Answer 2

ndustrialisation has led to increased pollution of air in following ways:

(i) Due to industrialisation, the consumption of fossil fuels has increased. Combustion of fossil fuels has increased production of gases like CO, SO2, SO3, NO2 and CO2 which are toxic.

(ii) There has been depletion in the ozone layer because of increase in the production of chemicals like chlorofluorocarbons which are used as insulators, refrigerants, solvents and aersol propellants. This has resulted in the entry of UV rays into Earth's atmosphere, which has affected various organisms.

(iii) Combustion of fossil fuels also increases the amount of suspended particles in air causing pollution.
