environment both during its production and disposal. So the only way to reduce the hazards of plastic is to reduce the use of plastic and thereby force a reduction in its production. Plastic plays the villain right from the stage of its production. The major chemicals that go into the making of plastic are highly toxic and pose serious threat to living beings of all species on earth. Some of the constituents of plastic such as benzene and vinyl chloride are known to cause cancer, while many others are gases and liquid hydrocarbons that vitiate earth and air. Plastic resins themselves are flammable and have contributed considerably to several accidents worldwide. The noxious substances emitted during the production of plastic are synthetic chemicals like ethylene oxide and benzene. Besides hitting hard the eco-system, which is already fragile, these chemicals can cause an array of maladies ranging from birth defects to cancer, damage the nervous system and the immune system and also adversely affect the blood and the kidneys. And, many of these toxic substances are emitted during recycling of plastic, too. Recycling of plastic is associated with skin and respiratory problems, resulting from exposure to and inhalation of toxic fumes, especially hydrocarbons and residues released during the process. What is worse, the recycled plastic degrades in quality and necessitates the production of more new plastic to make the original product. Plastic wastes clog the drains and thus hit especially urban sewage systems. The plastic wastes being dumped into rivers, streams and seas contaminate the water, soil, marine life and also the very air we breathe. Choked drains provide excellent breeding grounds for disease-causing mosquitoes besides causing flooding during the monsoons.
