More oddity

I'm not sure that I've quite read George Monbiot properly here.

Or you could become a guerrilla planter or guerrilla grafter, growing fruit on roadsides, on commons and in parks and wasteland. Apple twigs of any kind can be grafted on to crab trees. Medlars and one breed of pear (a delicious variety called Joséphine des Malines) can be grafted on to hawthorn.

Grafting...isn't that the mixing of two species? That thing that we're supposed not to do when we call it GM?
