Many studies have tried to estimate the world's sustainable population for humans, that is, the maximum population the world can host. [5] A 2004 meta-analysis of 69 such studies from 1694 until 2001 found the average predicted maximum number of people the Earth would ever have was 7.7 billion people, with lower and upper meta-bounds at 0.65 and 9.8 billion people, respectively.

[50] [5] This suggests that 8 billion people may be sustainable for a few generations, but not over the long term, and the term ‘carrying capacity’ implies a population that is sustainable indefinitely. It is possible, too, that efforts to anticipate and manage the impacts of powerful new technologies, or to divide up the efforts needed to ...

If Leonard Cohen built a tower of just one song, it was “Hallelujah” — the subject of a film that hits theaters in July, “Hallelujah: Leonard Cohen, a Journey, a Song.”
Wonderland is a compact model. In total, there are only four continuous state variables, one each for the economic and demographic sectors and two for the anthropogenic sector; thus making Wonderland more compact and amenable to analysis than larger, more intricate models like World3.
