When Colin Beavan embarked upon a yearlong experiment to lead a zero net-impact existence in the middle of New York City, he had no idea what a profound effect it would have upon himself and others around him. For Colin, the project—chronicled in a book, a documentary, and an ongoing lecture series—formed the basis of a radical “lifestyle redesign” that reached beyond just environmental activism.

In this conversation, Colin will explain how to invite small changes into your life that will make you feel more alive and joyful, while also participating in the kind of transformational happiness that helps the world.
