    i don’t understand it either, because there’s so little of it. and also, we know how to handle dangerous substances. like, asbestos stays dangerous forever.

      Oh, this is one i actually know. I wish I could find the exact YouTube video where I learned it, butnuclear waste disposal is a massive long-term problem.

      It boiled down to answering the question of - how do you prevent people from digging up all your buried nuclear waste for the tens of thousands of years it will continue to be radioactive? It was a super interesting watch, so I’ll see if I came find the vid after I get off work.

        yeah “no great deed is commemorated here” etc etc etc. spooky stuff.

        but… that’s also true for asbestos. except it’s worse because the moment you dig it gets worse, it can get into the water supply, and it doesn’t stop being dangerous. it’s carcinogenic forever. there are entire mining towns in canada that are condemned and cordoned off because of the risks of asbestos in the air.

        like, there are as of right now two countries that have long-term storage plans for nuclear waste, and they both are “dig a big hole”. …okay? so just do that. there are thousands of abandoned mines that go down almost a kilometer where we have extracted millions, billions of tons of material. the total amount of nuclear waste ever produced is like… 200 000 tons. and uranium is dense, so by volume it’s not a lot. just fucking dump it in an old mine if you want.

        or better yet… don’t! the fact that it is still radioactive means that it is still useful for generation. with the technology we have today, we can breed away like 40% into inert substances and new fuel. if we dump it all down a hole, what will happen is we’ll have to dig it back up again in 20 years because it’s too valuable to leave down there.

        i used to live next to the biggest iron mine in the world, the luossavaara-kirunavaara mine. they have mountains of slag and waste product. far bigger than the actual mountain the mine is in. and in the mid-2000’s, they started mining the slag. because there’s still so much useful material in there.

        That was always so frustrating and annoying to me. “We won’t invest money on nuclear power because someone in 10,000 years might get radiation poisoning from the waste we will carefully bury underground. So, let’s keep burning coal, pump the waste smoke into the air that will kill the atmosphere whitin three decades and give everyone radioactive poisoning, today!”

        Humanity was handed the key to stop global warming dead in its tracks and skip straight to renewables with a healthy planet. But we can’t seem to resist the temptation of blowing people up for a slightly higher profit next quarter.
