  • The way you’ve worded that suggested to me that there isn’t an actual solution so, for the people who didn’t click through, I’ll point out that the article concludes: “more sustainable alternatives to plastic bottles exist for all three types of beverage”.

    That said, in order to compare the environmental impact, there has to be some kind of weighting between the energy cost of manufacture and the direct environmental pollution (discarded plastic choking marine animals; microplastics; etc). I’m not sure it even makes sense to try to combine them. Climate change is an imminent existential threat, whereas microplastics are poisoning us but not obviously killing us.

    I also wonder what they assumed for the energy source in the glass manufacture. It is mostly fossil fuels at present, but the industry is moving towards electrification.












  • The top of this comment thread is a person claiming that men do all the hunting in every primitive society, not just hunting based on long distance running.

    You came into the thread to criticise a paper that showed that women hunt in 50 different societies around the world. Even your estimate of 50% is plenty enough examples to debunk the “all the hunting” claim.

    Women are perfectly capable of drawing a bow that is suitable to hunt monkeys, rabbits, squirrels, small birds, etc. Accuracy is more important than power.

    If your strategy for hunting mammoths involves your physical strength, you’re gonna have a bad time.


  • You would need to be in luck. Let’s assume that they studied all 200 uncontacted tribes. To bring the overall rate to 50%, you would need 119 out of the 200 to be exclusively males hunting - 60% of those societies. The researchers studied 63 societies and found that 20% of them were exclusively males hunting.

    But what’s the point anyway? The hypothesis is that males evolved to be bigger for hunting, even 50% of societies where women hunt is enough to make it implausible. In those societies, women are hunting in spite of their apparent size disadvantage.

    I think you should ask yourself whether size is actually important for hunting. We don’t wrestle our prey. Size doesn’t matter if you’re bringing down monkeys from the trees with a bow and arrow, and size doesn’t matter if you’re trying to bring down a mammoth.
