Nic Marks: The Happy Planet Index on TED

Nic Marks: The Happy Planet Index - Statistician Nic Marks asks why we measure a nation's success by its productivity -- instead of by the happiness and well-being of its people. He introduces the Happy Planet Index, which tracks national well-being against resource use (because a happy life doesn't have to cost the earth). Which countries rank highest in the HPI? You might be surprised.
