  1. Re:Food Supply on 'The World Might Actually Run Out of People' (wired.com) · · Score: 1

    That's somewhat pedantic... When I said animals "maintain" their population, I didn't mean to imply that it was somehow voluntary. I guess I should have said "Animals maximum population is determined by the available food supply."

    If you read the very next sentence in my comment you would have noticed that I said exactly that. We waste half the food that is produced.

    That's an interesting point about Kodiak bears, though I suspect that since they've been doing that for a LONG time, they are participating in a (relatively) short-cycle "food web", and that the bits of fish they they don't eat are quickly taken care of by other organisms, and since their population is relatively stable, they're not going to overfish like humans have done.

    A lot of human food-waste is not reintroduced to the biosphere in a short-cycle process, but putrefies in landfills along with tons of toxic crap. I'm sure there are some happy micro-organisms in there, but isolated pockets of rotting crap doesn't do much for the ecosystem as a whole.

    If most food waste was composted and used to feed the soil, it would be a useful resource, rather than an energy sink, and there has been some progress on that front.

    Voluntary limiting of reproduction is odd and fascinating indeed, and will be our saving grace if universally adopted, as the models predict.

    My point, which I guess I didn't really state, was that a much smaller population of humans would probably be an asset rather than a liability in the grand scheme of things, and it's hard to imagine a scenario where humans "accidentally" go extinct because they don't want to reproduce!

    You're correct, in that I was only referring to food production. You're also right that our "Modern" "post-industrial" society is not only unsustainable, taken as a whole, it's self-destructive and self-defeating.

    However, food production techniques have not remained static. We're not going to be stuck in late 20th-cenutry production-mode forever, in fact we can't be. You may or may not be aware, but there has been a *HUGE* shift in food production over the last decade or so, away from giant-agribusiness-controlled methods and practices to (more) sustainable practices. Here's a statistic I recently heard at an organic farming conference:

    70% of the current world food supply is now produced by small and medium sized farms. This is a 180 from just 20 years ago.

    That 70% slice of production uses only 30% of the total energy input into creating food.

    The remaining 30% (mostly agribusiness-produced factory food) uses 70% of all energy inputs for food production.

    Think about that for a minute.

    That's the trend. It's not happening (primarily) due to activisim and smarter consumer choice (though it's that in part) but because the way we had been been producing food was not just unsustainable, but STUPID! Giant energy-inefficient petrochemical farming practices are TOO EXPENSIVE in every sense. They deplete the soil, they produce less-healthy food, use chemical feedstocks that would be better suited to other purposes. The list goes on. These hugely wasteful practices are fading from use, simply because the alternative (small and mid-scale more-or-less "organic" farming) is BETTER IN EVERY WAY -- it's still not "sustainable" in every sense, but we've made HUGE progress in a short time-frame. There is a sea-change to REGENERATIVE agriculture underway, where instead of depleting topsoil, farming (with good stewardship) is beginning to actually create fertile topsoil, as natural grassland and forest do. Use of cover cropping, no-till, mycorrhizal and nutritive soil amendments (rather than "fertilizer"), companion planting, smart rotation, and many other practices, taken from antiquity and based on current science are turning the tide.

    As I said, there are a lot of BIG IFs and we have many challenges ahead of us, but the trend, at least in the area of food production is looking up.

  4. Food Supply on 'The World Might Actually Run Out of People' (wired.com) · · Score: 1

    Animals generally maintain their population to a level that consumes the available food supply.

    Current food-production levels can support roughly 12 billion humans (We waste about half of the food that is currently produced. We're definitely different from other animals in this respect)

    While it's true that most late-stage industrial societies are currently running birth rates that are below replacement level, and that the most likely "peak-population" scenario is probably 9-14 billion people, sometime around 2050. Speculation as to what happens after that is exactly that: speculation.

    That said, any population level that is below max possible food production level should be sustainable nearly indefinitely, be it 14 billion or 14 million, we'll do just fine, provided we make it through the peak transition without any sharp dropoff: war, famine, disease or severe global environmental catastrophe. If the transition is reasonably smooth (which I agree is a big IF with things as they are).

    Humans are incredibly adaptable, and provided we use our technology well (which again is a pretty big IF given our track record). I don't see any problem maintaining an advanced technological society with population levels at pre-industrial levels. The headline and article would seem to be pure sensationalism.

