26 years ago, the founder of TrueSchool wrote a manifest. A study on the practical application of Treehouses for urban development, but also a paradigm for 3 things required to save life on this planet:
Green Economic Zones, targeting Reclamation of Ecosystems.
Green Cities based on fully self-sufficient buildings including production. This requires affordable prototypes of buildings suitable to become the mainstream architecture in all parts of the world.
Fully automated mass production and new materials: fiber reinforced concrete and plastics, timber substitutes (like from straw), Bamboo, new alloys etc.
