Coal reserves are said to be enough to last for another hundred years. Do you think we need to worry in such case why or why not?
Coal reserves are very limited. A coal reserve lasts approximately 100 years only. By the speed humans are consuming coal, there's doubt if it lasts for 100 years now.
The field of coal consumption is increasing rapidly. From small houses to big factories and power suppliers are using coal prominently. This is resulting in the scarcity of coal. It takes millions of years to nature from this fossil fuel inside the earth. But the consumptions are too high that it would not last for long.
That is why we should use coal with care and responsibly. Apart from that, we should use other renewables forms of energy.
