Is Ethanol Production Beneficial for ALL of Agriculture

So, the results are in from the quick poll I ran. 25% say ethanol production IS beneficial for agriculture and 75% say it is not. I am with the latter group. Ethanol in the US is primarily made from corn which is an agricultural product, seeming to make it, on the surface, a good thing. If we dig a little deeper, however, a monster rears its ugly head. Ethanol production is heavily subsidized by the US government. If this money is cut off, the bubble is going to collapse, simply because corn ethanol is not sustainable. It actually costs more to produce, in energy terms, than we get from it. There is also considerable data available that shows we will actually increase our carbon emissions by nearly 100% if we continue our current rate of land clearing for ethanol production. This is not good for anyone, whether they are a farmer, a rancher or an urban dweller. We should leave ethanol to Brazil. They have the right kind of plants to make it sustainable.
