The world's human population is growing too fast for the planet to sustain it. But just how many more people can exist on Earth until it reaches its breaking point? That's the central question of How Many People Can Live on Planet Earth?, a sobering BBC documentary production which is hosted and narrated by internationally acclaimed naturist Sir David Attenborough.

The film argues that mankind is inadvertently setting itself up for a supreme reckoning. A series of experts from the United Nations and other global organizations set the groundwork for this dilemma. They conclude that one of the major contributors to our impending peril lies in the many medical innovations which have permitted substantially longer life spans for the human race. As a result, populations have skyrocketed continuously since the 1800s. This presents a fascinating dichotomy: our distinction may be brought on in part by the very same advances that have ensured our longevity.

As the film makes clear, we are already witnessing the ill effects of human overcrowding around the world. Over a billion people do not have access to clean drinking water, food shortages are rampant, and an international energy crisis continues to plague us. With an estimated 80 million new births each year - many taking place in regions already suffering from severely depleted resources - the world is facing a calamitous destiny that will leave no one untouched.

What's the solution? The filmmakers endorse the need for smaller families and increased access to contraceptives. Renewed investments in education are also championed in the film, particularly for women in impoverished countries, because the highly educated are less likely to have multiple children. Attenborough contends that it is only by following each of these steps that mankind can effectively limit the creation of new life and ensure a sustainable future for our species.

Some viewers may find the perspectives presented in How Many People Can Live on Planet Earth? to be cold and controversial, but Attenborough's congenial manner and scientifically sound approach makes for an illuminating and persuasive argument. He interprets the human species with the same level of microscopic curiosity that distinguishes his studies of the animal kingdom.

  1. This documentary is out of date and incorrect. It turns out that the human population, whose growth has already started slowing, will level off at between 9 and 10 billion in a few years. People are having fewer children, especially in wealthy nations. And more and more nations are rising above poverty.

  2. This is the usual, doctrinaire materialist propaganda on human mating. It presumes that the changes occurring on earth are mostly bad for us and for life on earth. It presumes there is no intention or preference worth considering on earth beyond our own. It presumes that it is a human beings right and destiny to make all the important decisions for him or herself, as well as anyone else under his or her care.

    I say life on earth is conscious but very slow due to it's size and the inherit speed limitations of chemical intelligence. After every major planetary disaster, life has greatly increased in complexity. I say we were generated in order to respond more quickly to planetary threats than the mind of D.N.A. can. Our minds were meant to host the mind of D.N.A. and other spirits, not to serve our personal desires.

    The warming of the earth will result in more arable land than exists now - even with the submergence of coastal areas. If we switched from grains and other annual plants to trees and other perennial plants for our food, we could restore a version of the forests which once covered Europe, China, India, and Bantu Africa. Ditto switching from meat to the shellfish, eggs, etc. diet of our beach combing ancestors. Then we could replace our current sewage systems with one which could store and return our wastes to food growing areas without the vast number of poisonous chemicals the current waste stream includes. These big tasks but are cheaper than the wars we prepare for and fight so regularly.

    Malthus and Hitler told us the proliferation of the weak would destroy us and we must eliminate them to give the strong living space and food. The countries which most adhered to that now have shrinking native populations which must import workers, leading to rising ethnic tension. It's all a con. Let's stop listening to the intelligentsia just as we stopped listening to the state religions of yesteryear. They just spin lies to get and keep society going in the directions the ruling class wishes it to go - and for their own benefit, not ours.

  4. Let me say an example to prove that your idea of high population does risk healthy living in the earth is wrong. If someone makes a cage for his dogs he would calculate its size, because he knows that small cage is insufficient for more dogs. Here he is maker or creater of the cage. But in the case of earth God is creator and He exactly knows about occupants strength. So your worry about high population is vain. Allah has clearly describes it in His holy book Quran that one should not kill their children on the fear of poverty, because I am giving them livelihood for both you and your children. Did you come to the point?

