Sustainability is not an individual property, but is a property of an entire web of relationships.

Fritjof Capra, PhD, is an Austria-born American physicist, systems theorist, educator, activist, and deep ecologist. He is the author of several international bestsellers that connect conceptual changes in science with broader changes in worldview and values in society. Capra is best known for his book The Tao of Physics, which explored the ways in which modern physics has changed our worldview from a mechanistic to a holistic and ecological one.
