“The use of CNG and LPG as fuels for automobiles helps us to minimize air pollution and maintains ecological balance”. Do you agree with this statement? If yes, explain.

Yes, the fact is very true. As we have seen in this chapter, CNG and LPG release harmful materials like carbon di oxide, carbon mono oxide, Sulphur and nitrogen oxides in lesser amounts than petrol and diesel or oils. They give almost same energy comparing to petrol causing less pollution. But fact remains that it also leads to some pollution whether less or more and also it is exhaustible. So such fuels are better than that of petrol and diesel for automobiles but are not something perfect to be used for maintaining ecological balance.
