David Korten – has assisted in raising public consciousness of the political and institutional consequences of economic globalization and the expansion of corporate power at the expense of democracy, equity, and environmental protection. Korten is co-founder and board chair of the Positive Futures Network, which publishes the quarterly YES! Magazine. He is also a founding board member, emeritus, of theBusiness Alliance for Local Living Economies, a former associate of the International Forum on Globalization, and a member of the Club of Rome. Korten’s 2006 book The Great Turning: From Empire to Earth Community argues that the development of empires about 5,000 years ago, initiated unequal distribution of power and social benefits to the small portion of the population they controlled. He also argues that corporations are modern versions of empire, both being social organizations based on hierarchies, chauvinism, and domination through violence. The rise of powerful, advanced technology combined with the control of corporate- as well as nation-based empires is described as becoming increasingly destructive to communities and the environment. Korten postulates that the world is on the verge of a perfect storm of converging crises, including anthropogenic adverse climate change, post-peak oil production decline, and a financial crisis caused by an unbalanced global economy. This will precipitate major changes to the current economic and social structure. Korten believes that these crises will present an opportunity for significant changes that could replace the paradigm of “Empire” with one of “Earth Community”. Although recognizing the potential that the opportunity may not be seized, Korten hopes that this opportunity will result in the emergence of an “Earth Community”, based on sustainable, just, and caring communities that incorporate the values of mutual responsibility and accountability.
