Ethanol is great in theory, but the amount of energy (and fossil fuels) that go into growing corn and converting it to ethanol are huge. You don't get far ahead. Could we study ethanol from non-food crops (eg switchgrass)? Or could we use some of the taxpayer funded corn subsidies and use it towards development of alternative energy, better hybrid car batteries or something similar?
I live out in the boonies, and I see firsthand what's needed to produce corn. Commercial agriculture is an *industrial* operation which produces quite a bit of pollution/byproducts. Fertilizer run-off alone is responsible for tainted drinking wells, fish die-offs, and now on a large scale ocean dead-zones. Modern US farming is agri-business, not the pretty green natural thing it appears to be on TV. So if we're pushing US farmers to up production, we're also seeing more marginal land pushed back into tillage, more fertilizer/pesticide use, higher demand on freshwater as more fields are irrigated, etc. How good is it for the environment if we're draining rivers and then refilling them with run-off tainted with nitrates, phosphorous, and heribicides?
Don't hate me but I think $4/gallon gas has been really good in a way. Suddenly high mpg cars are "green" and dealers can't keep them in stock. Windfarms are sprouting up all over. More R&D money is going into solar, which is getting cheaper. People are finally starting to think beyond fossil fuels.

Are you saying development is good for the ecology & air quality ???

we are using trends based on samples taken in the last 50 years - way less than 1 millionth of our 'production'. Try that on any production QC standard.

I respectfully disagree. Glaciers,
such as those in Greenland, are excellent for study and tell us quite a bit about climate tens of thousands of years ago.
