The problem with every company pursuing yield over everything, is that the amount of vitamins/minerals per acre hasn't changed, so you get 1/10 the nutrition in every cob of corn. Also, the pesticide they use has to be stronger each year as bugs become immune- what happens once we can't make it any stronger? If the GMO spreads so easily, then how will any heirloom varieties survive?
All but the last of those questions were asked in my Biology class last year.
I don't know if it was because I watched one too many Doomsday preppers, or my natural paranoia, but my 'end game' is to have a virtually self- sufficient farm, maybe selling a few things here and there to support animal rescues.
Fast food isn't jsut because people are lazy- they don't know how to cook. I'm in a 'healthy cooking' class at school, and there are 5 groups. Only 3 were able to make a simple recipie without any issues. About 10 people didn't know what zuccini were, and 3 didn't know what flour was. Half the class didn't know how to make a baked potato. Almost 3/4 didn't know how to grate cheese. I could go on. And these are high school students.
