I'm talking networks of buildings over a mile high - harvesting solar power, sunlight, wind and water. Powered by a combination of that and offshore wave power and perhaps trigeneration plants and geothermal heat cycling in each major building.Access to space and sunlight would be far superior to today. Vegetation would drape down the buildings on the side opposite to the sun. Vegetables/food would be grown in part in vertical farms within the building, and in individual and communal gardens at all levels of the building. Convection (stack effect) would be harvested for cooling and power, as would falling (under gravity) water.Essentially I am talking about something totally visionary and different to what we have today. These crystal cities would be surrounded by parkland, entertainment and cultural precincts, beaches, sporting fields and arenas etc. We would still be able to access camping and walking trails etc in national parks as now. I imagine there would also be very small amounts of sustainable suburbia type living where those areas offer highly desirable things like views etc, though 90% of the worldwide urban sprawl that we see now would be returned to fully functioning wild nature.Similarly a lot of the agricultural and grazing lands would be restored back to nature (particularly along the riparian and wetland 'lungs' and 'arteries' of the land. The rest would be run along regenerative agriculture and sustainable practices (see S McIntyre et al.)  I imagine those working on the small area of land / national parks / sustainable native forestry plantations / conservation / restoration / tourism works would also live in small appropriately located communities. For those that would go absolutely mental without space and silence, I imagine they would gravitate to these jobs / areas - pretty much as they do now. If that's too many people still - then there's always Antarctic Research or even Space Travel / Colonization!I take the point about cultural proclivity to such close quarters living, but really I am imagining a vastly superior situation to today. I  think those stuck in the traffic jams of suburbia would flock to a better form of living.It is interesting that when I was at Uni, the industry was opened up to full fee paying global students. Those that were from Asian backgrounds showed a distinct preference for living cheek by jowl in high density apartment living - even when given any alternative choice.At the moment 99% of NSW is in drought - the historical ways of farming / grazing just won't cut it. Unless we restore the entire Murray-Darling wetland and soil moisture storage system with continual vegetation cover  .... we're stuffed. There is one progressive young(ish) farmer who I have met, who once again is ahead of his time and a global innovator - Nigel Kerin   <a href="http://www.abc.net.au/news/rural/2018-08-12/defying-and-overcoming-the-nsw-qld-drought/10084358" target="_blank">http://www.abc.net.au/news/rural/2018-08-12/defying-and-overcoming-the-nsw-qld-drought/10084358</a>The current trajectory is unsustainable - this proposal is the only hope for our wildlife and natural ecosystems that I can see. A massive change for sure ..... but the alternative doesn't bear thinking about ......Chosun   :gh:</blockquote>
