Question

Which of the following will be effective in reducing air pollution?

• A. Use of solar energy
• B. Use of CNG
• C. Use of electric cars
• D. Burying of plastics instead of burning

Answer 1

Answer: (A), (B), (C)

The correct options are
A

Use of solar energy

B

Use of CNG

C

Use of electric cars

Air pollution can be reduced by the following methods:

(i) Use of electric cars - It runs on electricity and does not emit smoke, therefore creates no pollution.

(ii) Using solar energy - It is a non-polluting and non-depleting source of energy.

(iii) Use of CNG as a fuel - It is cleaner than petrol and diesel.

Burning of plastics cause air pollution but burying them will cause soil pollution. Hence, it is not an effective way to reduce air pollution. Plastics should be recycled.
