The Germans were correct in using gas, but chose an inappropriate gas. Expensive, painful, allows the walls to be desecrated by the rodents.
I think merely CO en masse would work just fine, be relatively painless, and quick. I guess the real tough part would be disposal of the remains. How about a big mulch pile? I guess that leaves a lot of bones, but the pigs could use ground bone meal. Or something. I suggest at least 1% of the world's population. Can I get an ETA on when these disposal facilities could be built. I'm dead serious. I want to be the ribbon-cutter at the ceremony. Mark
