      This is where I can share what I learned in my ecology classes! There’s a concept called the ecological pyramid. The base comprises the primary producers, that is, plants which produce biomass with solar energy through photosynthesis. The next trophic level is the primary consumers, that is, herbivores that eat plant biomass. It’s a pyramid shape because the rule of thumb is that only about 10% of the original solar energy makes it up to the next trophic level.

      Guinea pigs are primary consumers. Tigers are secondary or tertiary consumers, eating animals which eat plants, or even animals which eat other organisms which eat plants. Only about 1% of the original solar energy in the plants eaten by the animals the tigers ate goes into making new tiger biomass, compared to 10% of the energy from the plants going into making new guinea pig. And since tigers are much, much bigger, there have to be a lot fewer of them.

      A tiger’s size gives it a big enough hunting advantage that, well, the world has tigers in it, but necessarily limits the numbers of the tiger population.

        The next step is asking what the natural environmental limits on the human population are, but don’t worry, we’ll find out.

          Nah, we won’t. The world can support far more than 8 billion humans.

          It’s just that the world can’t support 8 billion white humans driving cars everywhere, eating meat, and buying a ton of plastic crap. It probably can’t even support 1 billion of those assholes.

            The ‘I hate white people’ part aside, this is wrong. The earth can not support 8 billion people long term at any level of living standard.

              Nah, the EAT-Lancet report says the Earth can support 10 billion humans, if radical changes are made to consumption habits.

              And mathematically speaking, white people are the biggest offenders on climate, who will need to make the biggest changes to follow the EAT-Lancet report’s advice. It’s not prejudice, it’s just math. White culture is a social construct that causes destructive climate vandalism behaviour.

                EAT-Lancet really only talks about feeding people and under current conditions. But conditions change. Rising water levels and shifting climates are going to be happening in the short term. If you are OK with millions of people starving to death because of a drought or a disease or pest infestation, then sure, live on the edge.
