alt Hacker News> My one hope for AI, robotics, self driving cars, is that they can enable people in cities to migrate back to rural places.
Wouldn't it be better, at least for the Earth, for everyone to live in cities? This way, more of the world can remain fairly untouched by humans, and it could still remain easy accessible from the city for recreational purposes.
The solarpunk ideal of living a rural life requires more road infrastructure, which cuts off wildlife routes and natural drainage, and even with EVs, still pollutes the air from tire wear.

We've already touched ~all of the arable and non-arable land that's near to where people want to live. Forests clearcut, swamps (and deltas and the Netherlands) drained, rivers rerouted, reservoirs established, plains tilled, roads built, mountains conquered: We've been shaping and expanding the habitable Earth as it suits us for a very long time.
We're humans. We do that stuff.
And we're natural creatures like the rest of them are.
Here's a fun thought experiment for you. If you dug a 1 mile cubic square hole. How many humans could you fit into it? The answer is not only all of us but about around an order of magnitude more on top. I'm not sure if this emphasizes how few humans there are, or how massive the Earth is. But it's the same point in both cases.
Some human activities can have an outsized impact, but the overwhelming majority of those activities remain necessary regardless of where people live, and some will have an greater impact with widespread urbanity since some things like energy/food/water can be relatively cleanly decentralized in rural settings, at least partially, but require complete centralization in urban settings.
A very large fraction of land (~50%) is currently used to grow biomass to feed 8 billion humans. Nothing about that land is 'natural' - it's a carefully engineered environment that's quite hostile to animal life.
The land that people live on, whether it's in a city, a suburb, or in a rural manner is a rounding error compared to those demands.

Where's the food going to come from?
And the best way for Earth is we all migrate to Mars aboard Elon Musk's spaceship.
It would also be better for the earth if there were no cities and everyone went back to village farming and local communities. I also don't see that ever happening nor do I want to ive in a city.
That is my understanding too, but many people equate rural life with „natural“. Unfortunately the rural environment is all but natural. The cultural landscape that has been engineered over centuries all but displaced true wilderness and is largely devoid of biodiversity. The better we become at industrial agriculture, the worse the situation is.
