This piece in the New York Times should be of particular interest to environmentalists, because the pig industry is one of the most environmentally destructive in the nation. In addition to the need for massive regulation of the seas of manure these factory hog farms generate — which often end up in rivers and streams and foul the air for miles — the animals are subjected to absolutely horrific conditions. We should demand environmental improvements and humane treatment in our nation’s factory farms. I think the environmental community can reasonably get behind both of these measures.
