While hunter-gathering is no Garden of Eden, I don't think it's as bad as you describe for the simple fact that evolution has molded us to it specifically. Earth isn't designed for human life, but human life most certainly is designed for Earth.

No, I dont think so. Would you say that to all the extinct species? There's nothing guaranteeing you don't starve. There is no design. Genes are just "random reproductive bets" with fairly high probabilities of failure over the long-run. The environment is basically guaranteed to change faster than your species can evolve, including via meteor. I dont think the rabbits who die alive eaten by foxes, and the foxes which starve from eating all the rabbits regard that cycle as "designed for them". Nor likewise, were the dinosaurs that impressed by the sky going dark. This idea that "we had a home" or "there was once Eden" in any respect is wrong. The life which we were evolved for is one in which if you survived 10, then you might not survive the lion, and if you survive that, not the volcano, and so on. Your body is just a bet made over millions of years, and not one any conservative gambler would take.

  Extinct species become extinct because there is some change in their environment to which they are not successful at adapting. Generally speaking, neither the human genome or the wilderness of Earth has changed since we built our first huts. You're correct in your regard for exceedingly high child mortality, though it bears no weight on the survival of humanity as a whole in a technology-breaking event. The human body is indeed a bet, and one that has paid off for ~300,000 years and about 12,000 generations, if we start counting from Homo Sapiens. I'd very much take that bet any day.

    There's not that much wilderness left. Globally, The max distance to a road is something like 250km, in the middle of the Sahara. In the lower US, it's more like 40 miles. Entire ecosystems are gone (e.g. tallgrass prairie), or are only present in chunks that are only a few square miles. There are basically no old growth landscapes in Ireland/England. All the old trees were harvested, and sheep were farmed in the high places. Biomass of land mammals is heavily skewed to Humans and their livestock.

      It will revert very quickly. In two hundred years (outside of the dead cities and major highways), you'll have to look hard to find traces of the old civilization.

        It may revert -- some -- but without the previous genetic diversity because what's gone is gone. Apex predators are mostly gone over large parts of their former range. The species of trees in the forests that we had in UK/Ireland just aren't there any more. It will probably be taken over by hedge laurels. Deer have been introduced where they used to not be. Florida is going to be a hellscape of escaped pets, like the pythons. The old growth forests of the PNW aren't going to come back for 1000 years or more, if they even can at all due to the extinction of some species and the addition of invasives.

    The earth has been here 4bn years... a species profliferating for over 300,000 years isn't even "making its money back". Almost all of past human history has been spent dealing with mass death, and it isnt clear almost that won't be the case for future history, until we're extinct. The world isnt made for us, and there's no reason to suppose we won't go faster than the dinos

Hunter gather doesn't work so well in a paved city of a million. The Amish would likely be fine. Farmers with land and skill would likely survive, but would be able to provide crops for large numbers of people. People in cities would die.
- mach1ne 4y ago
  I wouldn't hedge by bets on the Amish either though. The starving majority can be nasty, and permanent positions difficult to defend. Most people anywhere would starve, but intelligence has a cockroach-like ability to survive in the crevasses.

  Cannibals could actually thrive, at least for a while, I think...

Most of us have little idea how to go about hunting and gathering. And if we tried, we'd soon find out that there are far too many of us to subsist on what can be hunted and gathered around us. Soon enough, we'd be at each other's throats.
- mach1ne 4y ago
  It is very true that the Earth can simply not support 7-8 billion people without machine-based agriculture. The population would quickly collapse to a level which hunter-gathering can support, likely overshooting by some amount due to initial adjustment.

> While hunter-gathering is no Garden of Eden... Without electricity, we would be back to 200 years ago. That's still like 10,000 years after most humans were hunter-gathering. Did we forget that for most of civilization's time, we had technology to help us do stuff, just not electricity-based technology? For example vapor engines would work just fine without electricity. Agriculture would require a lot (really a lot) more people, but would still be possible with manpower and animalpowered machines, like it was for thousands of years. Also, it's not like our knowledge of electricity would just disappear... we would just have to repair and make new machines, which may take a while but most people would probably survive that.

  It would be more like 1200 years ago. Because almost no one today has the tools, skills, experience, and supply chains needed to recreate the Industrial Revolution. It's one thing to know that a steam engine is possible. It's another to build steam engines at scale when you're starting from iron ore or perhaps recycled scrap metal, and the most sophisticated available practical skill - and exceptionally rare at that - is blacksmithing.

And even if we did, there is no easily-accessible source of energy anymore. All the accessible coal and oil have already be exhausted. We're now digging under thousands of meters of sea water and seabed to get to the sources of energy that are left.
