Would there be enough resources to sustain 100+ billion people?

No...which is why Soros, Gates, Rockefeller, Rothschild have used GMOs, Fluoridated Water and Vaccines as ways to depopulate slowly........

2016

The W.H.O. has estimated that current world resources
can sustain 21B people.

As technology develops and we are able to make better
use of our resources this cap shall increase.

Sorry I don’t have the link.

Considering million die today from lack of resources and there's 7 billion people, I'd say no. In nature, when there's too many of an animal, there is a big die off until sustainable populations are reached. We by-pass this processes. Eventually, it will catch up to us. Simply cutting off electricity will have greater and greater consequences in the future.

Soylent Green! It's... People!!!

[Sorry: uh... Spoiler Alert]

Not at all

Possibly, but not like we're doing it now.

Rrrr

Probably. I mean, resources can be created.
The real question is whether the management is up for the job.

In a food cloned world possibly.
