7. How do industries pollute the environment?
Industries are the reason there is an increase in the pollution of land, water, air and noise resulting in the degradation of the environment.
- Air pollution: Smoke is emitted by chemical and paper factories, brick kilns, refineries and smelting plants ,and burning of fossils fuels in big and small factories because of which undesirable gases, such as sulphur dioxide and carbon monoxide contaminated the air cause pollution.
- Water Pollution: Organic and inorganic industrial wastes and effluents are often discharged into rivers by industries like paper, pulp, chemical, textile and dyeing, petroleum refineries and electroplating. These kill the aquatic life and pollute the water and ecosystem.
- Noise Pollution: Industrial and construction activities create a lot of unwanted sound that can cause various physiological effects like hearing impairment, increased heart rate and blood pressure. Unwanted sounds are a source of stress.
8. Discuss the steps to minimize environmental degradation by industry.
Minimize the use of water for processing by reusing and recycling it.
- Treating hot water and effluents before releasing them into rivers and ponds.
- Treatment of industrial effluents can be done in three phases through mechanical, biological, chemical and physical process.
- Harvesting of rainwater to meet water requirements.
- Use of machinery, generators and equipment with silencers.
- Almost all machinery re-designs to increase energy efficiency and reduce noise.
9. The sugar industry is now shifting from north to south. Mention main reasons.
