  • Humans existed for well over 200,000 years without government. There is strong evidence of massive settlements that existed for extended periods without any sign of being ruled, just people living and cooperating.

    In fact, it’s the formation of governments that could enforce exploitative economic systems that started the ecological collapse of this planet in the first place. Humans without government live in balance with the rest of the world.

    The idea that humans, to survive and thrive, require the formation of an entity (government/state) that allows the subset of the population in control of the it to exploit the subset not in control of it is a dangerous fallacy.






  • I not sure this is true.

    As I understand, humans have an extremely acidic stomach compared to other animals, even carnivores. Our stomach acid is on the level of scavengers, and this is to kill bacteria and parasites in the food we eat. Humans could be more tolerant of spoiled food than most other species.

    The modern western diet/lifestyle can damage our digestive tract in ways that affect our pH and microbiome making us susceptible to what we should normally be tolerant of. Anyone taking antacids or dealing with heartburn type issues I would expect to more vulnerable to food poisoning since any pathogens can more easily pass deeper into their digestive tract.

    The short digestive tract in a dog is all that is needed to extract nutrients from animal sources, digesting plants requires help from a microbiome and they need somewhere to live and do their work, this is why plant eaters have extensive digestive tracts that are not very acidic so they don’t kill them off. Humans (not sure about other animals) neutralize the “chime” exiting your stomach so that it’s pH is appropriate for the microbiome living in the intestines.

    The human digestive tract suggest sit evolved for adaptability, a healthy human can safely eat anything from carrion (not saying it’s fine, just that we evolved to be able to survive it), be a vegetarian, or eat mostly meat and thrive.

    Huh, tldr might be a bit hard but I’ll summarize-ish.

    Everything radiates heat, you do, the air, the floor does, etc, you can see w/ infrared camera. Most of that energy is radiated in a wide frequency band (it’s all over the place), absorbed by your surroundings and re-radiated and energy just kinda bounces around. If you paint your roof white, you don’t absorb extra heat from the color and can reflect light into the air, but then the air gets hotter so it helps a bit we all know white reflects and black absorbs.

    Well, there’s a small band of electromagnetic frequencies that the atmosphere is virtually transparent to. In the last decade or so scientist have invented special metamaterials, which instead of radiating their heat in a wide band, radiates most of it in a narrow band, the band that can pass through the atmosphere. This means that it beams infrared energy out into space at a far higher level than anything else.

    Because the heat is radiated into space passing through the atmosphere, these materials can actually cool themselves significantly below ambient temperature. Utilized properly, this cooling can be used to cool buildings and many other things without consuming energy at all.

    This particular video, this guy is able to accomplish this without exotic or dangerous materials so you can DIY (since these materials are not even for sale yet).



  • I hear this every single election.

    1. Because as we move into the future with a larger population and worse environmental destruction, the stakes become greater.

    2. Because we’ve been on the verge of losing our democracy for a couple decades now. I’m almost 50, we’ve been on the verge since the presidency was taken from Al Gore. It was not this way before that in my lifetime.

    You think one election is going to take a nation on the brink to being in safe harbors? This is a battle for democracy that occurs over multiple elections, why is that so hard to understand? You can only repeat what your friends say?
