SUBSCRIBE! ►► http://bit.ly/iotbs_sub Is overpopulation real? Is Earth filling up with too many humans? How many people can Earth hold, anyway? As our species approaches 8 billion, human overpopulation is a major concern for many people. How can we reduce poverty and our impact on the environment? Do we need a forced one-child policy or something? Maybe not, because when we look at the science and history, populations seem to control themselves. This week we look at all these questions and more.

I wonder if we could get all 7.6 billion people on Earth to watch this video? It's worth a try… Leave a comment and let us know what you thought of this week's video! Got any ideas or big questions you want answered? Find us on Twitter

Here's my idea. End all humanitarian and peacekeeping missions to the Third World and let the subsequent outbreak of famine, disease, and endemic warfare manage the population, saving the First World countless man hours and untold billions in aid spending.

just because people crowd in the cities, it doesn't mean that earth is overpopulated. Terra can sustain at least 1000 billions people, but with some tech advancements for food production, air filtering and waste conversion.

The demographic transition model shows that human population will equalize around 10 Billion. Even the United Nations has stated emphatically that there will never be a 12 Billionth person no matter what. Combine that with our increasing technology and adaptations and we will be just fine.

Lets take a lesson from Japan. Lower population growth combined with lower elderly mortality rates is not good. In most developed countries, there is starting to be less poor people to support to elderly.
Calico Jack (20 days ago)
All videos like this do is convince nerdy intelligent people not to have kids. Overpopulation wouldn't be a problem if we had an abundance of smart people, the problem is the number of low IQ people breeding like rabbits in Africa and India. A video like this does nothing but harm. Modern Whites are naive fools.

Well, those statistics actually overestimaye fertility rates. In fact, it made a systematic error. In upper nations it's more of 1.7 per woman. Furthermore colonisation of space is the solution. Maybe it's there already, yet (nearly) no one knows about it. What is it called?

Too much Liberal Left wing talking. Third world religious shitholes keep breeding. Imaginary border lines? The population graph has 2100 actually listed as 2000. And Europe and North America EARN their advancements. Everyone want to come to these place WITHOUT the sacrifices that were made in the past. “Education of women” another liberal word speak. Everyone wants Right but looks over the Responsibilities. Global Warming is not a fact. It’s a theory so stop talking about it like it’s factual. One volcanoes- not man made- can up load tons of Carbon. Btw the Earth is the greenist it’s ever been. Plants feed on Carbon. Close the borders. Share technology. But OVERPOPULATION IS THE CRISIS! You don’t limited your population you don’t get the benefits of advancement of your “imaginary borders.”
Well Folks (23 days ago)
field north Now I don't disagree 100% with your statement, but climate change is a fact. Maybe not every single part of it, but chemically speaking: the ozone layer (O3) converts to oxigen (O2) and back to ozone, this happens naturally through the sun rays and thus forms a chemical equivalent. However, this balance can be tilted by using a catalysts(ODS) such as chlorin(Cl) which helps the (O3) to convert to (O2), but not the other way around. With that the amount of ozone depletes and dangerous UV rays are enabled to get to the surface of the earth, where we live.

The first world is obese and we throw out a third of all food from the farm. As soon as that gets expensive things will adjust. Plus huge parts of the planet are dessert and a bit of nuclear power and desalination could change that.

Neptune Neptune (30 days ago)
The thing is that most arguments that claim that "Earth can't hold this number of people" are pessimistic and don't seem to know or care about the idea of human progression. What needs to happen is for food to be equally distributed and the production of resources in environments beyond Earth (the Moon and Mars, for example). We could also promote the production of meat by way of stem cells rather than factory farming and then decrease the amount of meat consumption to a smaller portion of resources consumed. We _could_ also find a way to get farm-to-table calorie preservation much more efficient, but "lab meat" would be the way to go.

we are twice as over populated as we should be already, the whole world should be using japan as an example
Hjernespreng (28 days ago)
No we shouldn't. Japan is having a CRISIS of demographics, and the reason they are so rapidly having fewer kids is because the societal expectations set on Japanese youth are so enormous that even people that would want to have a family don't start one, because their work life is HELL.

