From my understanding (which could be complete and total junk science/quackery)... wheat and other vegetables are carbon neutral. CO2 is extracted from the atmosphere, and used to grow the plants. Even unused parts (wheat straw) are a type of carbon "sink" in that the atmospheric carbon is trapped in organic matter which can be "upcycled" into paper products, etc. I believe this thought process is why corn-ethanol was so hyped, as it was sold as a 'net carbon zero' fuel. Not looking for a flamewar here, and I would be grateful if you could correct any misunderstandings I may have. I've got an 8th grade science-fair level of education on this one, so I'm more than open to your thoughts!
