Question : How are industries responsible for environmental degradation in India? Explain with examples.
Answer : Although industrialization has contributed significantly to India’s economic growth and development the increase in pollution has resulted in gross degradation of our environment. Different industries are responsible for the pollution of (a) Air (b) Water (c) Land (d) Noise.
• Air pollution is caused by the presence of high proportion of undesirable gases, such as sulphur dioxide and carbon monoxide in air.
• Airborne particulate materials contain both solid and liquid particles like dust, sprays mist and smoke. Smoke is emitted by burning of fossil fuels in different industries such as brick kilns, refineries and smelting plants etc.
• Many times pollution norms are not followed by the industries. The effluents are not treated before their discharge into air or water bodies.
• Toxic gas leaks can be very hazardous with long-term effects; as happened after the Bhopal Gas tragedy. Hence meticulous maintenance of equipment is necessary.
• Water pollution is caused by organic and inorganic industrial wastes and effluents discharged into rivers and lakes. The main culprits in this regard are paper, pulp, chemical, textile and dyeing, petroleum refineries, tanneries and electroplating industries.
• They release toxic dyes, detergents, acids, salts and heavy metals like lead and mercury, various pesticides, fertilizers, synthetic chemicals, plastics and rubber etc., into the water bodies.
• Fly ash, phospho- gypsum and iron and steel slags are the major solid wastes in India.
• Thermal pollution of water occurs when hot water from factories and thermal plants is drained into rivers and ponds before cooling; this greatly harms the aquatic plants and animals.
• Mismanagement of wastes from nuclear power plants can cause cancers and birth defects.
• Soil and water pollution are closely related. Dumping of wastes such as glass, harmful chemicals, industrial effluents, packaging materials, salts and garbage renders the soil useless. Rain water percolates through the soil carrying the pollutants to the ground and the ground water also gets contaminated.
• Noise pollution not only results in irritation and anger. Unwanted sound is an irritant and a cause of stress. Industrial and construction activities machinery, factory equipment, generators, saws and pneumatic and electric drills also make a lot of noise. Health problems caused by sound pollution include : hearing impairment, increased heart rate and blood pressure and other physiological effects.

Question : Have you read about the Kalinganagar controversy? Collect information from different sources and discuss.
Answer : Kalinganagar is another instance of the resistance of the tribal to losing their lands to industrialisation. The Tata Group formed a nexus with the Government of Odisha to set up a giant steel plant in Kalinganagar area. The tribal people revolted in the region because they knew that both their life and livelihood would be at stake. On 2nd January, 2006 in a police firing incident, 13 tribal people were killed. Subsequently, when their bodies were being handed over to their relatives, it was found that palms of five tribal people had been chopped off (for identifying them by fingerprinting) by the doctors conducting the postmortems on them. The above controversy has affected the establishment of this steel plant and also the industrialisation in Odisha, overall.

Question : How do industries create air, water, noise, and thermal pollution ?
Answer : (i) Air Pollution : It is caused by the presence of high proportion of undesirable gases such as sulphur dioxide and carbon monoxide. Smoke is emitted by chemical and paper factories, brick kilns, refineries and smelting plants and burning of fossil fuels in big and small factories that ignore pollution norms. Toxic gas leaks can be very hazardous with long term effects. It adversely affects human health, animals, plants, buildings and the atmosphere as a whole.
(ii) Water Pollution : It is caused by organic and inorganic industrial wastes and affluent discharged into rivers. The main culprits in this regard are paper, pulp, chemical, textile and dyeing, petroleum refineries, tanneries and electroplating industries that let out many harmful substances into the water bodies.
(iii) Noise Pollution : It not only results in irritation and anger, but also causes hearing impairment, increased heart rate and blood pressure among other psychological effects. Industries, factories, generators, electric drills, etc. make a lot of noise.
(iv) Thermal Pollution : It occurs when hot water from factories and thermal plants is drained into rivers and ponds before cooling which affects the aquatic life. Wastes from nuclear power plants, nuclear and weapon production facilities cause cancers, birth defects and miscarriages.
