Question

fossil fuel will last only for few hundred years. why?

Answer 1

Fossil fuel is the fuel we get from constant decaying of living tissues in thousands of years. That is, if we were to get the fuel out of a dead body now, we will have to wait for thousands of years for it to become fuel. But the rate at which we are consuming it is very very fast and as it is in a limited quantity, it will deplete in a few hundred years or even less.

Answer 2

Natural resources are available for us natural.With out natural resource we cannot lead our life.It has been divide into two categories

1.Renewable resources and

2.Non-Renewable resources.

Renewable resources are the resources which can regenerate once again.eg:water,soil,etc.

Non-Renewable resources are the resources which we cannot regenerate when once it is utilized. eg:Fossils fuels

So once the fossil fuels used cannot regenerate eg:Coal,Petrol,Diesel etc

So it has to be conserved ,even for future generations.If it is not conserved,then after few years these fossil fuels become extinct.
