The major problems of the environment are recognized as global climatic change, ozone depletion, water and air pollutions, deforesta­tion and resources degradation.23 billion tones of carbon dioxide is released in the air by burning fossil fuels causing Greenhouse effect. The Greenhouse gases are mainly contributed by the industrialized nations.By the middle of 21st century, earth’s temperature at present level of heat emission would go up by one to three degree Celsius and the sea level would rise between 30 to 100 centimeters.India has witnessed alarming environmental degradation in the last two decades. It is the sixth largest and the second fastest producer of Greenhouse gases.The key environmental pollutions related to indus­tries in India are water pollution, soil erosion, ground water contamina­tion and deforestation. Indian rivers are also suffering from high level of pollution due to enormous municipal wastes, industrial effluents and agricultural run-offs.According to expert findings, 70 per cent of India’s surface water is severely polluted. As per government statement in 1992, 3/4th of the total waste water generation is due to the municipal waste which is one half of the total pollution load.
