I have no idea who produces these crappy "public interest" programs on PBS TV, but I just watched one on organically grown foods which was filled with utter nonsense. They made the claim that if you ate organically grown foods you would feel better and be healthier. That's crap, pure and simple. Your body can't tell the difference between a protein from an "organically" grown food from one that comes from a big farm that uses commercial fertilizers. The plants themselves can't determine the origin of their NPK (nitrogen, phosphorous, and potassium), whether it be from cow manure or commercial fertilizer (which has a huge percentage of human waste in it these days). Didn't any of the present day people take chemistry? Do they think about what they hear on TV?
What is the purpose of this kind of "green" garbage info anyway? Do the greenies really believe we can feed America with only "organically" grown foodstuffs? If they do, they are dumber than dirt. By the way, it is all organically grown, unless one knows another way to do it - like "poof"!
By the way, did you know that a McDonald's Big Mac meal comes primarily from corn? A soft drink has more corn in it than anything else but water - by far. The bun is made from corn, the meat is grown on corn (and antibiotics to compensate for the high corn content of the feed), and the French fires are cooked in corn oil (source of most of the calories in FF's). The sauce is mostly corn products. So, enjoy your corn at McDonalds.
By the way, do you now understand why making ethanol from corn drives up the price of food? Stupid is as stupid does.
