    Biologist here, the body itself isn’t what grows the “greener grass”. It’s just the start of a long biological process that will lead to ecological growth.

    A tree isn’t going to feed directly off of the body. But the decay process will provide nutrients to the tree. We’re talking about insects and fungus at various levels of the process here. You can look up things like the Trophic Levels and Nutrient Cycles for more details on this whole process.

    TLDR would be that the corpse floods the area with nutrients and maybe even kills off the plants with over abundance of nitrogen, but then fungus and bugs move in, then bigger bugs and small animals, and so on and then better plant systems. It’s kind of neat.






  • I’ve been saying this for years. Use nice textured recycled plastic. The amount of cool textured and nice feeling materials out there is insane.

    Gimme a plastic screen too. If someone is concerned about scratches they can add a glass protector. Those people already do anyway. There are even plastics that could be used that would resist scratches incredibly well.

    Then my whole phone is flexible and nearly unbreakable.


  • Usually what happens is whoever needs to know has their own specific way of determining the thing.

    As a wildlife biologist, the meme description is pretty good and would suffice for just about anything I need. The present or recent past circumstances are the most important to my work.

    If I were interested in the geology, or say ground water, earth studiesor, or even the more distant past then this definition you share becomes more useful.

    There are going to be even more criteria that apply for different groups, and even sometimes none of these definitions we’ve seen would matter because you only care if it sustains a specific species or something even less obvious.


  • I don’t specialize in that particular area so I couldn’t say honestly.

    My primary focus when I did was just dealing with the Everglades and surroundings for the most part.

    Worldwide I’m not sure I could even guess what should be more common.

    Canada has those prairie potholes which are usually marshes and Canada is huge, so maybe sheer numbers it could be something like that, but by size you get things like the Everglades. I’m sure someone knows though, just not me.

    Wildlife biologist here, and I have to concur with just about all of this.

    I think we generally look at a viruses and consider them alive but just barely. While prions are not because they (proteins) are what is considered one of the building blocks for life. Self replication being one of the major criteria we’d look for. We look at a very macro level of life but our education and work has a strong overlap down here a well.

    This is such a well written post! Gets the point id like to make across in a much better way than I could







  • More teachers per student.

    Starting at about 4 student per teacher, and each year or developmental step gets a few more students. If still doing grades/years then another 2 or 3 students per. This let’s each teacher learn about each student and actually catch any development hurdles early and give the children direct attention. As children grow they get to learn to socialize more and more in bigger groups.

    Gamification and goal adjustment

    They shouldn’t have letter grades anymore, or if they do they aren’t locked at percentages. That means the grade can only go down as they make mistakes. Instead they start at the bottom and have to answer so many questions correctly to prove understanding. They also don’t run out of questions. When they get something wrong an explanation is given as to why and even steps on how to understand and work through it. When they understand a topic they move on and more questions on the things they struggle with are given. All of this is underpinned with game things like achievements, and unlocks, and rewards and so on.

    Focus on practicality, strengths, and real world mentorship

    After learning the fundamentals, more education should focus on their strengths, wants, and practical application. Actually doing the things is so important so getting out there and witnessing it, doing it in person is important. So there should be mentors like olden times. Students get to shadow people long term, actually do what they do, learn with them, earn with them. Multiple opportunities should be given that students find what they do enjoy, what they do excel at even if those things are different. This gives the student early indicators and choices. No longer needing to determine what they wanna be when they grow up without any real world experience.

    No standardized testing, overhaul of how each subject is taught

    Maths is amazing. Glorious puzzles to be solved. It’s currently taught in the worst way imaginable and sucks all the fun out of the subject. Now the majority of people hate maths. This is the same for quite a few subjects. A lot of that is due to standardized testing or how it’s taught. Those tests should disappear. Testing, just like grading above, would be catered to the student. Students still need to achieve reasonable real world goals, but timed stadardized testing in a high stress environment isn’t the way. Students would be afforded all the tools they would have access to in the real world. They would be taught how to use those tools effectively instead of told to memorize. They would be afforded a chance to enjoy they education and proof their worth in the way that works for everyone including themselves and not just to a random committee that made up an arbitrary system ages ago.

    There is more but I’ll stop here.
