Question

What are the various steps which can be taken to control (or reduce) pollution caused by burning fossil fuels?

Answer 1

Various steps can be taken to reduce the pollution caused by burning fossil fuels. These are as follows.
(a) The air pollution caused by the burning of petroleum fuels in vehicles can be reduced by using catalytic converters in vehicles. Catalytic converters convert harmful gases into harmless gases.
(b) The air pollution caused by the burning of coal in thermal power plants can be reduced by washing smoke and acidic gases with water in scrubbers.
(c) The air pollution caused by thermal power plants can also be reduced by installing electrostatic precipitators in their chimneys. The unburnt carbon particles and fly ash get deposited in the chimneys before the exhaust gases from the power plants are let into the air.
