Too much of a good thing

Corn was one of the three sisters. Corn Beans and Squash, the staple vegetables of native agriculture in the Eastern U.S. Back then it's storability and high caloric density made it an essential crop for life in the rugged American landscape. Now we see it as an enemy.

Its all a matter of scale. Why are there huge tragedies? Because there are huge countries. Why are there huge environmental problems? Because we have huge economies. Why were there huge 4and a half billion ears of corn harvested in Iowa this year? Because there are huge subsidies that make this unfeasible crop into the best case scenario.

Reasons I'm opposed to Corn:
(1) Corn is being grown mainly for cattle feed and it's unhealthy for the cattle and those who eat the meat
(2) Corn is being grown in a big way to produce ethanol, an alternative energy that is extremely unsustainable
(3) Corn is not eaten whole. It is eaten at the molecular level.
(4) Corn takes a ton of fertilizer which contributes to global warming.

Explanations:
(1) Again, its a matter of scale.
Feeding grains to cows is pretty standard, at the rate of one or two scoops a day. That's why we have silos, I guess. But it's well known that if a cow gets into the silo, it will gladly eat itself to death! That's too much grain. Turn a cow out onto the pasture and it can't eat itself to death. Grass fed beef and bison are the way to go. That or wild game.

(2) Ethanol production is a bad idea. Growing forests sequesters more carbon than Corn fields do. If they could make ethanol from cellulose it would be worth it. Until then, leave ethanol alone. The equation doesn't balance.

(3) Corn products are lame. Aren't Americans sweet enough without them? I can't wait until the days when most foods have a list of actual ingredients on the label rather than a list of chemicals.

(4) Corn requires MASSIVE inputs of fertilizer from year to year. Nitrogen is the plant's limiting nutrient. This element is a very mobile element though, since it has several gaseous phases that it can transform between by means of microbial processes. Nitrous Oxide, NO2 is a biproduct of fertilizing with Nitrogen. NO2 is released in significant quantities to the atmosphere during ethanol production. Each molecule of NO2 is 25 times more effective a greenhouse gas than a CO2 molecule. Put that in your pipe and smoke it! Actually don't smoke, you're hurting the environment.

"But Adam!" you say. "80% of the Atmosphere is already Nitrogen! What difference does it make to add more?"

"Well, I'm glad you asked." I reply. "Most atmospheric Nitrogen is N2 which is an extremely stable molecule with a triple bond. NO2 is a different molecule with different properties." for example it has the capacity to FRY THE EARTH."

But it's still a matter of scale. Corn can be grown sustainably through crop rotation or fertilization on a smaller scale. Is the world's population at fault here? No. The earth can sustain this many people I believe. But not these people.