  5. Most plants also (quite literally) feed the soil microbiome by producing sugars and other nutrients that bacteria and fungi absorb. The microorganisms return the favor by fixing nitrogen, for plants that don't do that themselves, as well as defending the roots from non-friendly microorganisms, and probably a whole host of other things that we don't even know about yet: perhaps even participating in the communication network that plants use to help identify clones vs. same-species neighbors vs. other plants.

  7. Not quite... since the water and valves could (I think) only find a "local minimum" or naive solution, not a near-optimal (global minimum) one, like the amoeba does. The lighted areas on the chip don't *prevent* the ameoba from going there, and in fact to find an approximate global minimum solution, the ameoba *has* to sometimes go where it doesn't want to, in order to maximize it's nutrient intake. In other words the water can't "decide" to go through a closed valve, but the ameoba can choose to extend into a lit cell, in order to maximize survival advantage.

  8. Yeah, that was my first though too, since the summary makes it sound that way, but the article explains in depth:

    The challenge for the plasmodium to find the shortest tour is that its branches should not enter the frequently illuminated lanes and should elongate into the optimal combination of the least frequently illuminated lanes. However, the optimal combination cannot be found as long as the branches always obey the control principle; if always the branches shrank when illuminated and expanded when not illuminated, the plasmodium would not avoid falling into a local minimum. To better explore the potential energy landscape and locate the global minimum (the shortest tour), the plasmodium needs to misallocate the resource to its branches and the branches must violate the control principle with a certain small probability, because the lengths of the tours can be compared only when the branches operate contrary to their photoavoidance response

    so the computer is only really defining where the "bounds" of the problem are. The ameoba really is doing the computational work (going *against* the computer's control) to find a nearly-optimal solution.

Migrating to PHP7 is really not that bad by comparison, and PHP7 fixes most of the really bad warts in the language.

    That's only partly true. The last "red tide" of this scale happened from 2004 to 2006. However, the number of dead animals on the beaches seems to be unprecedented this time, probably because the "red tide" is accompanied by a blue-green algae bloom, which is caused by a different organism, although has the same proximate cause: too much for the algae/bacteria to eat. The governor has declared a state of emergency, so even he's taking it seriously (now). Probably at least partly because of the potential billions in lost tourism dollars, though that's really closing the barn door after the horses are out.

    The link to agricultural runoff is not something that is being made up by hippy-dippy environmentalists. It's a very real, well-documented phenomenon, and has happened virtually everywhere that large-scale agricultural pollution is allowed to run unhindered into the sea.

    I spent a lot of time as a kid (in the 70s & 80s) in Lee county, and "red tide" during that period usually just meant that you couldn't (safely) eat the local seafood, not that it was washing up dead on the beach.

    Having said all that, Florida (at least where the people are) is one of the most heavily-modified environments in the world. There would be hardly any buildable land through most of coastal Florida if it were not for the ubiquitous drainage ditches, tunnels, canals and other ground works to keep the water out of buildings and off of roads.

    They *claimed* that their ultimate goal was "socialism for just us aryans, and no one else, once we get rid of all these sub-human dregs that aren't 'True Germans'" but that was probably never going to happen, even if they conquered Europe. Nazis were fascist, not socialist. The actual distinctions can get fuzzy, and this stuff is not ever cut and dry, and the political spectrum itself has warped over many decades, but to say that the Nazis were "left-wing" in any meaningful sense is disingenuous, at best -- neither were they mainstream "right-wing" either, but if you put Fascism and Nazism into the language of the 19th century, they would have indeed been called "far right": Totalitarian, xenophobic and nationalistic.

    To make matters more complex, within the party there were "conservatives" that wanted to hang with mainstream reactionaries and other capitalists, and "radicals" that saw capitalism as a "Jewish threat" (hey, their words, not mine). So the party was basically schizophrenic (surprise surprise). At it's inception the party made all kinds of social promises to the proletariat, but none of that ever materialized (they lost the war after all), and with a few exceptions (those corporations that weren't nazi enough), Hitler let private capital thrive quite nicely.

    To say that the mainstream left in Nazi Germany was anti-Semitic is also disingenuous, since *virtually everyone* in Germany at the time was to some degree, regardless of where they fell on the political spectrum. If anything, it was the left and the far-left that led the fight (such of it that there was) against antisemitism in pre-war and wartime Germany.

It's that the various players have never had an incentive to share/pool or at least wholesale resources to each other.

I sometimes even end up places where I have *signal* but the tower tells me (essentially) that while I can talk to you, I won't let you use me, since your provider doesn't have a billing arrangement with me in this area. I realize these things are complicated, and I'm perhaps oversimplifying, but they've been made more complicated than they need to be.
