I've been against GMO labeling for the same reason I'm against other seemingly nonsensical/irrational-fear-based labeling (I wouldn't want all food manufacturers to have to label foods manufactured by immigrants, or within 100 miles of a Native American burial ground, or on a Friday the 13th, for instance). It has the capacity to scare people, and introduce new obstacles between food producers and hungry mouths for no useful reason.
Also: like almost everyone here, I'm against Monsanto's business practices, and would really love to be able to agree with peer-reviewed scientific findings without being ad-hominem "agreeing with agribusiness and Frank Blethen", implying that I agree with them on other subjects, which I don't.
I highly dispute the idea that GMO farming is "environmentally disastrous". Without a widespread plague, genocide, or other significant depopulation, organically-grown food would not EVER feed the humans that exist on the planet currently, much less in the years to come. Non-GMO "organic" produce is a completely unnecessary first-world luxury item, and anything that implies that it's the direction we should be going in is irresponsible or entitled, naively proclaiming "Let them eat organics!"
ALL THAT SAID... My friend Mez finally articulated the pro-GMO + pro-labeling argument
in a way that finally convinced me that it's a good idea. SO, yes, let's get this part of the discussion over with, and focus our energies on something worthy of our outrage. I'm sure if we think really hard, we can come up with *something*...
