• The death of all the coral in Florida.

    It was front-page news where I live a few days ago but not a blip of it could be seen anywhere else.

    It’s easily the most important news of the past two months and will negatively affect life on the planet anywhere but fuck all if humans outside of a local area could bring themselves to give a shit.

        Okay, in some ways bio char itself is like the regular charcoal we know from BBQs and the manufacturing process can be quite similar. But like most things, it’s a very complex topic, therefore, I’ll only give a very rough overview for now but I’ll also share some links to further information 👍 • While charcoal is mostly made from valuable wood, bio char can be made from every form of biomass, meaning it can be made from every form of biomass waste.
        • During the manufacturing process, the chemical carbon in the biomass is put into a form that is stable for several thousand years, so unless the bio char is burned again it can’t reenter the atmosphere. • Each ton of bio char produced using plant based waste is equivalent to 2.6 tons of atmospheric carbon dioxide captured by those plants. • The manufacturing process generates a small amount of base-load energy which can be, depending on the size of the facility, enough for several hundreds of households. • The end product can be used to revitalize the extremely degraded soils we’re fighting in industrial agriculture right now.

        Tl:dr we (indirectly) take something very bad from the atmosphere, generate useful energy with it and then store it within our dead soils to revitalize it.

        It is not THE solution but I think it’s a feasible improvement.

        I’m happy to answer more questions… here are some links ✌️

  • Baltimore schools are some of the most publicaly-funded in America. And yet, in 23 schools, 0 students passed a math proficiency test. ZERO. There were 10 high schools, 8 elementary schools, three middle/high schools, and 2 elementary/middle schools.

    The news broke when a father raised the alarm. His daughter graduated high school with honors and was accepted in a military college. When she started classes, it became very apparent that she was not anywhere near ready to begin those classes and was put on academic leave. Turns out, instead of funding programs to get students up to speed, these schools just kept lowering standards for graduation, so that more students could pass, inflating graduation numbers.
