New York City-based Colin Beavan, aka “No Impact Man,” inspired the masses — and raised a few eyebrows — when he bid adieu to conspicuous consumption (as well as toilet paper and electricity) and embarked on a yearlong project in 2006 that found him and his family living an off-the-grid existence in the heart of the Big Apple. Beavan chronicled his bold “experiment in lifestyle redesign” — described by some as an eco-stunt — on the thought-provoking No Impact Man blog. A book and a documentary film followed.
