Malay Agarwal : The simple answer is this: If we go on living the way we do, we probably aren't going to get to 10 billion.

Olive Kelly : 45 yrs. female and having no kids my greatest contribution to society.

DAMfoxygrampa : We somehow hittin 10 billion but I can't get a text back

TerielAtmano : People would protest and share knowledge if they saw the problems in this video as greater than their own personal troubles. No one has time to go to the streets to fight for nuclear energy when they're struggling for enough money, a loving partner, good friends, having time to relax, being skilled at something, getting rid of personal addictions... Until we get better at solving personal problems at a global scale, we won't care about the bigger picture. Universal basic income seems like a good start to free up some personal energy to devote to bigger matters. This might not work either, as it seems like we'll just keep comparing ourselves to each other and finding new personal worries to spend our energy on. Maybe we should study the mindsets of people who made change on a greater scale, and try to create conditions that foster those mindsets on a massive scale.

Teacher Advice Hanoi : Perhaps y'all should...umm...stop breeding

Anna-Maree Castillo : ALL civilizations rise & fall over time. Our civilization is no different. 😉

fxc2 : The cynic in me says that a lot of people are going to be left to die without basic resources while in the wealthy countries almost nothing will really change...

Alan C : Birth control, one child policy, make the human population growth negative for decades and decades to some sweet spot. Plant trees and eat more vegan food etc.

morninboy : We wont survive period. When a parasite consumes its host with no other available it is the end. Say goodbye to most life forms thanks to humanity. We will prove ourselves to be one of the least successful species in earths history. Two hundred thousand years seems to be our limit the way things are going. The dinosaurs got a hundred million

ak p : Birth control for everyone, max 2 kids pr family.

souptroophat Esplin : Thanos wants to know your location

Fátima Reyes : To me, the solution has always been obvious: educate people. It has been shown that the more educated people are, the less kids they have; the more educated they are, the more money they make and the more aware they are of human problems, and therefore the more willing they are to help solve them.

ben s : It's telling in the part where he says, "We think we're special, but it's much worse than that", then everybody laughs. You'd think a statement like that would silence everyone, but the irony is we do think we're so special that our individual preservation will always come before a globalised effort to make the changes we need.

TheAstrius : The smartest 2 billion will kill the other 8 billion is how, survival of the fittest.

SuicideBunny6 : Yer a wizard, Harry!

Marshall Banana : I work in a grocery store and every single day, I throw away hundreds of pounds of perfectly good food. My last job was a restaurant job, same exact deal. Most of the food that came to us goes straight into the trash eventually. And yet all I hear about are people saying we don't have enough food to feed 10 billion, that's bullshit. We have so much food we throw away enough to feed 10 billion!

Quahntasy - Animating Universe : All I am waiting for is *Thanos* Admit it deep in our hearts we know he is not the real villain.

Matt : People dont have large families any more in the developed world. Condoms are cheap. Education is abundant. You people will worry about anything. Idiots. The population won't increase exponentially. Countries like Japan are running out of young people. The developed world has gone mad and abandoned the idea of the family. Not that human beings were very sane to begin with. We follow precedent at every turn, the amount that thinking for ourselves matters is nilch. The tide of the masses carry us all forward. Nobody is free.

Terncote : To the people blithely claiming that the answer is to colonise space. Please give your heads a shake. Do you have any idea how much more stress on resources and the environment it would cause to physically relocate enough people to relieve population pressure on earth? Presently it costs over $20,000 USD to lift ONE KILOGRAM of payload into orbit. That's over $1.6 million just to get a naked person off planet. Now compare that to the price of a condom or birth control pills. Moving off planet won't solve the issue of too many humans demanding too much from the Earth.

Susan Cheung : Don't worry,.....nuclear weapons can solve the population problem......

Vagitarian : That's why me and my lady have a mirenna! We would have loved to be parents in a normal world! But not this cruel, evilly overpopulated world where nowadays everyone just hates each other! Mankind has gone past the point of no return! Having children at this point is the most cruel and selfish act you can perform! The baby boomers have destroyed the world! We want to adopt and try and make a difference in someone's life that is already here! Don't give in to the hatred, exhaustion, fear, and endless frustration of the people around you in this dying world! Be a light of love and kindness in this dark and terrible world! Don't let it take your kindness and generosity!

Toby Robinson : My family stoped using plastic bags, lowered water and power usage, moved to a vegetarian diet and each day we do a little more. We take small steps and will keep making them. We all need to care less about our selfs and more about what’s around us.

kokoleka808 : The richest 10% use 50% of the world's resources. By making it virtually impossible to be wealthy via a progressive tax system and this would be one of the most important steps to making the world sustainable. Conversely, allowing the rich to get richer by allowing their tax avoidance schemes is not at all conducive to sustainability.

kremit the frog : *_Thanos will save us_*

Armaan Panda : Humans👫 are not endangered species, so it is sensible to stop producing Tell Tigers🐅 to produce more because they are endangered

Sean Uptown : Less procreation. Humanity should focus on 4 billion by 2118, 3 billion by 2150. Quality is better than quantity, the first global singularity should be the plan for reduced procreation world wide.

Hippo : WE WILL EAT THE FRIGGIN BABIES.

rodenrren2 : Is corruption and inequality in Tokyo really that low??

