Need to figure out How much land goes into feeding each person every year? "hobby Farmers" typically use more land per animal than factory farmers, How much more land would we need to use if animals were raised more humanely? Any random Facts, links, etc. to help me figure this out will be helpful... I'll be doing my own research too. How much corn does a chicken eat in a year? A cow? Anything is helpfull. Thanks, You guys are all ways really helpfull.
