List any two steps you would suggest to minimise environmental pollution caused by burning of fossil fuels.

We could minimize the environmental pollution caused by burning of fossil fuels by:

(a) Fitting catalytic convertors in the vehicles. The catalytic convertor is a device which changes the harmful gases coming from the engine of car to harmless gasses before releasing them in the air

(b) Installing electrostatic precipitators in the chimneys of thermal power plants and factories. By using this we can control the pollution caused by the burning of fossil fuel.

The unburnt carbon particles and fly ash particles present in the smoke keep on depositing on the walls of chimney and don’t go to the air.
