    After seeing the news piece on guys using two cars to steal a haybail I think in australia it makes me realize just how much worse this is than the depression. I mean people would steal food, heck even eggs, and maybe even live chickens. But straw?! Things are sooooo trumped.

        The list of nouns and verbs he has attached his name to grows with me. initially I think it was just fuck but now it fuck, ass, and shit and im thinking of adding cunt. Maybe shit was first. So hard to remember.

      If you think it’s bad now, just wait untill climate change gets worse. We’re going to live through some serious shit. Like awful times for thousands of years if we can’t get it under control.

        For what it’s worth, a lot of synthetic biologists are looking into Carbon Concentrating Mechanisms (e.g. carboxysomes) so that we can improve carbon capture in native plants. Honestly, as a protein engineer / synthetic biologist myself there’s even odds I could end up working on it too; though, it’s not my first choice.

          I feel like we need to start building giant hypertufa obelisks to grow moss on. Maybe labyrinthine windtunnels and stuff like that. Stuff that’ll make future archaeologists go “whoa,” but mostly just replace oxygen in the atmosphere while absorbing carbon dioxide…

        I’ve looked at some tentative projections, and it’s downright apocalyptic.

        At our current “business as usual” path, we should be expecting wholesale collapse of countries by 2035 or shortly thereafter, with +4℃ temps causing agriculture destruction that leads to a 60-80% drop in human populations by 2050.

        And when people are desperate to live another day, they will absolutely tear apart any infrastructure they can get their hands on in order to survive. We’re talking about reverting to the Iron Age or even the Stone Age.

        And when almost 100% of all resources required for building or even maintaining high tech civ are no longer accessible without high tech civ… there is no coming back from this collapse.

        yeah and I kinda new this all along since the late aughts at least but still its hard to live through. the desperation of the ones at the top is more than I could fanthom to.

    Sand of various types are running out around the world, and it can be quite the expensive challenge to get the right type for your particular project, many times involving trying to preserve land from water erosion.

    Maybe industry is working to create artificial sand grades for current and future projects, I’m not sure…

      Thats pretty shocking to my untrained ass. I always assumed they did mass-produced sand, grinding up their own stones and stuff.

        River sand is the right amount of jaggedness to where it can pour and settle into the right density in cement to have the right strength in the finished concrete. Ocean/beach sand works, too, but needs to be rinsed with fresh water, and is usually pretty valuable where it is (for beach resorts and what not).

        They’re testing for how to use different types of sand (desert sand, manufactured sand, recycled sand) and testing the pouring characteristics and resulting concrete strength, so that they can make reasonable decisions on when it’s worth using substitutes.

          Civil engineering really is just the study of concrete isn’t it

          No shade, just amazed I’m always nearing more about concrete lol

            Yeah, one of the issues I’ve read about happening for concrete failures was that some construction crews are under enormous pressure to salvage concrete that had been mixed too early, or delayed in pouring, or whatever, and where the concrete pouring characteristics cause issues (or crews add unauthorized water or things to slow down curing and then alter the characteristics of the poured concrete without the engineers’ awareness).

            It’s wildly counterintuitive to those of us who don’t work in the space.
