londoners love their little parks - a small amount of greenery amongst the otherwise grey streets.

however, this feeling is obviously not shared by everyone. in particular the plant activists. they are sick and tired of plants being treated like caged animals and want their plants liberated to roam free in the countryside.

of course these liberators don't want to ruin the environment so have chosen to state their views on a piece of paper cellotaped to a sign at the entrance to the park.

(the views expressed here are not necessarily my own. i am prepared to believe that a plant, properly fed and watered, and sheltered from frost can have a perfectly happy life in an artificial environment)
