Co-Existence Model of Ecologically and Socially Sustainable
Earth. (updated draft of "'Evolving' the Ideal Earth Design:
Ensuring Transparency".) by Mr. Jan Hearthstone. There exist
many notions of what a sustainable world should look like with
no clear consensus on the subject. It would be possible to
accommodate any sustainable life-styles of varying degrees of
complexity on Earth--all those could exist in the world without
interfering with each other, and without interfering unduly with
other life forms that share the Earth with humanity--providing
that all those life-styles would be demonstrably sustainable. It
would be possible to model this situation perhaps not even
needing any extensive computer modeling--"gedanken
experiments"(notes) might even be enough, at least at the start;
computer modeling might, perhaps, be used later for proving that
the more complex sustainable life-styles would, indeed, be
sustainable. To ensure that any style of a sustainable living of
any degree of complexity would really
