Paul Hawken is an American environmentalist, entrepreneur, author, activist and the Co-founder and Executive Director of Project Drawdown, a non-profit that describes how global warming can be reversed. He was the lead author on the book Drawdown as well. Hawken has authored articles, op-eds, and peer-reviewed papers, and has written seven books, including: The Next Economy (Ballantine 1983), Growing a Business (Simon and Schuster 1987), The Ecology of Commerce (HarperCollins 1993), and Blessed Unrest (Viking 2007). The Ecology of Commerce was voted the #1 college text on business and the environment by professors in 67 business schools. The businessman and environmentalist Ray Anderson of Interface, Inc. credited The Ecology of Commerce with his environmental awakening. He described reading it as a “spear in the chest experience,” after which Anderson started crisscrossing the country with a near-evangelical fervor, telling fellow executives about the need to reduce waste and carbon emissions.
