    Hi there, gen Z person here. Things are bad but remember that, as always, you only see and hear about the vocal minority. No matter how poor American education standards are, it is irrefutable that Trumpism could not exist without idiots from all generations. The education paradigms we are emerging from cannot possibly be worse than those which produced tens of millions of conservatives and hundreds of millions of nonvoters. This is specifically because of those gen X leftists and millennial teachers you mentioned. We aren’t competing as generations–failures of the past become the lessons of the present because older generations also have smart people. So how do you know gen Z won’t do even better? Everything else aside, growing up under fascism creates widespread discontent. I’d say from personal knowledge that for every one gen Z kid that believes in the system are five who at least recognize it’s broken.

    Now, I won’t pretend to be particularly optimistic either; things are bad. However, I also want to believe that we can and will do better. And maybe I’ll be wrong, but at least I haven’t given up hope.

    decomposers turn organic material from corpses into simpler nutrients like nitrogen, phosphorus, and potassium. for example, proteins are broken down into amino acids, which then decompose into ammonium and nitrates. these nutrients are absorbed into soil and consumed by plants

    tldr: plants eat corpses after decomposers turn them into nutrients

    not op but i think your skepticism is justified

    this seems to be where the image originally came from. the author explains the challenges with making speculations about historical populations in that post. the demographers, toshiko kaneda and carl haub, estimated 117 billion people have lived over the last 200,000 years. here’s the explanation given on the original post:

    The majority of them lived very short lives: about one in two children died in the past. When conditions are so very poor and children die so quickly then the birth rate has to be extremely high to keep humanity alive; Kaneda and Haub assume a birth rate of 80 births per 1000 people per year for most of humanity’s history (up to the year 1 CE). That is a rate of births that is about 8-times higher than in a typical high-income country and more than twice as high as in the poorest countries today (see the map). The past was a very different place.

    i think this is fairly reasonable, but original source is necessary. i think this is a more original source, and kaneda and haub are listed as the authors. their methodology seems to rely a lot on guessing, which makes sense. the 117 billion is probably not entirely accurate, but i’d say it’s a good attempt at estimating given what we know. there might be a more detailed paper somewhere but i didn’t really look too hard

    edit: also lot of hostility from other people here… lemmy gone downhill. i think there’s nothing wrong with being skeptical of data or science, even if it’s coming from qualified experts. unless there’s a detailed paper that explains EVERY step of their process, you can’t be entirely sure where their numbers are coming from. that said, i agree with those other guys that there’s not a lot of room to be skeptical in this particular case, since the authors explicitly say it’s a rough estimate. based on what we know, it’s as accurate as we can get. but still, nothing wrong with asking for sources!
