How can we sustain infinite growth on a finite planet?

Human population growth is a serious problem that is growing by ridiculous geometric progression. Everyday approximately 200,000 people die, and in contrast 450,000 are born. That is a staggering 250,000 new mouths to feed everyday! We cannot support infinite growth on a finite planet! We're running out of land. Thousands of square miles of rain forest are gutted every year for palm plantations to produce palm oil so that masses can be sustained. Fresh water supplies are in limited quantities. Polution and contamination abound. Why do people ignore the realities of where we're headed? It frightens the crap outta me. It appears as though the discovery of oil is when things really took off. Oil ultimately led to the internal combustion engine so that huge amounts of land could be cultivated. Pesticides and fertilizers were also made possible via oil to enhance production yields. As well as affecting the pharmeceutical industry to produce vaccines. It's not natures way.

    Sep 27 2012: To come back to the original question, Rockstrom et all have shown that at least 3 out of 9 planetary boundaries have been crossed (and the changes are irreversible). For an interesting read on this : http://en.wikipedia.org/wiki/Planetary_boundaries

    Kate Roworth of Oxfam International proposes a doughnut hypothesis to tackle the situation and I have difficulties agreeing with her. http://pabitraspeaks.com/why-a-doughnut-now/

    Sep 24 2012: Do you wonder if the earth will self regulate? That the "natural" disasters that come from global warming will help to remove some of the "blights" on earth. It is scary and seems random- I think if we begin to make some of the changes in our policies and behaviors maybe we can regain some control, but in the end- we have very little. The earth chews and spits out now and then what isn't working for it I think.

    Sep 24 2012: Fix the loop of sustainability. Finding solutions is not the main problem, but making everyone else to take them seriously is.
  • Sep 24 2012: We can't sustain infinite growth on a finite planet, but I'm hopeful that the population growth will plateau, the ingenuity of humankind will come up with solutions to our resource problems and that all of this happens before we have pushed the ecosystem to its brink.

    I see mentioned below that the average number of kids a family has is diverging to two. This video by Hans Rosling makes a very strong case that population will eventually plateau as the standard of living and eduction is raised for the poor. http://www.ted.com/talks/hans_rosling_religions_and_babies.html

    We already have the technology to supply energy without the use of natural resources, but currently renewables are too expensive. We won't truly see them catch on until there is a shortage of natural resources, driving up their costs, or governments start taxing the use of natural resources. People will make decisions that financially benefit them.

    Again we have the capability to create clean water, it is just an energy intensive process.

    I'm no ecologist, but I do believe the environment is pretty resilient. I've seen some pretty impressive restoration projects. My only hope is that we can keep everything in check long enough for the population to plateau and for green technology to surpass the use of natural resources. I love the outdoors and I hate to see the damage we've caused.

    I don't like what I see, but I am optimistic...
    • thumb
      Sep 24 2012: Yes. I think:

      (1) Two kids per couple is the optimal number today according to our instincts.
      (2) There will be more than plenty of resources and energy if we quit SILLY invalid happiness.

      Be happy validly!
  • Sep 23 2012: We are talking about very difficult , sometimes even unimagined techical problems more than political ones. However, if you review the history of the last hundred or so years, we started out with zero airplanes, most people saying it was impossible to fly, and within 60 years, we managed to send people to the moon and bring them back alive. (!) During the same time period, there was this ongoing problem about Palestine, and the Middle East in general. I submit that the absence of ANY significant political progess in that time is a proof that technical problems are much easier to solve than political ones. And by the way, it is not necessary to go 600 light years away to find some alternative habitations. Within our own Solar system we have various possiblities within reach. Therefore I am suggesting that , quicker than getting Arabs and Jews to agree on anything, would be the project of terraforming some planet to sustain humans.
    • Sep 24 2012: I like your comment about flying. Our concerns and fears will be so different 50 years from now. What we can only dream today will be reality tomorrow.

      Do you really think it would be worth the effort of terraforming a planet when we can't even manage the one we have in a sustainable way?
      • Sep 25 2012: Andrew: rmember the "mismanagement" you are talking about is mostly political nonsense. if it were left to the kind of people who managed the moon project, we would be doing a lot better. Examples : going Green is fine, but Ethanol is a political and financial scam. It wouldn't be nearly as hard to convince techno-geeks of that, if indeed any need convincing.. Thorium LFTR power is the answer to a great many of the management problems you are talking about, but the details about it are distastefful to ordinary people, so they just say "Well , if it were that good we would have done it already." About as stupid an answer as could be imagined, but subscribed to by many, some of them with "Colllege degrees". At the very least, Terraforming would be a venture popular with the group that was doing it; sort of like the morale of any group doing somethng new and dangerous. Windmills and solar panels are fine too, but there is simply no way they will solve the energy problem, except theoretically. Try telling that to a Green Luddite liberal arts grad. Then there is the matter of conflict and warfare. I vernture to say that in a terraforming situation, such a waste of time and evergy simply wouldn't happen, not until it had been a success for a hundred years at least.
    • thumb
      Sep 24 2012: I think:

      (1) Terraforming a planet is almost impossible for the extremely fragile humans of ultra-high accuracy.
      (2) There will be more than plenty of resources and energy on the earth if we quit SILLY invalid happiness.

