"We need to use fossil fuels judiciously." Justify the statement.

(N/A) $(i)$ Coal and petroleum were formed from the degradation of biomass millions of years ago, and they are non-renewable resources, meaning they will eventually get exhausted.
$(ii)$ When fossil fuels are burnt, they release harmful gases and particulate matter, which cause air pollution and respiratory problems.
$(iii)$ Fossil fuels are huge reservoirs of carbon. If all this carbon is converted into $CO_2$ through combustion, it will significantly increase the greenhouse effect, leading to global warming and climate change.
