Question 8

Write two examples of highly-polluting industries. What preventive measures can be taken to control industrial pollution?

Answer

Two examples of highly-polluting industries are cement industry and Iron-steel industry.

Following are the preventive measures that can be taken to control industrial pollution:

  1. The industrial wastes should be properly treated in waste treatment plants before they are discharged.
  2. More trees should be planted as trees reduce dust, smoke and other pollutants from the air.
  3. The government should take strict actions against those industries which discharge higher amount of pollutants into the environment than the level prescribed by the central or state Pollution Control Boards.

Types of Industries

Industries are classified by sector: Primary (extracting natural resources — farming, mining, fishing), Secondary (manufacturing — converting raw materials into products), and Tertiary (services — transport, banking, IT, tourism). They are also classified as large-scale vs small-scale, and heavy (bulky raw materials) vs light (small raw materials).

Factors of Industrial Localisation

Eight factors determine where industries are located: raw materials (heavy industries near sources), power/energy, labour (skilled or unskilled), transport (roads, railways, ports), market (near consumers), capital (investment), water supply, and government policy (tax incentives, SEZs). A steel plant locates near iron ore and coal, while a bakery locates near its customers in a city.

Major Industries of India

Key Indian industries include: Iron and Steel (Jamshedpur, Bhilai, Durgapur, Rourkela, Bokaro), Cotton Textiles (Mumbai "Cottonopolis," Ahmedabad "Manchester of India"), IT (Bengaluru "Silicon Valley of India," Hyderabad, Pune), Sugar (UP, Maharashtra), and Jute (West Bengal). World industrial regions include the Ruhr Valley (Germany), Silicon Valley (USA), and Keihin (Japan).
