Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Rural regions account for 43 percent of the world's population – estimated to be just over 8 billion, at the last count – and if the calculations in this new study are correct then the number of unaccounted-for people could potentially stretch into the billions.(...)

"We were surprised to find that the actual population living in rural areas is much higher than the global population data indicates – depending on the dataset, rural populations have been underestimated by between 53 percent to 84 percent over the period studied."(..)

ad: "Not everyone is convinced. Scientists who weren't involved in the study told Chris Stokel-Walker at New Scientist that improvements in satellite imagery and the quality of data collecting in some countries would make these discrepancies smaller."(..)

I don't like living in a dense urban area, but undoubtedly it is the way to keep the planet healthy and us alive.

Vertical farming and efficiencies of providing services to denser areas, along with re-wilding areas for carbon capture all seem like part of the puzzle.

In the real world though, how do you get the entire population of the US to move to a handful of cities?

How would we even pay for the infrastructure development with our current model of building it and then ignoring it until we have to put a bandaid on it

Yeah, I don't see us all moving into cities, although many people already have. I also don't think we need to have one giant city - those numbers were given to show how little actual living space people need, keeping in mind that Paris doesn't seem to be viewed as somewhere undesirable to live, and still has room for beauty and not just urban utilitarianism.

On the flip side, many people who move to the city do so for work. I hope we see less of that, where things can be more decentralized so people who like a less urban environment can still effectively contribute to society and the economy without having to stifle their personal living preferences. I'd also like to see less cost-efficient but more space-efficient growing conditions for agriculture so more land can be returned to a natural state while still supporting the populations we have. Both vertical farming and vertical living can contribute to that. And I absolutely realize that livestock tend to be both less cost- and space-efficient, especially if it's humane.

Yeah, the only way I see reducing livestock is if the cost gets unacceptable for the working class. Nobody wants to hear "you need to eat plants". Would require a culture shift in the US at least

Chickens are surprisingly effective as far as meat animals go.

I'm super interested in insects too. Im growing spirulina right now to experiment if it can be a protein source
