it will take years before ethanol can
fully replace oil because basically everything runs on gasoline

it would require almost a one-third of U.S.
farmland, to power one in 10 of America’s cars

So if ethanol fully replace oil, it going to be an unprecedented impact on the lands. And not only on lands. More and more fertilizres will be needed. More and more minerals will be extracted from mines, causing tremendous impact on underground environment and landscapes.

Ethanol is NOT THE ANSWER

That's me point.
