Reply #9: One evil irony is that all that pig shit can be turned into money,.. [View All]

...Disposing of it need not be a cost at all. With bio-reactors it is possible to extract a good deal of energy from that much pig shit, plus a lot of sterile fertiliser, and return clean water to the piggery. Offal from meat works can be disposed of the same way.

The sad truth is that this sort of "farming" is not going to go away, the best that can be hoped for is to improve conditions for the animals and the workers. And flow on environmental effects should benefit all regardless.
