I'm in a meeting for a whole day and thread goes to hell.
Grass fed vs. corn fed isn't the argument we should all be having. I'd aim more at grass-fed, less grass-fed, or without meat. Corn-fed is destructive on so many counts, not the least of which is the damage done by growing all the ugly corn to feed the cattle. The damage starts there, proceeds through the factory farms, and continues on into the ingestion of the meat and the run-offs produced at every stage.
Sorry that good animal husbandry is expensive, but the good news is you don't actually _need_ it.
