Vegans love to talk about how “sustainable” their lifestyle is. I can buy a lamb in the spring and let it graze all summer. Then I can have it butchered in the winter (so I don’t have to feed it) and it can feed my family over the winter with the grass that it ate in the summer. No airplanes or ships (or lawnmowers) required.

Then there is this bit from George Monbiot: “Feeding meat and bone meal to cows was insane. Feeding it to pigs, whose natural diet incorporates a fair bit of meat, makes sense, as long as it is rendered properly. The same goes for swill. Giving sterilized scraps to pigs solves two problems at once: waste disposal and the diversion of grain. Instead we now dump or incinerate millions of tonnes of possible pig food and replace it with soya whose production trashes the Amazon".