Zezolia The Queing of mortals (1 month ago)
This video is quite interesting because in school they always taught us that we have the opposite population problem. They do this because in some European countries they are starting to have a reverse age pyramid because people don't have as much babies and elders live longer. In Spain they are warning us about the problems that this will cause us in the future, but they are not giving any racional solutions. They acknowledge that immigration is one of the reasons why there is still some balance on the pyramid, but when given the opportunity they prefer to scare the teenagers telling them how they should have babies rather than let refugees inside the country.
Rhett A (1 month ago)
Thank you for this video. I think many DO NOT think about overpopulation - religious and uneducated peoples tend to scoff at it or take offense to the suggestion that we should be socially responsible where having children is concerned. Message delivery style is often as important as the message itself - this is likely one of those cases.

no, we will never go to live on mars, unless we find some like rare minerals there that we can use for something really important like finding fossil fuels deep underground, as far as moving to mars for over population adverting...very unlikely. It would be much cheaper and safer to figure out how to cultivate and inhabit lands on earth that are already unused.

According to the economist-Simon Kuznets, the population increases the consumption of environmental resources with the advancement of civilization, but it is not an exponential process. The consumption of the environment increases only up to a certain moment when the environment becomes a value in itself instead of only a factor enabling development. After reaching this point, the resource consumption decreases. The curve in the shape of an inverted "U" is called the Environmental Kuznets Curve (EKC). The historical values ​​of sulfur dioxide emissions, for example, are in line with the course of the Kuzniec curve. According to the physicist - David Deutsch - the only "resource" that is needed for humanity to survive in the long term is intelligence and knowledge, while the availability of natural resources depends solely on the finiteness of the universe. Deutsch notes that since extinction of species is a phenomenon that occurs all the time, the only survival option for humanity is the use of the only feature that distinguishes it from other species - or intelligence. The solution is not limiting the level of industrial production, postulated by movements of sustainable development (eg the Kyoto Protocol for global warming), because it will degrade everything that we define as the achievements of civilization and will be a catastrophe in itself. In particular, it will make it impossible to stop the potentially negative effects of global warming. -Hans Rosling- believes that population growth is not a threat but a chance for humanity. Rosling, studying demographic and social changes in the history of mankind, shows that periods of rapid, exponential population growth are short-lived (on a historical scale) and slow down after a given population reaches a certain level of civilization (which is observed in developed societies). Rosling also indicates that during the twentieth century, the quality of life of almost all populations in the world has improved significantly, not decreased, while the fertility rate decreased, which in 1963 was on average 5 children per mother, and in 2012 only 2.5 children per mother. Rosling also conducted knowledge on overpopulation - in the United Kingdom, the majority of respondents, including people with higher education, reported drastically inflated fertility rates, which Rosling says indicates that the problem of overpopulation is mainly the problem of perception in developed Western societies, not a real problem in developing countries, such as Bangladesh (fertility at 2.5). According to Rosling, this fall in fertility, with the simultaneous extension of life, is also one of the most important demographic changes in the history of mankind.

There’s no overpopulation. If you get ten miles outside of a city you could easily see that. Every human being on earth could sit comfortably inside a cube one mile on a side. It’s just an asinine, anti-human take.
mosquitobight (1 month ago)
Overpopulation has nothing to do with empty space. It's about food and other resources. If you get ten miles outside of a city, you see the land being fully used for agriculture, if it's fertile. We each have a few acres of virtual farmland somewhere with our name on it. You need your share of the farmland more than you need your own home.

Hjernespreng (28 days ago)
What about it? It DOES. More vaccines means more children surviving to adulthood, which means less need for more children in order to guarantee that at least some survive to adulthood. You'll get an INITIAL population boom, but then it shortly starts to decline, JUST LIKE IT DID IN THE WEST. Did you even watch the video?

Easy. Overpopulation is when mass migration of population occurs. LOOK AROUND YOU, YOU DOPE! (the guy in the video) There is starvation all over the world because the populations there are useless eaters that can't support themselves. Gates and his ilk figure that taxing the hell out of the rest of us will solve this. Bring everyone (except rich him of course!) down to some grovelling same low level so mass migration will not happen. No reason to flood into the USA because it is then also a S.H. (see Donald's excellent comment if you can't guess what the letters s.h. mean)
