Price of oil goes up, and then so does the price of ethanol. As the price of ethanol goes up, so, therefore, does the price of corn or sugarcane from which ethanol is produced. As the price of corn or sugracane goes up, farmers convert more of their fields to the production of those crops rather than producing grain, etc.. The more farmers that do so, there less food is available on the market, creating inflated food prices due not only its shortage, but also the higher transportation costs due to the higher price of oil / ethanol / gasoline.

/Panda should be glad, he supposes, that humans aren't making ethanol from bamboo.
/Panda wonders if the humans are embarraced by their stupidity and what is clearly the failure of their so called 'civil' lization.