      Be happy validly!
  • Sep 23 2012: Let me share with you my cosmogony; the way I see this issue. In the past, people used to have many children, it was a part of their "modus-vivendi" for many reasons. First of all, the circunstamces they lived were very different: there was a lot of land to even explore, medicine was very limited and therefore live expectancy was very short, having many children was a way to increase the work force in the typical family business, currents of thought, in those days, said people had to dwell earth and everything in existance was made for the use and joy of humankind.

    Since the industrial revolution until now days, human's life has changed drastically. All the advances in science: medicine, technology, sistems etc. have contibuted, not just to improve human's lives, but also, unfortunatelly, jeopardizing our own supervenience, like the following reasons:
    1) Medicine advances have impulse an exponential birthrate and overpopulation. We have adapted so good to this world that, now, we are a kind of cancer or plague to our planet. I have friends that have known their great-grandparents and have children as well, that is: 5 generations living in a same period of time.
    2) Technology, have create us many needs and thus we have become very consumerist and materialistic society, having to consume huge quantities of resources, sometimes unecesary; some others unificiently, creating ecology devastation and inmbalances in our environment.
    3) Systems like economy have made many injustices. I believe this is the greatest flaw in this issue because it has create a greate gap between societys, countries and people. And the problem with this is that this creates ignorance as there exists a correlation between lowincome - low, inefficient education or non-existence at all.

  • Sep 23 2012: (CONT'D)

    So, just to conclude, I think birth control is definitely a very important part of the solution. But it's missing the how. How can we control birthrate? Let's be reaasonable, we can not imposse people not to have children. It might be, probably, something that future generatioms will have to do as a way of survivance if we keep these birthrates. And, yes, I agree wars are one of the resaults from many of our exesses. Although we can not take it as a solution to control overpopulation. That would made us regress instead of progress as society and as developed beings.

    I believe the answer for many solutions for today's issues is EDUCATION; good education. Education that not just permit everyone have acces to the several fields of knowledge, but also that teaches ethics and good values that can inspire people and society to be be better; a "formative education" that can change the world.

    I know it might sound very naive, but it is a fact that good education change people's way of thinking and way of living.

    Let me put you an example. In Mexico, my country, we can find a huge gap between rich and poor people and we can clearly see the correlation, I was talking you about, good or competitive education - high income vs inefficient education - low income people, and the huge gap in the way of thinking. My parents' made has four children and two grand-children at the age of fourty, this is not an isolated case, actually it is pattern we can observe. Low-income people are more ignorant due they're enable to have goog education what they get is just a rickety education, and we can say it's one of the reasons they have more children at younger ages. If we could help improve the education sistem and let everyone have a formative education, we could help a lot in solving this problem. Another way to improve education are these kind of movements; TED's movement, where people can enrich their criterion and perhaps inspire society to be better.

  • Sep 23 2012: (CONT'D)

    Another way to improve education is by improving the entertainment industry, as this is, every day more and more, the one who educate and transmit values (good and bad) to society. That's the reason I started to write scripts; to make stories that could inspire people to be better and thus contribute to cociety for better.

    If we could convince people to have less children, perhaps one or two; and if we could convince them, if they want to have children, have them at older ages, perhaps at 30's, I'm positive we could save the world and have a green planet again.

    The worst genocide of tomorrow is the ecocide of today.

      Sep 24 2012: Yes! I agree:

      (1) The “optimal point” of kid number per couple has changed instinctively from many into 2 or less for keeping our DNA alive --- the goal of our life.
      (2) We ourselves consume our own planet INVALIDLY.
      (3) MONEY destroys: empathy --- symbiosis --- peace --- humankind.
      (4) EDUCATION makes people know the “invalid happiness” leading us to self-extinction.

      Be happy validly!
    • Sep 25 2012: I agree with the opinion that education is the answer for many of today's issues. If we can create wide access to high- quality education that not only teaches math, science, and reading, but teaches problem-solving, communication, creativity, and other 21st century skills, we'll end up with a generation of thinkers, designers and innovators that can take on our current and future problems.
  • thumb
    Sep 23 2012: Increasing populations will eventually force us to act. I guess that's what we are waiting for.

