Now here’s a cool concept. Why not add a new “green” element to soccer matches by putting a 10-meter high magnolia tree in the center? It would add a new element to the game as players could hide behind the tree for sneak attacks.
Chilean artist Sebastian Errazuriz planted the tree in the center of Chile's National Stadium where dictator Pinochet tortured political prisoners 30 years ago. For a week, the stadium was open to the public as a park, and the finale of the piece was a real soccer match played in front of 15,000 people.
