Progress throws up some startling images, and for my money this is one of them. It’s a 26-storey pig farm and slaughterhouse in Hubei, China. In the supply-and-demand scheme of things it’s probably a very reasonable development. It makes good use of technological and engineering capacity, provides for cost-efficient protein production, and could be said to have an environmentally friendly footprint compared with more land-intensive ways of growing pork. But something jars, doesn’t it? Like a sourness in the viscera. Something’s not right, and it feels like a sign. A sign, I suggest, of catastrophic disconnection.
