Timothy Gieseke envisions the next Green Revolution supporting both economic and ecological worlds. To do so, the market must generate signals that demand ecoservices, such as clean water, air and habitat, along with the demand for food, fiber and bio-fuels. As governments and non-profit organizations struggle with defining "sustainability", EcoCommerce 101 recognizes that as economic participants, you and I, always have and always will define "sustainability". Using agriculture as the prime example, he employs actual and visionary examples of how an "ecoservice" market signal and an "invisible hand" can assure that our planet that will provide all our needs for the next millennium. EcoCommerce principles applied to retailing or water services could mean the emergence of a truly-green global economy; one which would be based on investing in ecosystem management and restoration.
