The world has become very dependent on carbon-rich fossil fuels over time because of its high calorific value. This means that it produces a big amount of energy when it undergoes combustion. However, the by-product of combustion of carbon is carbon dioxide. It is a known greenhouse gas and pollutant. This is the risk the scientists fear that might affect the environment in the long run.
