Answers
Answer:
1. Development of industries helps the country to accumulate higher volume of wealth for the welfare of the nations as the per capita output in industry is much more higher than that of agriculture.
2. The iron and steel industry is basic to the industrial development of any country because iron and steel forms the basis of infrastructure for industrial development. Steel is used as basic material in the manufacture of metal products, electrical machinery, transport equipment etc.
3. Iron ore is the raw material used to make pig iron, Around 98% of iron ore is used in steel-making. During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).
4. Industries cause environmental degradation through air pollution, water pollution, land pollution and noise pollution. Inappropriate disposal of waste products and pollutants from industries harms the natural environment. Industrial waste may be toxic, ignitable and corrosive.
5. Control Of Environmental Degradation
Minimising the use of water for processing by reusing and recycling it in two or more successive stages.
Harvesting of rainwater to meet water requirement.
Overdrawing of ground water reserves needs to be regulated legally.
Smoke can be reduced by using oil or gas instead of coal in factories.
