The global economy is unsustainable because it promotes constant growth on finite planet. Driving the expansionist economy is an unsustainable consumer culture. Because technological advances cannot solve social problems, within a few decades increasing resource shortages and degrading ecosystems will collapse the world system. Sustainability requires social and environmental resilience, health and wholeness. A consumer society cannot transform into a conserver society without cultural and structural change. The key factor for transformation is emergence of an integral worldview capable of organizing sustainable social structures and economic processes.
