Notes:
"Sustainability is not about sustaining development, or economic growth or competitive advantage.
What is sustained in a sustainable economy is the web of life on which our long term survival depends.
Technology, social institutions and our way of life must honour and support and co-operate with nature's inherent ability to sustain life.
Leaves, cells, communities are all living systems - systems within systems.
Difference between living and dead system is "the breath of life" - metabolism.
The flow of energy and matter through a network of chemical reactions that enables the living organism to maintain itself, regenerate itself and perpetuate.
Networks are the basic organisation of life.
The material, the cognitive and the social systems must integrate.
The key challenge of this century is to build ecologically sustainable communities that do not interfere with nature's ability to sustain life.
This will take collaboration - a unified material framework. The natural sciences, the social sciences and everyone else must work together."
