Earth's Population To Hit 7 Billion This Year

MikeChino writes "The UN Population Division just announced that the world's human population will hit 7 billion by Halloween 2011. The increase of one billion people in the past 12 years is worrying, especially since the global population only reached one billion total in the early 19th century. In the next 20 years, our population growth is predicted to rise to 8 billion people as our demand for food increases by 50 percent, water by 30 percent and energy by 50 percent." Not everyone finds it to be worrying per se.

      With increased energy generation, food production and water purification?

      Currently, we still experience exponential growth. Even the quickest growth figures of the UN and other institutions do not predict that to continue for much longer. Either we slow it down ourselves to our own people (in peace), or we;ll do it to other people (in war)... or mother nature will to it to us.

      Maybe we can double the number again... if we carry on on the exponential curve, that might be already in 50-60 years. Then we would have 14 billion people. That would mean 1000 extra cities the size of New York or LA.

      Actually, from an article on energy production I read a while back, the current projection is for the population to stabilize at 9 billion by midcentury.

      (Source) It's mostly about energy sources, but it cites population projection figures in the third paragraph.

      The reason given is rising standard of living. People living in abject poverty (and I don't mean first world slums, I mean abject poverty which is something most slashdotters have never seen firsthand) have lots of kids. Raise them out of poverty to a standard of living that includes such luxuries as medicine, clean water, adequate food and shelter and they have fewer kids. This is human nature, and it's as true for the western world as it is elsewhere. Our population growth didn't slow until our conditions improved, so why should we expect otherwise elsewhere?

      Further to this, it is not necessary for the first world to elevate the developing world in order to accomplish this. They're doing that by themselves. We tend to have a very nineteenth century attitude to the rest of the planet, believing that it is only through our guidance that they can rise above savagery, but the reality is that with the exception of countries held in poverty by war, corruption or constant disaster, most of the developing world is quite capable of elevating themselves, and are doing exactly that. Note the qualifier about "war, corruption or disaster" preventing this; the Congo remains a bloody mess as do many of it's neighbours, but they aren't the only type of developing nation.

      So we will eventually hit population stability. Now the catch is that the global demand for energy will more than double in the process. Given that many of our energy sources are either environmentally disastrous or finite, this is going to become a problem, as is competition for other natural resources. So we're not out of the woods, but Malthusian predictions about population growth are as wrong now as they were when they were new.

      So this is where I am compelled to insert my rant about population -- there is a very well known, almost fool-proof scheme for reducing the birth rate of any society, but it is at odds with may cultures' traditional values, and it has a generational lag-time, so it requires both courage and vision. For this reason, it is not widely adopted.

      The strategy is this: Send girls to school.

      If women are empowered culturally, and have expectations of building their own lives and careers, their preferences regarding children change. If they are taught to think independently, they will choose partners with similar preferences, and the birth rate will fall.

      Every first-world country has already completed this trajectory, and in many cases, it was wrenching, and the social costs were high, but in the end, these societies attained a very high standard of living with a low birth rate.

      The good news is, in most societies in the world, this is already underway. Increasing wealth and the perpetually-rising middle class helps a lot with this. It's likely that, in 100 years, we will be wringing our hands over how to continue to grow the economy in the face of a shrinking global population.

      The pre-requisite to sending girls to school in most of these societies is giving the family the financial security that they can risk losing that girl as either a worker (e.g. on the family farm) or as a future source of dowry income.

      "It's likely that, in 100 years, we will be wringing our hands over how to continue to grow the economy in the face of a shrinking global population."

      Why? The only reason we need to continually "grow the economy" is because the population is growing. If we had a stable population, we could have a stable economy and relax a bit.

    I know I'll get down rated for this, but with the concerns of global food supplies not being enough, and the growing global population, should we REALLY be trying to save people from starvation who will never be able to provide for themselves? Starvation is the thing that keeps societies from growing faster than the increase in food production, so why encourage third world countries to continue to increase their populations when they can't feed themselves?

    There is a basic concept, if you have a resource, trade it for a resource you do not have, and that includes money. If there is an entire nation that has no resources to trade and they are not capable of growing their own food, then the population will starve, the population will go down, and things balance out. Helping rebuild after a natural disaster is one thing, but if after 20+ years a country can't recover, then why should we continue to help? The world as a whole does not need money pits, and the world as a whole does not need a "food pit" that will never be able to trade resources for food.

    Helping people in your own country would make far more sense, since if you can elevate THOSE people out of poverty, they may be able to become productive and to add value to society as a whole. If you want to adopt people and bring them into your own country, then fine, bring them in, and make them productive.

We invaded them, and tried to force cultures on them that they didn't want, need, or understand. Then we took everything they had, told some of them that they were in charge and that we'd back them up if anyone tried to screw with them, and came back periodically to keep making things worse.

    I do have read "Limits to Growth: The 30-Year Update", the 3rd edition of this report written by Meadows' team.

    The point is that they were remarkably right in their first report (1972).

    If you don't have much time, at least read the book introduction and/or the abstract of this short study: A Comparison of `The Limits to Growth` with Thirty Years of Reality.

    Contrary to popular belief, The Limits to Growth scenarios by the team of analysts from the Massachusetts Institute of Technology did not predict world collapse by the end of the 20th century.

    The whole book is very interesting, it has many facts about humanity Earth "burn rate".

    What you should keep in mind: even with VERY optimistic discoveries, a good deal of technical breakthroughs, wise politics... in the very next decades we will face a growth halt and a decrease of average well being, production, etc. We could have maintained the well being and the population if we had done the right thing in 1990, but it is too late now to avoid this decrease.

    We're in overdrive since the 90's, has many over studies show, often stated as "1,5 Earth needed". And no matter how optimistic you are, how strong your faith is in technical advances, this won't make ocean fish replenish as we fish more and more with advanced techniques, this won't make available oil fields expand as we discover less than we pump out (even with more advanced techs), this won't make damaged farmlands heal as we over-exploit more and more lands, etc.

    The analysis shows that 30 years of historical data compare favorably with key features of a business-as-usual scenario called the "standard run" scenario, which results in collapse of the global system midway through the 21st century.

    So where the point here ? This discussion is about Earth population but without any reference to this Earth simulation where all scenarios show that we're heading to a population decrease in the next decades.