  5. Here are a few supportive facts. Of all the mammalian land-based biomass, we are 33% and the animals we raise and eat are another 66%, which leaves 1% wild. We are now 3,000 times more numerous than were our pre-agricultural revolution Hunter-Gatherer ancestors. Were we to adopt a voluntary one child family contraceptive movement worldwide, then we'd reduce our population to the 1950 level of 2.5B by 2,100, which is just barely sustainable going forward. What this retired physician has had to conclude after a lifetime in medical practice is this: Population Density Stress Is Killing Us Now, through ALL of our myriad and rapidly increasing "diseases of civilization", halted only by our heroic medical and public health interventions costing $3.6T currently, but projected to be $5T by 2030. Stress R Us

  6. Surely the figure is 80 million more of us each year, not 80 million births as mentioned in this quote:

  7. poor people in 3rd world countries are not consuming resources. even if they had a million kids a day, it wouldn't matter. They do not have the power to accomplish this.
    Rich nations come in and offer to help in exchange for their resources. Then they pay the leaders of these countries for the resources, making them very rich indeed. But the leadera take the rich countries wealth and line their pockets. They never pass it on to help their poor citizens who are starving. But we do have an overpopulation problem just the same. We have too many rich white men and women gobbling up the resources of the world.

  9. I read once that if our cities were designed like NYC with public areas for play and whatnot and property sizes like in NYC, the world could fit in the state of Texas. Tight spacing and not enough room but the point is that our poor utilization of our resources and available land is a good reason why we're in this crisis in the first place. Cities are overcrowded, yet you fly over many places in the world and there are untouched pieces of land. I want plenty of beautiful places kept sacred but there are places just outside of cities that are barely touched.

    Look at this statistic: Over 2.2 BILLION tonnes of food are wasted worldwide everywhere, yet kids are freaking starving in third world countries. 2.2 billion tonnes. Half of that waste comes from the USA, where we don't even constitute a strong portion of the world's population. How depressing is that? I learned in my ecology class in college that there are literally thousands of edible species, yet about 85% of our food comes from about 100 and about 95% comes specifically from about a dozen or so from those 100 species. Many of the animals we consume are in fact some of the least sustainable sources of meat. Look at how much water we use for the animals, to clean them and the barn houses they live in, to grow their food, etc. Plus the rainforest issue, don't get me started on how heartbreaking that is, not to mention the soil in rainforests is actually quite unideal for agricultural purposes anyways.

    We don't need to stop people from reproducing, we need better utilization of our resources and start consuming more sustainable species (less meat for sure too). Don't buy into the propaganda made by the greedy elite who want to keep their ridiculous amounts of money and keeping most of the world poor and hungry. We don't need to eat 16 oz steaks, nor do we need a giant plate full of food at every meal. Eat until you're satisfied, not until you're full. Stop convincing the world that death is good for the economy, and life is bad for the planet.

  10. The reason for the worlds problems is not the over population. The problem is corrupt, greedy, and often downright evil people who want it all then blame the people. The media are either as stupid as a drunk sheep or part of the evil group. The reason people are so bad? I read somewhere....oh yes, in Gods word to us "The LOVE of money, is the root of all kinds of evil. Politicians are a special breed of evil and i often wonder if they do in fact have souls or conscience? Recent wars, if not the vast majority, are nothing to do with self defence. Its about conquering, arms sales, power and sex. You will ALL find out some day ( i hope it is soon) that the only Hope for mankind is the return of the Lord of peace. Jesus will destroy every corrupt system on earth and set up his Holy Kingdom which will last for evermore.

  11. Boi Hitler basically murdered almost 90 mil people

    like how does weather compete with that

    The ice age was big

    but Hitler killed off or caused almost 80 mil deaths

    he would've succeeded too if he had just planned out a little more

    so just think about that.....

  12. Some good comments. Whenever this topic comes up I always suggest that those who think its too crowded ought to lead by example and remove themselves.

    No matter how pretty they want to paint it, there are groups such as the free masons and likely others, that want to eliminate the majority of the population. Is Attenborough a free mason? I don't know but they seem to have a bit of control over media and have their minions everywhere.

    Now it wouldn't surprise me one bit that many of the same socialist-communist-"progressive" folks that desire gun control also want population control. That might not make sense on the face of it... But it does make sense when they can get rid of many much faster if you cannot defend yourself. Which of course is the plan. Ask Lenin, Stalin, Hitler, Mao, Pol Pot, Hillary, Obama, Democrat leaders, etc.

    From what I understand, the populations of the western countries are not expanding all that much. Not that many families are large any more, many with just 1 or 2 kids, except the poorest who used to (and maybe still do) get a larger govt check the more kids they had.

    One commenter estimated that at some point they may just spray us from above with contraceptive "for our own good". That is already happening. Chemtrails are overhead most days. The toxic nano-metals not only harm humans but all life. It will poison the soil eventually. Reports of stunted crops have already come in. Then there is still the spread/bombardment with radiation from Japan's Fukushima by air and water.

