Greening cities

Singapore's Gardens By The Bay greens the city while bringing residents closer to nature.  Supertrees, made from concrete and steel, house thousands of plants.

Milans' Bosco Verticale consists of twin towers planted with 700 trees and thousands of smaller plants.  The vegetation creates an ecosystem supporting wildlife and absorbs CO2.  

We in New York have Central Park, our 778 acre backyard in the middle of super prime Manhattan.
