And where excess energy was being lost by lack of completely effective storage methods, people were finding more ways to use it while they had it: for desalination, or more direct air carbon capture, or seawater pumped overland into certain dry basins, and so on. On and on and on it went. So clean energy, the crux of the challenge, had been met, or was being met. Then also, another great poster: the Global Footprint Network had the world working at par in relation to the Earth’s bioproduction and waste intake and processing. World civilization was no longer using up more of the biosphere’s renewable resources than were being replaced by natural processes. What for many years had been true only for Cuba and Costa Rica had become true everywhere. Part of this achievement was due to the Half Earth projects; though this was not yet an achieved literal reality, because well more than half the Earth was still occupied and used by humans, nevertheless, broad swathes of each continent had been repurposed as wild land, and to a large extent emptied of people and their most disruptive structures, and left to the animals and plants. There were more wild animals alive on Earth than at any time in the past two centuries at least, and also there were fewer domestic beasts grown for human food, occupying far less land.

Most biomes were mongrels of one sort or another,