    Genetically Modified Crops will shorten many a life as will the next world war which will no doubt be about money and power for the war profiteering bankster elite who also own the GMO seed companies.

    Then there are the other type of evil wankers who develop and release various new and old diseases... as well as those areas of the world which sleep with their swine which comingle with their birds causing various virus mutations.

    I am not particularly worried about over population. Just feel sad for those that have little or no means to protect themselves from the onslaught and those who still think their govt is good and in general is there to protect them. There is too much evidence to the contrary to believe that ...but they still do.

  13. This is sad, but I have nonsense to add wich to me is accurate.
    Over populated is an issue but an advantage as well. At this point instead of competing on who is richer or smarter, maybe we should be realistic. One the Congress logo Eugenics was a way to implicate Involuntary Sterilizarion, while in gods bible states ā€œLet them multiplyā€. ( not that I red the Bible or studied anything of Medicine) The best teacher is a great mother and Mother Nature teaches us by our senses and critical thinking. The science catagory knows we can’t survive normally in other planets. Yet we find better way to make life easier because the laws and code of conduct has created this way of controlling the people with their own benefit. Light, heat, shelter, school,work etc. the worl was made to give us resources our choice were given to see if we have good judgement. Confusion is key to wrong doing. Knowledge is the cure. If we were all educated to protect the Earth we wouldn’t be fighting for clicks, as in country and all, if we all spoke one language had one believe and know and act upon what’s right millions of people could survive to protect the earth.

    Unprofessionally writing here.

    We need the animals we need the water we need the plants we have to let go of the money and unnecessary product made by product that are none recyclable.
    God mad rules already there should be no other than that , I don’t think he ever approved for it, yet he sits in the side lines because we only learn from our mistakes. That’s how we succeed.

    Thank you for your time.

  14. I'm not saying that we need to take extreme measures by any means, but we do need to pay attention to this issue. Animals in nature reach their carrying capacity all the time. If we look at deer they sometimes reach the limit of what the environment can sustain. Then nature takes its course such as disease or they outgrow their food source. The population is expected to double again in the next 50 years. Its just a matter of sustainability humans are responsible for many more species extinctions every year and we rely on certain animals and plants for survival ( such as honey bees for example which are also declining because of a disease that the bees get, so its not our fault necessarily). To me its more of a consumption issue. We can probably sustain more people if some countries will stop consuming so much. In my country (United States) we waste over 50 percent of our food and consume more than any other country. Climate change will be another issue. Whether you believe that its naturally happening or not ( I believe its naturally occurring, the earth has changed its environments for billions of years, but I believe that humans are speeding up the process by emitting greenhouse gasses).I do not hate humans by any means, we have achieved so much as a species and have solved many problems throughout human history. We are facing a problem of sustainability and climate change as of now and although it may be a big issue. I have faith in humanity that we can work though this. That's why I joined this field to help eradicate some of the issues concerning the environment today and hope to enrich the future so that humans can inhabit this planet for future generations. Just letting everyone know I'm not trying to go against anyone's beliefs or customs. I am just presenting some things to you all based on the research I have done.

  15. The entire earths population can fit in the State of Florida and still live comfortably. lol. The whole premise that the population is exploding and theres no room is nothing more than the Elite Scum who are not worried about that but are in fact worried that the 99% will wake up and hang them by their balls or tits. So sick and tired of fools listening or regurgitating this lie. No one on this earth should go without food. Also another lie is that humans were around for millions of years on this earth. If we were here for that long, do you really think there would be only 6.8 billion people on this planet? Until you all understand these facts, you will continue to be led astray by these satanists whose sole purpose is to deceive you that there is no GOD. Use you common sense and dont be a recording of what you hear.

  18. WOW, All of you have a manacle of opinion. Great stuff and, well said (for most).
    But, I must say! For those that are GOD inspired. The Bible was not written by GOD, it was written by man, wither you like it or not.
    Don't get me wrong I was raised in Religion and, Baptist! At a young age. However I have learned that a miracle has the same chances as winning the Lottery. That Race is not coming to save you, though it may come and destroy you for stupidity. As has happened in the past. According to the good book. Yet still written by man. GOD may have said "Be fruitful and multiply" but, yet not only did "PAUL & JESUS" afterwards. Preach CELABCEY to stop the practice. In the New Testament. Why do Christians continue with there sinning ways. In multiples! This can be considered an abomination to the word of his way. If you really want to know, I conceive that if you don't have kids, you get to come back and, re-spawn in order too change the World. The way it was meant to be. In the order that is pre ordained. I see this because, Time can be manipulated as Einstein suggested. We may very well be locked in a loop that will continue until we get it right. Be good and good too others! My fellow Humans.

