I did a CORNy drawing today....
The Obnivore's Dilemma delves into big business agriculture and the historical use of corn as the tool against those who first cultivated in order to eradicate them from existence. Corn is a high yielder. It produces far more 'product' than wheat with a 300:1 ratio for intensive seed production (it can flourish in the crappiest of soils) and it's ability to transform carbon from the air as no other grass can. We can't live without it, but then again corn cant live without us either. I find it interesting that corn's biology won't allow it to survive if not for it's symbiotic relationship with mankind.....and maybe a few corporate patents.
Corn reorganizes itself back into it's original form after you eat it - weird.
