Three ways through which industrial pollution can be reduced are:
(i) Machinery and equipment can be used, and generators should be fitted with silencers to reduce noise pollution.
(ii) Waste and effluents should be recycled or treated through biological processes and mechanical means to reduce water and air pollution.
(iii) By fitting suitable smoke screens in factories with electrostatic precipitators, scrubbers, etc., air pollution can be minimized.

Q3: Describe the role of industries in the development of agriculture. (2019)

(i) Industries provide agricultural implements, machinery, and other products to the agricultural sector such as PVC pipes, irrigation pumps, fertilizers, pesticides, insecticides, etc.
(ii) Due to these products provided by the industries to the agricultural sector, agricultural production increases. These inputs also improve the efficiency of production.
(iii) The Green Revolution in Punjab and Uttar Pradesh was achieved only because industries provided products like fertilizers, tractors, and irrigation pumps to the farmers.
(iv) Thus, agricultural development is possible only due to the support from the manufacturing industries.
(v) Because of the inputs from the industry, employment opportunities in the agricultural sector also increase.

Q4: "Manufacturing sector is considered as the backbone of economic development of a country.” Support the statement with examples. (2021 C, Foreign 2017)
(i) The manufacturing sector provides the basic inputs to the agricultural sector. For example, industries providing tractors, harvesting machines, fertilizers, etc., that make the basic inputs for the sector. It helps in the modernization of the agricultural activity.
(ii) An example is the establishment of industries in tribal and backward areas. The industrial sector provides employment to a large number of people and improves their economic status.
(iii) The manufacturing sector improves employment because manufacturing sector adds value to goods. The country can export products instead of raw materials. For example, the USA.

Q5: Explain with examples the interdependence of agriculture and industries. (Delhi 2017)
Ans: The interdependence of agriculture and industries is based on many factors, such as adequate rainfall and good crops. Some examples are:
(i) When the rain fails and the crops fail, the industries suffer, and there are losses in businesses as the purchasing power falls.
(ii) If the cotton crops fail, the clothing industries suffer, and other industries also suffer.
(iii) If poultry farms do not produce enough eggs, the bakery industries that use eggs as their important ingredient also suffer.
(iv) Thus, the success and growth of agriculture are closely linked to the success and growth of industries.

Q6: Classify industries on the basis of the source of raw materials. How are they different from each other? (2016)
Ans: On the basis of the sources of raw materials, industries are classified as:
(i) Agro-based Industries: These industries draw their raw materials from agricultural products. For example, textiles, sugar, coffee, tea, and edible oil.
(ii) Mineral-based Industries: These industries draw their raw materials from minerals. For example, iron and steel industries, cement, petrochemicals, etc.
While in agro-based industries, value addition is done at every stage; in the case of mineral-based industries, refining is a more important activity.

Q7: "The textile industry is the only industry in the country which is self-reliant and complete in the value chain.” Justify the statement. (Delhi 2016)
Ans: The textile industry is considered self-reliant because products produced at each stage are used as raw materials for the next stage of production. The value chain refers to a number of activities that the industry performs right from the production of raw materials to the delivery of finished products. The textile industry completes this value chain within the country itself, without relying on imports or outsourcing. This self-reliance helps the industry maintain control over quality, costs, and timelines.

Q8: Classify industries on the basis of their main role. How are they different from each other? (Foreign 2016)
Ans: Industries can be classified according to the role they play in the economy of the country. They are:
(i) Basic or Key Industries: These industries supply their products or raw materials to manufacture other goods. For example, iron and steel and copper smelting, aluminum smelting. These industries help in the establishment of other industries.
(ii) Consumer Industries: These industries produce goods for direct use by consumers. Examples include sugar, toothpaste, paper, sewing machines, electric fans, etc.
The main difference between these two types of industries lies in their target market and the purpose of their production.

2. Transportation Network: The region has a well-developed network of roads and railways, facilitating the easy movement of raw materials and finished goods to and from iron and steel plants.
3. Access to Waterways: The presence of rivers like the Damodar and Subarnarekha provides a cheap means of inland water transport for iron and steel goods.
4. Market Proximity: The Chota Nagpur region is close to the city of Kolkata, which provides a large market for iron and steel products. Additionally, the region has access to banking, insurance, and financial services necessary for the functioning of iron and steel plants.
5. Availability of Cheap Labor: The region has a significant population that provides a pool of cheap labor from Bihar, West Bengal, Jharkhand, and Chhattisgarh. This availability of labor contributes to the concentration of iron and steel industries in the area.

Q3: How are industries responsible for environmental degradation in India? Explain with examples. (Delhi 2019)
Ans: Industries contribute to environmental degradation in India through various ways:
1. Air Pollution: Industries emit harmful pollutants such as particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds, which contribute to air pollution. For example, thermal power plants and factories release smoke and pollutants into the air.
2. Water Pollution: Industrial waste and effluents containing toxic chemicals, heavy metals, and organic pollutants are often discharged into water bodies without proper treatment. This pollutes rivers, lakes, and groundwater, affecting aquatic ecosystems and water quality. For instance, textile dyeing and chemical industries release untreated wastewater into water bodies.
3. Soil Contamination: Improper disposal of industrial waste and the use of chemical fertilizers and pesticides can contaminate the soil, affecting agricultural productivity and soil health. For example, heavy metals from industrial activities can accumulate in the soil, rendering it unsuitable for cultivation.
4. Deforestation and Habitat Loss: Industries often require large areas of land, leading to deforestation and loss of natural habitats. Forests are cleared to make way for industries such as mining, manufacturing, and construction. This results in the loss of biodiversity and disruption of ecosystems.
5. Climate Change: Industries contribute to greenhouse gas emissions through the burning of fossil fuels, industrial processes, and deforestation. These activities contribute to global climate change, leading to adverse impacts such as rising temperatures, changing rainfall patterns, and sea-level rise.
