Biofuel good after all?

Biofuel has been heavily criticized for taking up agriculture places, where food used to be grown, and so leading to higher prices for food. It also would cause deforestation.

But a report in the news shed a different light. Scientists are working hard to get biofuel out of agricultural waste, and are making good progress. Therefore it seems that biofuel competing with food is just temporary; once we can make biofuel from agricultural waste, food prices would go back to normal.
