Living in a hut in the woods is quite different from living in pre-industrial society.

I do wonder whether the Amish would take converts. There are certainly communes around that would. And yet, here we all are.

Granted, here we'd still be if half the population was voluntarily leaving modern society.

Nevertheless, you are still free to do it. Maybe join the Amish, for starters (although afaik they don't shun all technology).

In any case, you can get together with a group of friends and live the way you imagine. There are enough people who dream of that kind of lifestyle, that you should be able to find a group that is large enough.

It's not so easy for the individual to do that. The skills necessary for pre-modern life are only taught by being raised by a group who lives that life. Nearly all such groups have been destroyed -- and even if you wanted to, you couldn't go join a tribe at the edge of civilization as an individual.

Not to mention that in many areas, it's not possible to make life by hunting and gathering because biodiversity in the natural environment has been destroyed. So, it's not really possible as you say.

Even though it's not really possible, such bullshit is worth giving a bit of thought, at least.

You can use the internet for two more years to learn, THEN go into the wilderness. I would even allow you to take some tools from industrialization, maybe a knife made from steel and proper clothing and a tent. Fair?

As for suitable areas, there are still undiscovered tribes living in the Amazonas. I think you may still be able to find some places where you can live your dream.

If you think longer term, what's the point of having a higher quality of life if we die because of pollution and irreversible climate change anyway?

We won't die because of that - pollution has gone down anyway, whether climate change will really become catastrophic has yet to be seen.

But even if you believe it will - what's the point to anything? In the end everybody dies, no matter what you do.
