How many people can live on planet earth? - BBC Horizon (HD)

[longyearbyen17]

what he say at 11:05 unpressidentive? i don get it

[dhsredhead]

I'm going to have to stop watching this. I'm all about conservation, I believe we are harming the planet. However, population isn't the only problem. It's that those of us in the Western world have been using way more then we need to. This pessimistic viewpoint doesn't offer many solutions to solve the crisis of what to do with the people we already have here.

[nicoleiscoolrawwwwrr]

So many more people need to see this.

[falutak]

I AM RELIGION, YOUR ARGUMENT IS INVALID!

[webdubai]

How many children you want ?

[philthy122]

Unfortunately in the use of these types of birth control and their environmental impact weren't addressed. These cause a build up of oestrogen in the environment and reduce the sperm counts in all animals that ingest affected water supplies. The only real birth control that is has no environmental impact is medical sterilisation.

[Z0mfgN00b]

Killing Kony sure wont help this problem

[ohnoesfedzilla]

population control

[troglodyte2084]

Soylent green

[peterv1988]

There is a famous saying from Ghandi:

"Earth provides enough to satisfy every man's need, but not every man's greed"

[AGTothful]

...and why shall the USA have a population growth whereas Canada wont?

[AGTothful]

why will the UK have a growth in population whereas Germany won´t? both cultures are very similar.... so? why? (is it because so many hindu and muslims live there?)

[BUDGRIGA]

we need to spread out into space to survive

[mephisto88x]

@BUDGRIGA and what corrupt other place in space

humans are too destructive, we'll just over populate where we go

we must have a rule of only 1 kid per couple , need to more responsible

on things we do.

[EgaoNoGenki]

At about 1:39 - double the amount of food... Well, that's what "vertical farms" are for. You can search for that term here.

[not2b8b4u]

Stupid is as stupid does. Just a few hours of thermonuclear war can run those numbers down real hard.'

[darthvader5300]

@not2b8b4u You have no faith in humanity's humanity in nurturing the value of human life. Man was created by this planet for a purpose. Earth is the cradle of humanity but humanity cannot live in the cradle forever. Thermonuclear war? We're prepared for that for decades, we can rebuild modern human civilization with 3 to 5 years after peace has been established. I have seen the horrors of war. you probably have not seen it, when one has experience a war, no one wants it except when force into it

[darthvader5300]

Pollution? Pollution is just a form of wasted raw material. For example: a copper mine mining copper used to pollute it's surroundings wt sulfurous pollutants killing the environment. Now that the copper content is to uneconomically low to mine it turned to mine the economically minable sulphur! What is needed is a multi-elemental mining industry extracting everything from the ores leaving only non-toxic pure sand and an industrial eco-system w/c we can do now!

[not2b8b4u]

@darthvader5300

Yes. like non-toxic building blocks. but so many efforts have blow up right in our faces with mine tailings and land fill, and fly ash all having unknown but then persistant toxics in them creating all sorts of problems.

[darthvader5300]

@not2b8b4u Mine tailings and fly ash has been successfully and economically immobilized by geopolymers and ceramicretes. The only reason why they're not being used is because law enforcement is either lax or non-existent.

[darthvader5300]

How many people can live on Earth? Add vertical farming, vertical agriculture, yeast farms, algae farms, aquaculture to the first statement. Then you many add an another 200 to 300 billion people. People well versed in engineering technologies concerning living machines, life-support systems, etc will know exactly what I am saying. Those not well versed in such fields will oppose me. May I also add underground cities. Mismanagement creates artificial shortages (bad politics included).

[darthvader5300]

How many people can live on Earth? Let's sum it up. Rock dust powder remineralization, terra-preta charcoal powder, mittleider & bengal hydroponics, passive aquaponics, recycling living machines biospheric life-support environmental systems, thermal depolymerization, Solar Aquatics, anaerobic diatomaceous earth combined wt hydroponics recycling, engineered marsh, artificial pre-flood atmosphere, Harrison Brown process, BREST nuclear power, proper education, etc. 200 to 300 billion people.

[not2b8b4u]

@darthvader5300

Those ideas have merit, leaving the planet has none.

[darthvader5300]

@not2b8b4u These ideas has been in existence since the 60s and 70s, it is their lack of application which is the problem, mostly political in nature. Professor John Todd's Living Machines, Solar Aquacells, Muskegon project, etc are already in place but not applied extensively because mainly of political reasons and their economics has already been solved.

[MtothamuthafuckinK]

And if we run out of food on earth then millions will die that is nature and the earth will replenish it self. ANd the people who survive will learn from our greedy mistakes. THat is the only way man learns through pain.

