उत्तर
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.
