People in the know have been saying this for years, so I don't understand why it's just now being discussed in popular media: Ethanol is not a solution for replacing diminishing fossil fuel supplies. If politicians continue to let King Corn continue his annexation and destruction of good land, and continue to praise biofuels as part of the long term solution to the coming energy shortage, being able to say I told you so twenty years from now will not be of any consolation. Even liberal estimates say that there's not enough arable land in the world for biofuels to feed the transportation energy needs of the U.S alone.
