As the Author of Force of Nature, Edward Humes reveals the inside story of the struggle to redefine what it means to be green in the world of big business through the lens of Wal-Mart's transition to becoming a green business. Humes brings his decades of writing and research experience to the topic, revealing the fact that the clean, green, efficient, less polluting way of doing business can also be the most profitable way of doing business. It's just one stop along his journey to take readers inside worlds most don’t get to visit or see close up on their own.

Humes' latest books are Garbology: Our Dirty Love Affair With Trash, and A Man and His Mountain: The Everyman Who Created Kendall-Jackson and Became America's Greatest Wine Entrepreneur.