[MtothamuthafuckinK]

I dont have kids but i have flown all around the world like this guy and let me tell you there are so many places in this world where you can fly over jungle for 7 hrs and not see one light. There is plent here on earth its just that those whose are in control are not good stewarts of the land. Profit is the problem. WHy are they trying to pass more and more laws to stop people from growing there on food tell me that. Profit is the problem

[wwe3466]

@MtothamuthafuckinK no it isn't

[xjohannes98]

people need to stop being selfish and getting pregnant cuz at some point we are going to get over populated

[darthvader5300]

@xjohannes98 We live not on one planet. We live in a solar system of 9 major planets, many moons, hundreds of thousands of asteroids. With technology humanity can re-create engineered self-sustaining living machines powered life-support environmental systems powered by nuclear fission and fusion and solar in space. Earth is the cradle of humanity but humanity cannot live in the cradle forever.

[not2b8b4u]

@darthvader5300

Energy costs more than available on the planet. Your idea is rejected.

[darthvader5300]

@not2b8b4u It is apparent that you have not heard of our almost 400 abiotic oil and gas wells nor our Russian BREST reactor power plants that can breed it's own replacement fuel and consumes it's own nuclear wastes and capable of being redesigned to breed more nuclear fuel than it needs.

[GZAthaGeniuz]

This documentary is not relevant at all, of all the so-called problems we would have with overpopulation we can solve 90% of them today.

There is no shortage of food/drinkable water/engergy or housing, there is just poor management by the governments and an endless competition for money.

[GavSalkeld]

Thank you for posting this. A Brit in the USA.

[nephildevil]

9 billion in 2050 pfff a couple of dozen tiny new wars isnt going to do it i suppose, we need more efficient methods of extermination

[intermender]

This is easy. Humans overproduce like any animal because of insecurity. Insecurity because of lack of simple basic needs. Lack of simple basic needs because unfair distribution of wealth and power.

[fernibear]

39:30 Tell you why the africans and indians dont use much of their global hectares its cuz they all come to the UK and thats why we have to use so much, then they have all their kids over here meaning more strain on the British, with the governement being stupid enough to give them all these benifits its causing more to come here. So the solution, vote BNP.

[karth17]

@fernibear Plz konw the facts before commenting.

UK population demographics - Indian 1.6%, pakis 1.4 %, africans 0.8 %. please stop blaming 'outsiders'. americans and europians typicaly consume more. thats a fact. accept it.

Regards from india

[kingj282]

40:00 .... fuck

[phillips78]

More on this topic at "One Planet, One Child" and "Overconsumpulation".

[thirstofink]

The thing is, we dont even need to do anything just have 1 kid, then its ok...population will reduce if we all just have 1 kid, just dont have more than 2....... meanwhile familys in the US is having 14 kids 15 kids ...... it seems like a anomaly in the correlation about access to education and birth rate

[thirstofink]

I have to disagree to the education will automatically cause drop in birth rate... US and UK has highest teen birth rate in Europe and in the world...... they have one of the best education system in the world

[starsbydaylight]

@thirstofink The birth rate of the African American children in the US is secretly stopped there by means of forced sterilization through the 'family planning' clinics, these clinics appearing world wide in the colored peoples suburbs! US white population, UK white population have the highest birth rate because the health system readily accommodates the abortion of colored women's babies, then forces the colored mothers to be sterilized, or sterilizes the women anyway ... ...

[TheWizardWeiss]

And I don't understand why people hate LBGT people , at least we don't reproduce , we adopt your children

[fernibear]

@TheWizardWeiss Exactly, good point.Tho i will be having children with my partner were likely to only have one or two because its harder for 2 women to have children, it has to be planned there is no mistake children and it can cost alot to do it.

[lifeisgood902]

@TheWizardWeiss i dont hate

[qwertyui90qwertyui90]

How about we just have a 1 child policy accross the world ?

[TheWizardWeiss]

@qwertyui90qwertyui90 Still the number of people would increase , at least half of the world population shouldn't reproduce I mean half of the couples , But even if that policy was adopted things wouldn't work out as expected mainly in africa , I guess we will still let it for the future because you know humans only do something when it's too late

[darthvader5300]

@TheWizardWeiss No one has any right to make those God like decisions for other people. If you want immortality then all you have to do is look at the cradle from which you came from and from which (hopefully and pro-natally) your children will come from and in their eyes you will see the hope of humanity if given a full chance to fullfill that hope. Man is not plastic, he is infinitely creative. We do not live in one planet but in a solar system full of resources just waiting for us.

[TheWizardWeiss]

@darthvader5300 Sorry I don't discuss religious stuff have a nice day

[darthvader5300]

@TheWizardWeiss Thanks but I want to clarify one thing. It is not a religious statement, it is a historical philosophical truth based on a truthful and honest statement from an unnamed scientist who said it during the heyday of the space age of the 60s and 70s and his statement is "Earth is the cradle of humanity but humanity cannot live in the cradle forever".

[TheWizardWeiss]

@darthvader5300 Oh , ok

[george85P]

We are so fucked...only us can do something about it ...but seems we dont have time for save the planet ...instead we have time to distroit...

