Re-watching Majora Carter reminded me of another project committed to green spaces in the inner city; Guerrilla Gardening, people who go and garden in neglected public spaces, without permission but with generosity and humour. They find abandoned, unregarded bits of urban environment, sneak in at night and do some  planting, some maintenance and eventually some harvesting. The idea has a distinguished history but has re-emerged in mainstream media through the efforts of a small band of gardeners in London, and around the world.