    However, as far as preparing for the future I think we can break it down a bit.

    1) Shelter
    The amount of space needed for each human is rather small. We aren't really talking about a "lack" of anything as we haven't even used all of the available land here in the United States.

    2) Resources

    This "danger" has existed for decades. I don't think we are in any danger of a crisis like you attempt to state here.

    We definitely have problems. I do agree that the environment needs to be our focus. However, how do we pay for green industry? Our problems extend far past "waking up" and almost dive into "how do we wake up"?

    Green industry is not a matter of choice...or something we are waiting for people to accept. It is very difficult to imagine how we plan to maximize industry...and manage environmental damage.

    Let's also note the positive role oil plays in our daily lives.
  • Sep 22 2012: accually it was when we learn refridgerate food that our population exploded
  • Sep 22 2012: I raise worms in my compost pile. They improve fertility of the compost. A friend of mine told me that she read that when food runs low the worms stop reproducing. Will we reach the intelligence level of worms before we exhaust the resource base?

    The evolution of intelligence is a large topic. One aspect is the issue of unrecognized self image being mixed up with self, or who we actually are. The self image is a mentally created illusion of who one thinks one is. The actual self is experienced as the kinesthetic sense ( kinesthetic - definition of [ The sense that detects bodily position, weight, or movement of the muscles, tendons, and joints. Greek k nein, to move ... ) of being in a body fulfilling biological needs.

    People functioning out of self image are competitive, aggressive, with disregard concerning the consequences of their actions upon the larger field of human well being. This is because once one is disconnected from the kinesthetic self one feels insecure. Insecure because the self image must constantly be maintained through accomplishment and acknowledgement or it begins to fade. This results in a feeling of anxiety, fear and a feeling of doom boarding on death because one has identified with a false self which can be killed off by not being validated and reinforced through accomplishment.

    From my perspective we have a ways to go, but some of us will survive to reproduce again.
  • Sep 22 2012: By completely reconsidering our concept of growth.

    Instead of economic growth, what about the growth of the 'sustainability bubble' (not in the perjorative economic sense, but in terms of what the bubble grows to encapsulate)?

    That is, the more energy and the more materials and technologies we are able to bring under the banner of 100% sustainability, the more real growth we have.

    At this point in time, we're in a negative growth phase in those terms - because we're making things less sustainble through our actions.

    Another angle to consider growth from is experiential and information growth. Imagine high quality VR technology... essentially a maturation of visual/sensory computing technology found in games; it's a system that will provide experiences independent of material consumption.

    And ultimately, that's kinda what the human experience boils down to - a series of interlinked and interconnected sensory experiences. The experience of conspicuous consumption can be easily replicated in virtual space - and in doing so, it can reduce the importance of real conspicuous consumption.

    How much value is there in a boat, a big house, a fast car... when all these things are difficult and expensive to purchase and maintain - and there's an alternative where you can experience all these things and better at next to full sensory fidelity in VR?
  • Sep 22 2012: Good Question Jake .... being a "Half Glass Empty" kind of cautious thinker, I decided to skip the "having kids" part of my life. (Luckily, baby-sitting is enough to satisfy my maternal instinct.) Unfortunately, my twin brother had 4 kids and so .... he seems to have had my 2 for me ... or at least his various female partners have. Lordy-Lordy ... enough about my family!! The point is ... sigh ... I have serious concerns about the Earth's ability/Humankind's abilty to sustain (quality of) life on this planet. For the "Glass is Half Full" folks (like my brother) I hope you are right! In the meantime, I will try keep the three R's ... Reduce-Reuse-Recycle and try to not take more than I need in this life ... not easy to do in this very materialistic culture ... but I will feel less guilty if I at least TRY to leave something for my nieces, nephews (and for yours.) We have a small planet with some big problems ... Hopefully, with all of these people we will increase the odds of finding some creative innovators with real solutions.

    I have one suggestion: Provide quality education for all girls, boys and people (in general) . We will
    (statistically shown) have less population increase over time and the people will generally be more capable of meeting their potential.
  • Sep 22 2012: In the advanced countries, we are experiencing the oposite: a population crash, to the point where people are wondering how we are going to avoid a big labor shortage. In Japan, they are banking on robots, since they don't want to destroy their culture with immigrants. Have you noticed that some countries have such a low birth rate that they are not in danger of being swamped by population growth. So if the Industrial Revolution continues, and Feminist ideas spread, as they have been doing, the problem should gradually lessen. It all depends on cheap energy, but luckily that problem is on the way to solution as well: the Chinese are undoubtedly going to make Thorium LFTR power plants work. You'll hear about it in a few years, when they start shutting down their coal fired power plants, and replacing them with much cheaper Thorium power..
  • Sep 22 2012: To control population, quit making advances in medicine, don't save the children, feed the starving, have a socialist society, quit foreign aid, and quit intervening in foreign wars.

