Fuelling debate

摘要

Your article is an example of how society fails to properly evaluate the technologies needed to fight climate change ("Biofools", April 11th). Instead of identifying the best solutions, you focus on a worst-case scenario and reach a misleading conclusion. The problem is not biofuels, but agricultural methods in general. In fact, biofuels can actually have a positive impact on agricultural emissions. When the benefit of animal feed by-products resulting from biofuel production is taken into account, there is an increase in yield from an acre of land and required fertilisers.
