unless one lives in Iowa. I hope you like corn.
I live in IA, and I likes me some corn. I've lived in Texas and AZ too. It's easy to be a locavore in TX and IA with all of the local grown and raised foods.
Not so easy in Phoenix AZ. The local agriculture (mostly roses) puts a strain on the available water supply. I wouldnt be surprised if the local ag is out of Phoenix in the next 10 years, due to the growth in and around the city.
If you want to reduce waste, buy local veggies, and eat organic or free-range chicken. Chicken has a high feed to pound of lean ratio. Hatch to the table in about 6-8 weeks.
Go to an average chicken farm a few times and you will start to taste the difference in the meat. The litter is rarely changed, due to cost reduction, and the meat begins to taste like the farm smells. Picture 50,000 birds sharing a 50,000 square foot chicken house with a new batch every 8 weeks. Now put 6 of those houses on one plot of land. Smells a bit, though some say that's the smell of money.
Kosher is good too. Strict religious guidelines to from start to finish.
BTW Free-range, Organic, and Kosher are expensive, so just keep on going to wal-mart and buying the sams choice value packs.