    Sep 22 2012: Jake, here's an interesting study that might apply to your question about Infinite Growth...etc,. Poverty of course has a tremendous affect on anything we do to create a more sustainable future.

    http://online.wsj.com/article/SB10000872396390444165804578008311635287522.html

    extract: "Moving low-income families out of poor neighborhoods doesn't help the families escape poverty, according to a new study, but it does make them healthier and happier.

    In a paper published this week in the journal Science, researchers from the University of Chicago, Harvard and other institutions, studied the effects of Moving to Opportunity, an experimental federal housing program in the 1990s that offered housing vouchers to more than 2,000 low-income families so they could move from impoverished areas into mixed-income neighborhoods. A separate control group had similar demographics but didn't move to mixed-income neighborhoods with the help of vouchers..."
  • Sep 21 2012: infinite grow will be limited by war,
    that's what happened over and over in history

    so you dont need to worry,
    • Sep 21 2012: That is an old fashion way of thinking about population control. If all people think that population control has to decrease by any other means but wars, then we all are a bunch of genocides, incapable of making more creative solutions and then we might desserve to be wiped out from existance.

      Do you really think so?
      • thumb
        Sep 22 2012: No!
        Please do not do that!

        Today's war will very probably lead to human extinction rather than population control.

        Will it be far easier to quit the silly invalid happiness to control it?
      • Sep 22 2012: it's not old fashion, it's still gonna happen , because you know, not all country in the world are developed country who has technology to prevent hunger , many countries still importing food, and when the exporter countries cant supply them anymore, what do you think gonna happen ? peace ? thinking about how to make food ? oh come on, people cant delay their need of food more than 3 days, many could do but not all, and according to human natural behavior, yeah there gonna be massacre, kanibalism, etc

        it's inevitable...you know not all people could use their brain in the crysis situation, most people will use violence...

        the effective way to prevent it is by birth control, government need to make a research about how many food vs human a country can supply so they can decide healthy birthrate value, so gov can decide whether it's time to only have one kid/family or more or not even one

        if they have surplus food then no birthcontrol but if there is a potential of minus food supply I think gov need to apply those 1 kid 1 family is enough
        • Sep 23 2012: Thank you so much for your response. You see, you're looking out for ideas to solutions, like birth control, it's just that it seems you haven't completed the whole idea.

    Sep 19 2012: We cannot. Period. Infinite growth is a consumer economy bubble that has burst already but it seems we know no better. The effort is now how much we can delay the Malthusian collapse by squeezing out the dwindling resources of earth using more advanced technology.
    About a decade ago Humans, as a single species were appropriating close to 40% of the total terrestrial photosynthetic produce - I do not dare to know the current statistics. The linear growth paradigm is a mass insanity just like praying for a miracle cure of a cancer patient without resorting to therapy.
    I do not want to sound overtly pessimistic by saying that even the natural cyclic growth-decay-growth is also an entropic slide down to an eventual stop.

      Sep 20 2012: Yes;
      It is the "invalid happiness" to be blamed.
      Humans need only valid happiness to keep their DNA alive.
      They use their instincts out of the valid scope formed 10,000 years ago.

      So, just quit the invalid happiness and everything will be OK.

    Sep 19 2012: That depends on to whom the term "we" is referring. You and I cannot do diddly one way or the other, Jake Maddox. Let's suppose that "we" are 100% of the human family. Now which direction we take depends on what on this planet we agree is worth sustaining. Some would have us wait for a war or plague or rampant starvation, judging by some of the entries here. Actually everything we need to know is what we all should have learned at Kindergarten age. Share. Don't fight or keep things to yourself. Hold hands if we are going somewhere uncertain. Celebrate each person as another you. Don't purposely hurt people. If you accidentally hurt people, say you're sorry and mean it. Get and give hugs every day. They're free and good for you. When there is not enough of something to go around, the sensible thing to do is take turns.

    Every day there are billions of people trying to pass on these ideas. We need to revisit this lesson and practice compassion. Compassion equals health from self to community. Empathy is not a long lost art. We can always at least copy the behavior we think is good. Mirror neurons trigger mirrored emotions. If you watch Schindler's List, follow Schindler's approach, not the Nazis.

