Neat idea, but I'm not sure I want to smell the manure left my neighbors livestock. In Manhattan, most people would not have a yard into which they could create such an environment.

I do like the idea of the show because many people who live in urban areas have no skills that they could rely on if they needed to raise anything more than their hands. I cannot tell you the last time I met a woman who could spin yarn. I know I do not know many, women or men, who can knit or sew anything worthwhile. I also have an inkling that people posting on this forum are more likely to have these skills.

As far as the pond, one might be able to get away with something much smaller with a different fish. Someone has apparently raised channel catfish in a barrell, feeding them worms raised on table scraps. See: http://www.kurtsaxon.com/foods007.htm.
