"Guerrilla Grafters Secretly Graft Fruit-Bearing Branches onto San Francisco Trees"
That's really neat. Start with a forest, end up with an edible forest:
For the past two years, a group that calls themselves Guerrilla Grafters have been secretly grafting fruit-bearing scions onto ornamental, non-fruiting trees in San Francisco. City officials contend that Guerrilla Grafters are breaking the law, but their actions have been celebrated by proponents of urban agriculture. And they have been included in the US pavilion’s Spontaneous Interventions exhibit at the Venice Biennale.
Moar "spontaneous interventions" like this, please.