    It's a given that the Brown economics is the only one we can practice at this point if we don't want to torch the planet in the next few hundred years. Perhaps someone will write a way more extreme economic thesis based on ecology.
    And when they do, in whatever country they do it in, perhaps they will be placed in prison, because we all want our toys and our heat and our electricity, and who's going to tell us any different?

Well, the cheap energy solution has already been invented. The only reason we have not been producing it for the last 40 years is ignorance . You'll be happy to know that the Chinese are developing our Thorium LFTR power designs as we speak, they plan to have 2 demonstration plants going in about 3 years. We could have done this, but the US had, and has, other interests, like football, and Creationism, etc. See Youtube, Thorium LFTR power if you want some details..

    Sep 19 2012: I am inclined to agree with G. Barker's first sentence "The simple fact is that we can not." But I will put forth the undeniable fact that we must look off world for a future that will sustain continued and uninterrupted growth. If it is infinite expandability that you desire then we must set our sights on the infinite universe.
    • thumb
      Sep 20 2012: But.
      To quit invalid happiness is much easier than set our sights on the infinite universe.
  • Sep 19 2012: The simple fact is that we can not. What is not clear is if we will asymtopically approach a sustainable plateau or if we will overshoot and suffer a rather horrible die off. Right now I am thinking overshoot.
    All we need is for a general increase in health care in some high growth population centres and millions or perhaps even billions who would normally die will live to consume resource, food and water. That can cause a spike in the population that if acompanied by an unfavourable climate change will spark a population decrease.

    Or a space faring race of hungry aliens can come down and harvest us (as they do evey 100,000 years or so, when our population explodes).

    I'm not sure which future I would like to see less.

      The easy and happy way to go is to quit silly "invalid happiness" and save more than 90% of resources on the planet.
      Wrong?
      • Sep 20 2012: No, not wrong, but also not easily achieved. This is another case of the tragedy of the commons style of problem. If I break the rules, I get a disporportionate gain over the loss that the public sustains.
        Also, in the long term (and as a species we really should consider the long view as more important than the next quarter) unconstrained exponential growth is never sustainable. Sooner or later the population of the earth must stop growing, sustain itself at that level or (more probably) fall back to some lower level that the earth can comfortably sustain while maintaining a healthy eco system.
        I personally think that given our blatent disregard for the environment needed by other species and our overfishing of the oceans, we are already far past the population number the earth would be comfortable with.
  • Sep 18 2012: There is an interesting documentary by Lester Brown on this topic (narrated by Matt Damon). This is a link to the free online book: http://www.earth-policy.org/images/uploads/book_files/wotebook.pdf

    Myself, I think there is a tipping point that the world will reach, beyond which it will be impossible to recover. However, I do not think that humanity's course to this point will be very direct. When things go wrong, people will try to fix them. If people somehow determine that life is sustainable at current population levels, I don't think that maintaining the status quo will be very straightforward either. The worst case scenario is that we have passed the tipping point and that humanity is currently in decline and on the way to extinction. That would not be straightforward either (barring some kind of cataclysmic event), and outright extinction (i.e., zero human beings) is pretty unlikely I would think.

    The question does not center on the survival of humanity so much as on the quality of life we and our progeny enjoy while on this earth. How do we want to live before our star explodes? An interesting question: Considered as a single organism, how far is it even possible that humanity is in charge of its own fate? How much sentience and self-awareness can we attribute to the human organism?

      Sep 20 2012: Yes.
      Not far, humankind will be in charge of its own fate if it knows what the invalid happiness is.

  • Sep 17 2012: There are ways to get the poblem of population increase and the rate of increament is highly reconizable with the limitd supply of resources. The ways to contol the growth has been developed as well as the implementation is taking effect in few regions.
    Still there is a large mass that is to be made aware of the problems arising due to the growth of population.
    We just need to wok on that mass to contol the population.

    The reason behind the increasing populaion can also be not ignored as well !

      The reason behind the increasing population is the invalid happiness.
  • Sep 16 2012: is time to begin to be aware of the birth
  • Sep 15 2012: Your question does not fit the dialog you write after it. Question should of been why we cant support infinite growth on a finite planet. Also the word 'infinite ' is out of context, should be unrestrained. Word can only be used in astrophysics and even there it is questioned.
    • Sep 17 2012: The use o words was understandable Mr. Walter. The wod finite can be made sure regarding the resources available on the planet Earth as well as the consumption can be measured as nothing today is for free.
      Now for the word 'infinite' the population is growing at a tremendous rate in various areas and the there is a pat of the population that is not recognized.
