The vast majority of people don't realize that terrible treatment of animals in factory farms and our agrictultural policies actually have seriously negative consequences for consumers and society overall.
Some of this was discussed the other day in the ReThink review of King Corn (a movie I watched a month or so ago) where they discussed how corn has made it's way into EVERYTHING and how that's greatly contributed to the obesity epidemic.
And the quality of the meat we eat in terms of nutrient composition (particularly fat composition) has degraded significantly due to factory farming practices. Not to mention the fact that around 3/4 of the antiobiotics used in the US are for farm animals. Not to mention things like swine flu and mad cow (and other terrifying prion related conditions we just beginning to learn about).
The point is that even if you're a selfish conservative/libertarian prick, there are selfish health/public safety reasons to seriously reconsider factory farm/agrictultural practices.
Easier said than done I know, believe me. Part of me really wants to see the newly released Food Inc., but another part of me wants to remain ignorant of the true horrors of food practices...
A conservative believes nothing should be done for the first time
