GREENFIELD is an intimate look into the mind and mission of Robin Greenfield — one of the world's most radical environmentalists. Known for his bold eco-experiments, including wearing a month's worth of trash through Times Square, living a full year on only homegrown and foraged food, and giving up every possession, Robin challenges what it means to live in harmony with the Earth. As he walks barefoot from Canada to Mexico releasing every material item, his radical simplicity invites us to question what we truly need to be free, fulfilled, and human.
