The problem is that there are too many people

That's exactly my earlier point. We will starve before we run out of water, air, or land.

1). A lot of some human food can be grown in a small amount of space: World's first robot-run farm to churn out 11 million heads of lettuce per year | Inhabitat - Green Design, Innovation, Architecture, Green Building

2). Humans can (almost) substitute most animal for vegetable protein: https://www.healthaliciousness.com/articles/vegetables-high-in-protein.php

3). Smaller animal sources can replace larger animals: Insect protein ‘similar to conventional meat’

The future technology is out there for our later generations to survive.
(After every other life form has been scraped off the surface and depths of this planet.)
But will that be the world we envision? We want?

I thought we were all going to be roasted alive by Global Warming?

Warmer weather leads to longer growing seasons. Canada will pick up the slack when we don't have snow on the ground 8 months of the year.

The two biggest issue to overcome is clean water, and energy. It will take a LOT of power to keep everyone comfortable and have the ability to travel to and from work and still have a quality of life. We have a three bedroom howse and three cars between just my wife and myself. I will not be taking in boarders. We have the occasional guest spend time in the spare bedroom but it is empty 98% of the time. We have three cars and two drivers. I like it that way and I am just a horrible capitalist and have no intention of sharing. I pay a fortune in taxes as it is now. I will pay my fair share but no more.

Some think technology will solve the problem -

AI revolution, pt 1

AI revolution, pt 2

Coming Technological Singularity (from 1993 perspective)

Stephen Hawking on AI

Stephen Hawking on extinction

Here is a water and climate theory that has an interesting suggestion at the end -

Pacific NW as a draw for population migration

Sure there is lots of land out there... but as Java points out only a small percentage is livable... drive from Los Angeles to Las Vegas and there is a lot of desert... desert with little empty homesteading shacks... empty because there is no water and nothing will grow in the poor soil.

Las Vegas used to be "unlivable desert."

Same with Palm Spring, and actually most of So. Cal.

But that was all built with water from the central valley and the Colorado river... both of which are tapped out.

No Central Valley or Eastern Sierra (CA Aqueduct or Feather River project) water used in either Palm Springs or Vegas. Vegas was built on the Colorado River and some run-off from Mount Charleston. Both declining resources.

Palm Springs was built on the Coachella Valley Aquifer. It's a HUGE underwater lake fed by snow run-off from Mount San Jacinto and Mount San Gorgonio. The CVA is drying up so fast that half the 124 irrigated golf courses are in serious jeopardy. The Coachella Water District is now also fighting Vegas and SoCa for Colorado river water, along with the Imperial Valley farmers. So little water is getting below Blythe that in many places you can walk across the Colorado without getting your shorts wet.

I still believe MRSA will get us first, but a lack of clean water is a close second.
