[The Daily Star] Biofuel emerged as an alternative fuel to benefit the biotech companies and the trans-national corporations (TNCs) which claim that biofuel is a unique `green innovation’ of the modern technology sensitive to the environment, ecology and the poor. Refuting this TNC claim, reputed and established scientists of the world are saying that the TNC claim is contrary to the reality as biofuel production causes food scarcity and environmental degradation. That by propagating this, they are rather committing crime against humanity.
