      How many people do you think can live on this planet? What is the current population of our world? How does planet Earth’s ever-growing community effect our natural resources? Is it possible for their to be too many people living on Earth? What if there weren’t enough civilians on the planet? This Horizon special documentary examines whether our planet is nearing a potential population crisis. With the assistance of Sir David Attenborough, a naturalist, they attempt to the answer the complex question “How Many People Can Live on Planet Earth?”

      Sir David has had an extensive career and throughout he has witnessed the human population more than double. Going from 2.5 billion in 1950 to the ever-growing population of nearly seven billion. So what does this mean for us as a society and our planet as a whole? Sir David examines the effects surrounding the rapid growth.

      How Many People Can Live on Earth? Sir David discovers on his journey that although the majority of population growth will stem from the developing worlds, it is actually the lifestyle enjoyed by so many in the West that will actually impact Earth. Some leading professionals even claim the in the UK consumers sometimes use, as much as two and a half time their fair share of our planet’s resources. An unnerving fact when it is considered how the population is still growing.

      Anyway to combine these videos into one that continuously plays?

      This is why I was so disappointed when the Australian government launched the baby bonus to give out free money to encourage mothers to have babies. Majority of births occurred in low income areas where the mothers were single and under the age of 20. Some didn’t even spend the money on their children, but instead used it to buy plasma tvs, to get plastic surgery or on alcohol and drugs. There should be a test to prove whether people are suitable to be parents: they should be financially, emotionally and mentally ready.

      I’m pretty disturbed at population growth, because I know it’s unsustainable. I have two siblings so I’m more than happy to not have children of my own. However, I was horrified when my partner told me he wants a BIG family, at least 5 kids (his grandmother had 12 children!!!). We’ve had many debates and have finally agreed to have two – even though I told him I don’t want to have children. I actually don’t mind adopting children who already exist, but his against the idea of raising “someone else’s kid”. Most of my female friends can’t wait to get married and have babies, but I seem to be the only one who doesn’t give a sh*t

      Same garbage, different year. Club of Rome and Meadows et al published “Limits to Growth” in 1972. The VERY SAME doom and gloom arguments or so-called “facts” were put forth. Their predictions/forecasts? Again, virtually, the SAME THING.

      To paraphrase: “….we are severely depleting our resources. Soon there will be nothing left and our very survival will be in the balance…we must stop consuming and change our ways now…” Sound familiar? Read the book: “Limits to Growth,” published in 1972; it’s there.

      The predictions made? Oil, gold, tin, copper, zinc, and many other commodities were supposed to have been depleted by the year 2000. Hear of any catastrophic shortages or imminent global collapse due to lack of oil, tin, nickel, gold, etc. – in the last 10-20 years?

      Just like global warming….It is all a HOAX!!!
      The logic is bad, the science is bad, the facts and/or data are bad, and the educated idiots promoting doom and gloom are bad. I wonder if these people are reincarnations of tribal witch-doctors and/or shamans…

      What is more destructive than overpopulation is over consumption and an unappreciation for our environment. That is the core problem. This video makes me further understand why some governments encourage war and death, it is a form of population control. It is better for all governments to be straight forward with a limited child policy than to trick you into believing you have more freedoms than you really do. If they are to punish familes for having many children they should also punish those who overconsume.

    • Dan

      Yes because I mean how it’s not like earth can support a unlimited potential of people.

      You’re telling me the earth can support 1000 billion people and we have limited land and water?

      I myself don’t believe in global warming but I do know that the earth can’t support a unlimited amount of people. Also why are you calling them “Educated idiots” why the insults? Would you like to give us references to actual proof saying their science facts or data is bad?

    • J D Auran

      I suggest you re-read the post CAREFULLY. Note, just as carefully, what IS said and what is NOT.

      A great deal is missed by disregarding the book cited. If specific hand-holding in the references area are required – you’re unlikely to understand or appreciate the answers anyway.

      Ah! We’re all gonna die!!!

      yep, all gonna die

      J D Auran – the people of Rome were always terrified of the Barbarians at the borders of the Empire, some said they would never come but in the end Rome fell. Just because your book was written 40 years ago it doesnt make its predictions less true, the earths resources are finite – the growth of populations technically infinite. 10 people can not comfortably live in a 4 bedroom house.

      It brings me great grievance know our fate. All this knowledge, and no controlling action to the people. The people that run our government should control the actions of the people in order to keep balance in the world between man and environment.

      Environmental ethics should rule given our current state. we’ve become out of balance.

      I hate the way this world is being governed, and every one and everything is going to pay the penalty for our actions as humans.

      We’re a living virus on this planet. In my own educated prediction, this is the last century of humanity living on planet earth if we continue on this destructive path.

      I hope that someone creates a virus or through some contact creates a virus that has predominate effects on the human population.

