Answer 2

$<b><i><u>$ First of all, let us know what is meant by fuels.

=> Fuel is the substance that is burnt to produce heat or energy.



Following are the disadvantages of fuels :-

1] When fuels burnt, they produce harmful gases such as carbon dioxide which can increase global warming.

2] When fuels are burnt, they release oxides of carbon, sulphur and nitrogen etc. They cause acid rains, which affect the soil fertility and potable water.

3] For fuels, the ground is being digged. It can be dangerous because if digged near a building, there are more chances of falling of that building.

4] Fuels are non renewable resources as they take number of years to form.
