Why use of bio-fuel/biomass is better as compared to fossil fuel ?

Explanation

Fossil fuels are exhaustible or non- renewable sources of energy. It will get depleted some day. They also cause heavy pollution. So we cannot depend on the fossil fuels for much longer.
On the other hand, if we use biomass, the trees are cut down for fire wood. But by using gobar gas as a bio-fuel, we can get constant supply of energy at a particular rate. Such energy sources can be regenerated, so called renewable sources of energy.
So, compared to fossil fuel, use of biomass is better.