      As I study environmental biology & ecology I find myself asking the same question, “Why doesn’t anyone care?”. Great thinkers and philosophers warned of the consequences that would arise from our actions (overpopulation, resource depletion, over consumption), but nobody actually listens. I am begining to understand why this is the case. We are all so far removed from these problems, we can’t seem to do anything about it. Everyone my age is concerned with partying, having friends, having a fancy car and fancy shoes and the newest coolest hairstyle. This materialistic lifestyle promotes an infantilization of society and distracts us. Nobody will ever care about any of these enviornmental issues unless we cancel their favorite t.v. show and force them to live the way people do in developing nations.
      The human species will perish at the mercy of the natural world. After we are gone, the beautiful trees and species will thrive.

    • Aramawi

      not bad, you can definetly tell the author went to some length to put this information together, but there are a few things he didnt include; the foremost being the amount of people that die everyday from famine, disease, war, and even natural causes, to counterbalance birthrates. There is the prosepect of building communities on the ocean if we have fully inhabited our cities, there is hydophonic farming if we use up all of our top soil and there is desalinization of the oceans if we run out of clean water, the author didnt mention human ingenuity and technology as a solution to meeting the demands of a larger population.

    • jessec

      People like you make me worry even more. Imagine 9 billion ignorant and blind to care for. Who wants to work and then spend more then halve their income to keep these kind of people alive when there old. An assumed answer let’s make more kids to take care of us when we become blind and ignorant. I hope I won’t drool and shit at the wrong time to much.

      Cheers forget everything and sing along.

    • jessec

      Let’s stick a tube in our ass and stack up in rows of ten by ten maybe if we stay quiet and use each other’s body heat we might live another hundred years.

      Please pass the plastic tomato I want to lick it again.

    • jessec

      I hope that didn’t come as a surprise to you.

    • Cynthia L. Leet

      I find this essential issue hard to face because the future seems so bleak, yet it is extremely important. Humans are dependent on and part of the natural environment. Destroy it and you destroy us. I am grateful to David Attenborough to have put together this Horizon program that speaks about the carrying capacity of the Earth for humans because it puts the issue in simple enough terms that the average person can understand the problem and possible solutions. Each choice a person makes about what to eat, what to buy, what to recycle, how to travel, and how to vote impacts our use of natural resources. Collectively, these decisions can have an extensive impact on our lifestyles and our children’s futures. I am 60 and expect to live about another 30 years. Our decisions matter.

    • Austin

      I like how he starts out saying that he cares about the animals habitats being destroyed by overpopulation then launches straight into all these human problems of overpopulation. Did he mention one species on the chopping block? And Ive heard quite enough about Global Climate bs. The guy at the end says the temperature will raise 2 degrees and this will devastate food production. How so? Will the farmability of more land in colder areas hurt food production? Will increased c02 which is known to actually boost plant growth (which is why it’s pumped into greenhouses) hurt food production? I don’t think so. Ok I’m not saying have families with 15 kids that is crazy, however don’t use a bunch of misinformation and scare tactics. That is called propaganda.

    • Austin

      O ya and one more thing Just so people know in the past when the Earth was all around more tropical and warmer the equator wasn’t hotter than it is today tropics will remain about the same temperature because of extreme humidity and distance from the sun. Distance from the sun I say it again because people forget that actually changes and is the most important factor in determining climate factors. That’s all I really have to say about this movie, and I call it a movie for a reason.

    • terry beaton

      You seem to have some strong opinions about Global Warming. The last time I heard such a heated disagreement with 95% of the words scientists was the Catholic Churches position on the earth being the center of the universe. What does Foxnews have to say on this subject? They really are the current voice of truth and fairness in the world, right. Pretty soon we’ll be seeing this new force and everyone who has “tea” with them influencing major decisions in Washington on this and other even more vital matters. That’ll be fun…

    • Monkey Man

      This Doc makes me think of our only real solutions; reduce the population, or (only hinted at in this film) become an interplanetary species.

      Stephen Hawkings for one believes that “having all our eggs in one basket” will not only stress our natural resources to the breaking point, but also leaves the entire human population open to mass extinction from outside forces.

      I agree with both these views, I’m just disappointed that every generation currently living will never see the latter.

    • Inga Kubiliute

      people need to start to live not only for them selfs…

    • tim

      most of what you say is missing is in the documentary. After war, disease, natural disasters and so forth the population is increasing by two people per second.

      They did mention technology as part of the 3 step solution along with population control and stopping over consumption. But technology alone is just a means of pretending we are smarter than we actually are. It’s like painting a rotting house. The whole world needs to become more educated, not just a few scientists with a breakthrough.

      There are a lot of good intelligent people in this world. Let’s just hope there’s enough to outweigh the ignorance.
