A six-part series about international efforts to design and build eco-friendly structures through sustainable architecture.

The series begins in New York, a city that is leading the charge to green its skyline with several groundbreaking projects. New York debunks the myth of the "concrete jungle," proving that dense urban environments can be inherently sustainable. "The Green Apple" explores some of Manhattan's most prominent and technologically advanced structures - like One Bryant Park and The Solaire - and features interviews with architects Robert Fox, Richard Cook and Sergio Palleroni, among others. The episode illustrates how the ubiquitous skyscraper can be designed as a model of environmental responsibility.—Anonymous
