      @@Northern85Star An impossible solution is not an solution, people ranting about reducing population are mostly people who do not want to change anything. They are the people who just want to keep their lifestyle, and blame others.
      We need to change the system, aka get rid of capitalism. Replace profit incentive with healthier and more sane values. Currently we are basically trying to desperately control capitalism, and it simply does not work. Regulating it leads to just things like large automobile manufacturers scamming the system by faking emission test, as its more profitable than following them.
      Trying to run the whole world by relying on greed is insane. It has always been insane, and it has failed again and again. We need common ownership, not private profits. We need real socialism.

      nobody nowhere Getting rid of capitalism is completely unrealistic, much more so than a pandemic. No one is willing to decrease their livingstandard. Even if it was possible, it would not be a solution. Earth cannot handle 51 people per square kilometer land (which includes unihabitable land like mountains, gletchers etc). If all people on Earth were to become self-sufficient, we would hunt all edible animals and plants to extinction - or try to, while people die of starvation and murder due to local shortage of food. Nothing is a solution with this massive overpopulation, bar drastic population decline.
      Do i want to experience the period in which this decline happens? Not at all. But it is the only solution.
      What will happen is this: we will shift our ways of consumption, until everything on Earth is an artifical, human controlled environment. Biodiversity will decrease more than anytime in Earths history, but we will make artificial duplicates with all their side effects. And so on and so forth.
      The only good thing about this, is that it will prepare us for artificial environments necessary for space travel and colonisation of other planets.

    • @Northern85Star

      nobody nowhere Note: you are trying to combat effeciency. This is why you cannot get rid of capitalism, it is the most effecient system to increase the living standard of people, to accumulate wealth etc. Humans have been obsessed with this since the beginning of mankind, it is one of our most fundamental instincts due to our social nature. Ownership, power. You do something for me, i give you something in return - if done large scale, it equals power - whether it happens directly or indirectly. It is why we pay tax, so that the elite become powerful through wealth. Even other mammals display this behaviour on a primitive level, but ofcoursee, without material to distribute, it only works directly.
      Technology and its industry will not help, as it simply shifts ways of consumption, while manufacturing will on its own be devastating to continually accomodate Earths massive human population with new technologies ment to shift ways of consuming.
      It is depressing, but humans do not understand the complexity of nature well enough to not destroy it - even with our best intends. That is why we must become fewer.
      Btw: i am a minimalist, and plan to become semi self sufficient as i move to a remote area. Not for climate reasons, as it is not a solution while Earths population is as big as it is (and i hope not too many people get the same idea) but for reasons of personal freedom.

    I like this guy do not believe that the challenges of our time are too big for us to handle. There are little things we as consumers can do to help our environment. I have made it a point to drive less. We planted a garden in the backyard of our suburban home. We have a compost. We recycle everything we can. We use reusable grocery bags, when we remember them. In a few months we are moving because of my wife's work and with the move we decided we don't need as much living space as we currently use. We originally tried the Meatless Mondays but that turned into less meat Mondays. Now we are committed to reducing our meat portions and so far I am good with it. Our new home is in a condo community and I am hoping to start a community garden there and spruce up the area with a lot of flowers and a new tree every year. I think it would be great to have a community Christmas tree we could decorate as a community. We could make an event out of it with hot chocolate and cholaring.

    • @reichrunner1
      @reichrunner1 5 років тому +1

      @Waxoff Waxon Right, and they in turn produce nitrogenous waste. I guess they sequester small amounts of it in their own proteins, but it's really odd to claim that they are pulling nitrogen out of the water column. And any that they do consume is already organic matter. It's not as if they are cleaning water of fertilizer runoff like this video was implying

    • @tentimes4
      @tentimes4 5 років тому +2

      to both individuals.... mussels are filter feeders. They consume mostly algae. For the mussel to grow in size, it must produce amino acids in the form of proteins. The principal component of amino acids is nitrogen. Since the mussel is such a fast growing shell fish, the mussel removes approximately 10 to 20 times more nitrogen than it produces from wastes. Mussel don't sequester small amounts of nitrogen. Mussel sequester proportionately huge amounts of nitrogen compared to the rest of their body mass over the period of time it took to grow.

    • @reichrunner1
      @reichrunner1 5 років тому

      @@tentimes4 Yes mussels (and all living things) need amino acids, and by extension nitrogen, to grow, they are not able to directly use ammonia for this purpose. Sure much of their food source uses ammonia, but that ammonia would be sequestered with or without the mussel. It's the algae doing the sequestering, not the mussel.
      As for your claim that mussels remove 10-20 times what they excrete, I find this extremely hard to believe... An animal generally needs far more energy to grow than it needs physical protein, so the idea that mussels grow 10-20 times faster than they respirate seems rather far fetched. If you have something to back that up, I'd happily read it. Just seems a bit extreme to me

Look up the work of Chris Hedges for example. Or John Perkins. Learn the history of the labor movement and it’s literally all about fighting against the coercion of business. And it’s filled with the dead bodies of men and women who stood up to corporate exploitation.