[sNovaka]

this is all nonsence... ..Attenborough took credits for supporting eugenica.

[starsbydaylight]

@sNovaka Yes ... Attenborough is brainwashed, because if people would stop taking part in feeding themselves through the illness and world wide famine causing, perfidiously brutal meat-industry, there would be enough food to feed us all. People don't know about this, can not be blamed for not knowing about valid agricultural systems, because our education is terribly flawed. We are fooled, we don't know abt valid, sustainable agriculture. All we know is abt making Big Money for 'them'.

[jimbocidman]

To sum up this video in one short phrase: we're fucked!

[TheAdamTucker]

Im confused. The world is heading for a population crisis....my understanding was that we already were in one, and for quite some time now.

[Skywalker91]

One of the many reasons I won't ever reproduce...

[ColdByrdz]

@Skywalker91 Ahahah...meanwhile in Africa =p

[kinkypinky6969]

I think it's nuts that we have water in our taps but yet we pay money for bottle water ? Blue gold

[TheSeeker1965]

I must admit. agent smith's explanation about the human inhabitance on this planet to morpheous in "the matrix" movie was spot on. damn shame reeves character in " the day the earth stood still" didn't follow thru on a well planned and beneficial mission, save the earth and everything else , cept it's only destroyers.( guess who)?, and why i was disgusted with the sorry conclusion. This documentary was very good. It opened my eyes,. we all need to do something to bring about positive changes.

[Pinkchyo]

we are the greatests paracites ever!!

[glowandnoise]

Thumbs up to the indian guy in the pink shirt. Love his positive attitude...inspiring.

[RaulMeatFactorys]

Humans are the worst of viruses, the worst threat to the planet........ Thanks for upload

[anthonychinnis]

or 3 to 5 billion maxium

[anthonychinnis]

so what you are saying is that the earth really can have a maxium human population of 3 billion people so that we all can live comfortablely.

[anthonychinnis]

what's the birth rate versus the death rate? for every human that is born what is the number of deaths? is it the same or different by how much?

[BloodyLisBeth]

I have the impression that most of our fellow humans are not so far from animality. when you haven't food for 2 kids,what can drive you to go further?

not speaking about clothes,school and other"luxuries"...

[U5K0]

I'm missing the part where this is our problem. The west can easily accomodate the projected extra numbers. In fact, Europe in general has a nearly stable population.

As for others; they wanted their independance, now that they have it, their problems are their own. The choice of solving them or not is theirs alone.

[kirriereoch]

@U5K0 I guess it´s the fact that Europe imports a large proportion of its food,timber,oil etc from the rest of the world.If,as seems the trend,the world is becoming "more democratic" then it´s a given that new democracies&their elected parties will look to the demands of their own populations first & so reduce or stop exports, or export to the new growth markets outside of Europe, e.g.China(currently buying up huge tracts of Europe & its companies) & India,where the "new" money &growth now are.

[trevorwoods]

@U5K0 technically you might be right, reality is different though...at least for now THE earth is a closed system where we as humans can only "break stuff" instead of making the system better...and if you leave other people to solve problems in this closed system it will not happen, people are like that.

Regretfully this is one topic where we all have to make it our problem to make this a better place, even if it is out of selfish reasons...

[HenryDavidT]

2 sets of problems: population growth & over consumption.

Over consumption is Westerners problem. E.g., at 4% of the world's people, the USA consumes 25% of the world's resource.

But population growth can be easily slowed by MERELY giving good education to women.

Over consumption, unfortunately, can't be dealt with as easily, regardless whether a person is rich or poor, educated or uneducated. In fact, the more educated & richer a person is, the more resources he/she consumes & wastes.

[kirriereoch]

@HenryDavidT That´s a nice summing up of the population conundrum. Education and access to adequate health care means lower birthrates but also increased consumption, or at least awareness of more comfortable lifestyles that exist. It also leads to political and environmental awareness, which can also have positive results (or negative depending on the country/region etc).

[starsbydaylight]

@HenryDavidT In this patriarchal ridden world a woman has no voice. In so called third world countries, if her man wants her ... that's it. She'll have to be pregnant again. Women do not want to be pregnant all of the time. We live in a man's world. Women unknowingly suffer intensely as a result of being utterly brainwashed by Patriarchy into thinking that they have but one 'great' task: producing kids. 'Giving good education to women' ... you must be dreaming, must be a man.

[vmgqie]

don't help developing countries let'em sink or swim on there own

[kirriereoch]

@vmgqie If a developing country sinks then where do you think the refugees from conflict, drought, famine and economic crisis will want to go? It´s hard enough to stop mass immigration now in Europe. Imagine that, ten or one hundred fold?

[Sithlug]

thanks! all should watch and all should think about the big picture!

David is a champ which i lived his life!

[Sithlug]

@Sithlug wish even..

[eblackrose00]

so the americans and britains are eating too much?

[brugey34]

@eblackrose00 No they spoil to much.
