Corn Gasoline = SMOG!!

Yup.  Corn-a-holing the USA has produced more smog than if we left the damn gasoline alone.

...The bigger surprise is the fact that ethanol production and combustion significantly increases the production of nitrous oxides (Nox). This combines with oxygen in the atmosphere when exposed to sunlight, producing ozone. Now, when we have ozone far up in the atmosphere it helps shield the planet from the sun’s natural radiation, which is a good thing. But ground-level ozone produces no such benefit and actually contributes to the formation of smog and leads to respiratory ailments for many people....

"Respiratory ailments."

Notice that a lot more than the usual percentage of young children seem to have allergies in the last 10-20 years?

Huh.
