What is the ideal population for planet earth?

The present world population is 7.6 billion, with 9 billion predicted by 2050, and 11 billion by 2100. Clearly, this is way too many people. Carbon emissions cannot be sequestered, food production may be able to keep up if we consume wheat, sugar, rice and corn. But, meat and garden vegetables will be available to very few people. Fresh water, and sewage treatment will be issues too.

Reduction of the future population may occur from disease (the red death), nuclear war, famine, etc. Assuming that will happen, what is best size population for a stable and affluent Planet Earth in the future, say in the year 2800?

Help us keep this site organized and clean. Thanks!

  • I think where we are now is possible. We currently have enough resources for everyone to survive off of, we just need to distribute it properly and stop using so many damn fossil fuels.

  • How many people CAN the world support.
    Or, how many SHOULD the world support.
    With modern technology there is a whole lot of food capacity.
    That said, people are bad.
    Not one by one, but as a whole.
    Including me.
    The world is better off without any.

  • I remember in high school in the 60's the population was 3 billion. Now its well over 7 billion. The 3rd world needs birth control in the worse way.

  • I don't know, I'll be dead by 2800.

    If we want to have a safe population, we need to start by educating the next generations properly. That includes actual sex education and not some gym teacher handing out ditto sheets or some half-ass pedo teacher who is riding on that tenure.

    Let all living enjoy plentiful resources and privacy!

    Humans are the smartest species. We should use our intelligence wisely, and stick to maintaining a balance and respect for nature.

  • There are ways that Ebola could be spread very quickly. I can neither confirm nor deny any detailed information pertaining to this. I do agree that given random events, flu has a higher likelihood of hitting global pandemic levels.

    Anyway, back to the post. What population level do you think would be ideal in the year 2800?

  • Presently, the problem is not the population, but our lifestyles. 11 billion could have a pretty good life if we get rid of all our political boundaries and our vehicles.

    • Get rid of vehicles just to cram in more annoying and useless humans? No thanks.

      Why sacrifice the freedom and the fun in life just for more bullshit?

      Quality of life > population.

  • Most scientists actually think the earth has a maximum carrying capacity of 9 - 10 billion with some thinking it can support up to 16 billion and some think we are already overpopulated saying the earth could only support 4 billion. I believe that the earth is doing fine right now and can still hold a couple more billion people.

      • Africa is bad because a lot of the land there isn't suitable to grow crops because 25% of the land of Africa is desert that combined with the fact that most of the countries in Africa doesn't have the same technology as the rest of the world makes it harder to live there. India is bad because of how densely populated the country is. They have almost 1.5 billion people living in a country that is only 2% of the earth's land mass, of course they are gonna have trouble providing for themselves.

        You question though asked what would be a stable population size in 2800. By then it is my belief that the human race will become much more advanced and with those advancements be able to better support themselves without harming the environment. We are always making advancements and are always looking for ways to limit pollution by limiting the amount of green house gasses that gets into our atmosphere and by finding new ways to reuse waste products.

        • My question was IDEAL population. A stable and affluent population will be smaller than a population that is stable yet impoverished. I'm thinking by 2800, 500 million would be a good critical mass to have enough geniuses born to find solutions to difficult problems. A higher population than that would be more dead weight than is required, hence a drag on the standard of living.

          • That's not how things work though. Limiting the amount of people would not make people smarter especially if the cause of which was something outside of human control. If the population was 500 million most of those people wouldn't have the time to spend on innovation and as a result things would take a lot more time to get better. Part of the reason humans are so advanced is because we have so many people in the world. The more people you have the greater the chances of someone coming up with a new idea.

            Think of humans as one big artificial neural network. In a neural network the more nodes the better the chance of solving whatever problem is given in a shorter amount of time. You have to also think that almost all of the innovations done are done by specialists in their respective fields. If you lessen the population that lessens the amount of people who are gonna be able to devote there time to a specialized field.

            • Except in the year 2800, production and service jobs will be almost all automated. This will enable far better leveraging of intellectual talent. For example, say 2 million researchers are doing biomedical research right now. With no production or service jobs in the future, 2 million biomedical researchers can easily be supported in a population of 500 million.

              Your neural network analogy does have some merit, tho. In the next 80 years, dumb people will continue to multiply. Smart educated people, drowning in student debt will opt to not have kids they can't afford. The drop in intelligence means that humanity's neural network will flicker, and perform poorly.

    • Yes. It will eventually overwhelm the health care system killing everyone in high density urban areas. People that live in deserts will be spared.

      • only a little over 11 thousand people have been reported to have been killed by the Ebola virus from 2014 - 2016. Pretty much all of which has been confined in Africa. Only 11 people have been in the US with Ebola, 7 of which evacuated from another country. Of the total 11 people infected only 2 of died. Ebola isn't really a threat to people outside of Africa and in December of 2016 there was a study done that showed that VSV-EBOV was 95% - 100% effective against the virus making it the first Ebola vaccine proven to work.

  • Ebola is a ribonucleic acid (RNA) virus and multiplies particularly rapidly in its host creating a high pathogen dose. Yes, a mutated flu virus could also put a dent in the population. Both types of viruses mutate. Ebola already has four different infectious strains.

        • Smart enough to understand the racial IQ distribution by studying statistics and accurately interpreting stereotypes.

          How smart can you possibly be for having a leftist vision that people are shaped only by individualism and completely ignoring their genotype, which obviously has an impact on them? It's just as bad as following only the race/appearance, ignoring their individual characteristics. An unnecessary conflict bewteen extremes which make no sense and which will establish no true winner.

          • It's more about cultural upbringing and education. Those things would effect how you perform on IQ tests.

            There's no evidence to show that a certain race's brains are actually better, and more evidence against that.

            Nigerians who are sent over the America or other Western countries do very well in school-

            https://www.chron.com/news/article/Data-show-Nigerians-the-most-educated-in-the-U-S-1600808.php

            Asians are similar, and you know what they have in common? Their parents drill and drive them to succeed in school.

            Meanwhile, ghetto, hood, gang-banging blacks do the worst. Education, honest work, and success are not encouraged.

            I'm done here now. I'm supposed to be trolling on this account, not schooling bigots.

            You wouldn't infer this from my comment, and unfortunate use of the overused and incorrectly used word "bigot", but I'm not a leftist or some liberal dumbass.