  19. I'm doing a paper on basic human needs. This video focusses primarily on cities and towns being over populated, so maybe its time that people start moving out of the city into the wilderness where they can grow their own crops and raise their own farm animals. Canada has a massive Northern landscape that is barely touched. Every US state has massive amounts of land with not a person or road or lake or tree or farm or anything else on it. I was looking at google earth today overtop of Africa. In the South Africa the population is 52.98 million and the land mass is 1.22 million square kilometers, but only a fraction is used by cities, towns and villages and still only a fraction of that land is used up by farms. Why can't we develop outsite the cities. Why can't families grow enough food on their own lands. Give everyone a pocket of land instead the government, private business or others hoarding it for themselves. In Papua New Guinea a drought wiped out all crops and many people died of starvation and thirst. Why? People were eating clay to retrieve water...why can't they drink they water coming down the river? People need to use the resources they have right in front of their faces, but how can they if the developed world refuses to pass along the information. There is ample evidence showing transfer of information in the ancient world. But at some point between the ancient world and the developed world, the information stopped transfering and its primarily because nations received freely and then decided to sell it instead of give it freely! Basic needs of a developing nation as described by the United Nations is the ability to pay for food shelter and clothing, but this is flawed. Instead basic needs should be: the ability to aquire new knowledge, new abilities and new processes through free information transfer. So instead of the developed world stipping third world countries of all its natural resources, they should be focussing more on showing the third world country how to access it themselves so that third world country doesn't have to borrow from the developed country to feed its citizens. In 3000BC copper was mined in Romania. It took, just 200 years for the technology and information for mining copper to travel 3000 miles. But for that same technology to reach Papua New Guinea, it took 5000 years. Why? Its because the information did not transfer.

  20. :-) I did a calculation and we can go up to 200( two hundred) billion on our Earth. Earth surface is 510.1 million km² and for a family of 5 members I said to have 1800 m2(= A big house 10x10m, a big courtyard 20x50m, surrounded by streets/space all around).

    We have to admit that we have A LOT of resources on Earth which we don't use.

    What resources we use we overproduce then we don't manage well: So some people throw food and resources away and some people are missing them.

    The conclusion: We have a lot of room on Earth, food and energy for everybody. We have to use our brains to find solutions and our heart to worship God our GOOD Creator.

    Be blessed with no worries!

  22. planet earth will heal itself, if we cross the limit there will be, on a regular basis new deseases are being launched like new clothes & i don't know why do you think USA is the only nation, human population is supposed to cross 10 billion in a very short time (US contains only 4.5-5% of world population) & according to my calculation no nation lasts strong more than 500 yrs in every millennium whorld dramatically changes twice, so not sure USA will last that long, every kingdom fall one day. if we are supposed to be dead let us, mother earth will last longer without US (F****** HUMAN including me )

  23. I agree, for the most part. It is terrible that we alone have caused so much destruction, however I wouldn't say we are a threat to this planet. The amazing thing about earth is it's ability to heal itself. When we overstep our existence, this planet will do what it needs to to knock us back down. Or off completely. I have a strong feeling there will be earth after humans. Unfortunately we're not helping out cause.

  25. Another thing to consider is what do you do if you ever had a hurricane and an electrical storm on a REALLY big scale... so many things would be affected, its not like the governments can close the doors and let it pass or go out and do anything about it. They would see it coming, but we've also seen really horrible natural disasters. we even explain one as the extinction of dinosaurs. If ppl dont kill ppl (war,disease,famine), what happens when a really big cloud shows up and happens to fry a bunch of things? basically what happened with the world trade center. not the controversy, I mean that it was part of world finances being offset. only so much they can do with natures forces. A comet takes out hoover dam... all that water is going somewhere.. if they have emergencey drains or not. they might have a way to deal with that as opposed to a catostrophic electrical storm that would fry every computer in the US. sattellites are dead cause theres no access from computer and everything run by computer is "dead". That would set alot of the population back to dealing with how does bread get to grocer if the grocer cant get any shipments?
