@Thomas,
I'm very interested in the results coming out of the zero waste farming movement research.
I did my vegetarian time, am fascinated by the studies by the high environmental costs of the 100 mile diet, and think it's now time to take the zero waste group seriously.
I'm trying to track down an interesting interview I listened to recently on the subject.
It's basically larger-scale versions of traditional farms - red meat/poultry/veggies all growing together with fish and bacteria as the additional factors.
