The perfection of hunting spelled the end of hunting as a way of life. Easy meat meant more babies. More babies meant more hunters. More hunters, sooner or later, meant less game. Most of the great human migrations across the world at this time must have been driven by want, as we bankrupted the land with our moveable feasts.

Benjamin Disraeli had anticipated Erewhon’s fears in his novel Coningsby: “The mystery of mysteries,” he wrote, “is to view machines making machines, a spectacle that fills the mind with curious and even awful speculation.

Like most problems with technology, pollution is a problem of scale.

Just enough greyhounds catch a real hare now and then to keep the others running till they drop. In the past it was only the poor who lost this game; now it is the planet.
