Ya, but the idea it was too late 100 years ago is idiotic.

Unless you decide capitalism was inevitable once implemented once, gradual correction was very much possible back when we figured out climate change required it.

We've engaged in insane overconsumption for a century, decrease in yields while we figured out the new process wouldn't have really been the huge deal people make it out to be.

It's a bigger deal now that we have the population we do and dwindling energy reserves and we're so far into overshooting any sane carbon goals. Because even just beating peoples assets with sticks in NA until they stoped driving 4 times a day and insisting on needing little mansions in the 'burbs would be a huge endeavour.

But people massively underestimate how much of our emissions are totally avoidable, particularly if you look back. No one really needs to eat meat, no one needs a backyard 2% of people ever even use, no one needs a couple hundred pieces of plastic shit or disposable outfits replaced constantly.

The majority of the world's emissions have been stupid indulgences like that, either at the point of indulgence or as they where being produced and transported.

Even now, life's going to get so much worse, but if you scaled back overconsumption in painful ways and quickly moved to, say, cut all corn production for fuels in the US and moved to install enough solar to allow a legislated shutdown of all carbon power sources you'd have a masive impact on the world's tragectory, and would make surviving in the states as it happens completely different.

Ecological devastation for a lot of the population and biosphere are locked in, but humans surviving is still a pretty trivial problem for the scale of our abilities at this point. The problem is still just that even in the face of this pain we refuse to say no to selfish idiots that want to fly to Mexico or whatever instead of rebuilding the electrical grid and building out electrical rail at speed to ensure basic infrastructural needs are met as our resource and energy budget collapses.

Also, the food production thing is kind of a huge canard. Climate change is going to make it brutal soonish, but at the moment the crops that can replace meats, which improve soil quality, are easy to grow. We just grow them to feed to livestock, despite them having like a dozen other fantastic knock on effects from being less perishable, and so requiring less haste and energy to transport and store safely, to being genuinely better for human health, from what we can tell.

People wildly overestimate how much of our being fucked was and is locked in, instead of just allowing dipshits to insist the sun shines out of their ass because they take "risks" under capitalism to insists that exposing them to risks is tantamount to genocide and so we all must die so that business logic allows them to stay rich.

Literally, most of why our species is fucked not for physics reasons but because we've already invested in bad infrastructure that uses polluting means, and we treat predictable returns as more sacrosanct than human life. I can't express many of the solutions to this problem under Reddits rules, but it can't be overstated how artificial and easy this is to solve. You can in fact tell rich trash they now own nothing but the personal property they use at home and just write off a ton of bad investments as a society.

Pain and suffering is locked in, particularly for the innocent species we've fucked over and the lowest emissions humans. Survival is still pretty trivial, contingent on us just actually trying to survive though, tbh.
