In the "Death of the Family Dairy Farm" article that was on HN the other day, the clear trend was toward CAFO's (Concentrated Animal Feedlot Operations) - aka giant farms.

Along with these, there are really clear environmental impacts as the density of the herd/land is just overwhelming to the point where it's not "cows fertilizing the field" but being legally required to create massive manure lagoons, etc.

What's clever about the cow toilet is that it opens up new options for treatment of both manure and urine.

This is the article from the other day, find "manure lagoon" in it to see all the problems

There are places where animal manure is being used for the biogas production. The scale of the cesspool in the link is way above any small farm biogas tank, but then there must be better ways to speed up the biological decomposition of the manure. Mixing it with plant material, increasing surface and pumping air i.e.


Fascinating 2002 article that goes into a great deal of detail about CAFOs:

Yeah people need to let go of the idea of cute happy cows living free in grass planes. The drawing on your milk carton is far from the reality of these animals.
