Some environmentalists hate ethanol; they say that ethanol is terrible for the environment.
For instance, the runoff from corn fields create "dead zones" in rivers, lakes, deltas, and oceans near coastlines.
Furthermore, in order to produce ethanol, a lot of corn must be produced, using exorbitant amounts of water and other natural resources.
Therefore, ethanol creates huge environmental problems. It is more expensive than oil in many ways.
You really don't know a whole lot about growing corn , do you?
