However for developing countries where annual income of a farm of 1 ha could be less than 50 dollars due to rainfed conditions growing local plants could be an answer to findout biofuel. Growing biofuel plants can only protect total destruction of forests as for India a population of 100 million out of which at least 50 million cook their food on firewood purchased or stolen from forests legally or illegally would lose its forest cover in less than 30 years if no biofuel crops like local crops or plants replace forest plants for fuel.