Sank E : Procrastination will end the human dynasty .

lello333 : one of the best guy in TED.. i enjoyed the presentation, hope someone had learn

vj lockett : Tired of these scare mongering idiots. People said the exact same stuff in the 60s about how by the year 2000 we will have 7 billion+ and be living in filth as we fight for resources. These idiots always fail to understand that history very clearly shows us that the more people we have the richer we all are. People on average create more than they consume in the economy, so the more people the bigger the surplus of resources. You losers can tell yourself whatever you want to cope with being so low on social ladder kids were beyond your prospects.

DAV : Simple distribute them equally to all countries in the world. Leftest globalist would love that.

Timo Kotipelto : Just embrace capitalism and stop trying to control de lives of other people.

Elise : Stabilizing and decreasing the population, with a worldwide two-child policy. + free birth control for everyone :) And supporting a plant-based diet.

Jason Vectrex : We will just start wars and kill each other eventually on a grand scale like the old days to free up resources and land, and keep the population down.

Iancreed8592 : Fact is...most the surplus population is 3rd world. Why are we trying to aid these countries and prop them up? Its like patching a crumbling foundation with bandaids. 3rd world countries need to be left to take care of themselves and let nature take care of population...sound 'immoral' to you? Not as immoral as bringing more lives into a world of misery...and for what?

IYSISNASIR : *THIS MAN IS CORRECT, RID THE EARTH OF THE DEVIL CAUCASIAN SWINE RACE- WHO HAS REEKED HAVOC STARTED ALL WARS & POLLUTED THE EARTH.(Except for Becky She can Suck the Leather off a basket ball !)*

alex Debroux : The only solution would be to decrease the population and keep it fixed at a certain number (8 billion for example). If people don't want to listen, we'll need to kill their babies and feast on their tiny corpses to teach the parents a valuable lesson.

Paul Googol : if we can reach 10.000.000.000, can everybody get an achievement badge?

Fleck Smugbrother : We are corrupted by greed, self interest, a natural human instinct. In the long run, it spells our demise....

Sal Lami : The wizards and prophets may have different philosophies but they are both supporting the idea of continuous population growth which is unsustainable. The only solution is to Reduce or at least freeze the population growth. Think about it, if there were only a billion people on the planet how much less food, water, amenities would be needed? We'd contain the break out and save humanity instead of counting on reactive ideas/tech to save us.

HiBrian : "except for possibly tokyo"

Abdullah Khalid : I now realize that actual villain was Thor and not the other way around.

David Sanchez : No, we are not special, essentially because we act and react for the same mechanism that simpler way of life does. We are just more complex, and with complexity comes both problem and the solutions of those problems. Society is the continuation of the Nature, and for some hundreds of years there will be an overlap between Nature and Society. Eventually, the forces of the Nature will have less and less power and Humanity, will be less and less "Nature" a more a product of our own Intelligence.   Now, this is not going to happen in this Century, meanwhile is developed a new kind of Human, we must survive as specie... How? Keeping Science and Technology working together and changing our Economic systems. All those limitations the speaker is telling us depend in reality , of our Economic system. Realizing this will give enough time and resources for the next Human phase. In my opinion, in the next 30-40 years, the Human Society will change all the predominant ideas about Economy, Richness, Efficiency, Labor, Social class and roles... and will open the door for the Capitalism evolution to a more balanced Economic System (we must, if we want to survive)

Jack Scott : Can I just point out that population growth in Europe and much of the West is remarkably low, and is in some European countries negative. Population growth occurs much more significantly in the 3rd World.

meledous meledous : how about we teach each other how to grow plants and vegetables. How about an option, from those that lead us, to give everyone planter boxes to grow our own food. It will create a new industry and also leave the farming industry to grow, because professionals always do better. We can't sit on this doomsday of having babies. The answer is renewable growth, which we can do with a little bit of help from the sun and some rain water.

ano nymous : I have no clue what his point was. Exceptionalism despite all counterarguments? Co-operation between "wizards & prophets" is just delaying the cataclysm not a solution. There are only two relevant paths: human population planning or doom. The first would mean losing the right to reproduce for many and euthanasia being globally accepted. I'm a pessimist. There is no way we can prevent this from ending badly for our species.

Urelasir : Its obvious, the rich few will have everything and protection while the poor die of hunger. Thats how humanity works.

Ryan Voll : If humans weren't so greedy, we'd have no problem surviving with 10 billion people, and we'd be able to fix the climate problems. But our politicians only care about making themselves money, by helping their friends make more profit, which they have shares in those companies.

innerrevolution1 : Some good points like: work together, but he missed out on the human capacity to evolve in their belief system. Sure the stats don't look good but e.g. there is a move towards vegan nutrition (about the best thing people can do for the planet) despite developing countries flirting with a new, much more carnivorous diet. I have seen quite a few changes in the materialist city where I live - (nutrition, food-sharing, second-hand initiatives etc). The biggest mistake to make is to react (to what other people do) rather than act (take own initiative in what you believe is right). It is called empowerment and it is far more liberating than the genetic fatalist materialist worldview which is either used as an excuse by many or is simply a distorted picture that we have been brought up to believe. I know which path I am going and would prefer to die following it than settle for passivity and fatalism - with the latter we might as well die now. The wizzards have failed to understand that we have an inner technology that is far more important to develop than the external high energy-cost solutions they propose
