I'm not sure that organic food can be classified as a scam. I think we have sufficient evidence of harmful chemicals, herbicides, pesticides, (remember DDT), that we might not know the true consequence for many years. Roundup is a current herbicide that everyone probably uses in some fashion. It is being used directly with seed corn that is genetically modified to resist roundup. So the corn grows, the weeds don't. How many years will it take to identify a problem? And how big will the problem be? At least with organic methods, we know they've been used for hundreds - if not thousands of years.
