Q1 of 18 Page 100

You are expected to leave behind a good environment for your future generation. In that case, which one of the following fuels, will you use nowfor cooking?

[Wood, Cow dung, LPG, Kerosene, Gobar gas]

use of wood would lead to reduction of forests.

Cow dung leads to air pollution so its not eco friendly.


Kerosene and LPG are non renewable resources.


So one should use gobar gas (Biogas) for cooking since it is renewable as well as eco-friendly. It also lowers the greenhouse effect on earth’s atmosphere. And production of biogas includes conversion of natural organic waste into fertilizer.
