Stella McCartney has always been at the forefront of  the green scene; she’s a lifelong vegetarian, does not use any fur or leather in her line and even sources a special plant that has a leather like substance for her shoes. She is not alone. McCartney has an army of A-list celebs supporting the cause and raising awareness for  environmental issues. On Friday her posse stood tall and chic for the screening of socially conscious movie Home, directed by Yann-Arthus Bertrand at her West Hollywood store to celebrate  World Environment Day.  Cameron Diaz, Liv Tyler, Charlize Theron, Rosario Dawson and many others wore Stella McCartney proving that it’s possible to look elegant, sexy, and stylish without harming the environment.  ~Adam London
