But the Sun is tiny compared to the solar system which is tiny compared to the distance to the next star. Oh, did we mention that there are over 100 billion stars in our galaxy (which is about 100,000 light years in diameter) which is one of hundreds of billions of galaxies in just the observable universe (which might be infinite for all we know). Don't feel small. We find it liberating. Your everyday human stresses are nothing compared to this enormity that we are a part of. Enjoy the fact that we get to be part of this vastness! About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

sounds like the apocalypse in the Super Natural series

So the Khan Academy has a smartboard and knows how to use it. This was significantly more boring than any lecture I got at any point in my high school career. At least those lectures featured a human being with whom I could interact. I imagine this is the 'homework' of a flipped classroom, but seriously, this will not hold a teenagers attention.

Robert is right in my opinion and that's why some countries may show a negative growth in births because of this very fact, that the population is getting too big. So it's showing the effects of population control. Malthus is right and by 2050 the population will be about a billon but just my opinion.

i read the book Freakonomics !

The US has 5 or 6 percent of the world population and it consumes 25 percent of the world's ressources and it is probably valid for us in Canada too but nowhere else in the world is it so unbalanced. As unpleasant as it may sound, our irresponsible consumption makes us responsible for the lack of ressources in other countries like India for example. More money = more education = lower fertility rates = world population kept in check, but are we willing to stop filling up the Hummer for a Sunday afternoon ride to nowhere? Do we understand that the earth's ressources are limited? Not really, we are FREE and no one can tell us what to do, the rest of the world be damned. The only way for some to get rich is for others to be poor... but it's always been that way hasn't it?
-
Even if population stop increasing, societies keep consuming more resources once they are really developed technologically. At some point, every country may have a consumption similar to the US or Uk or France, can the earth accommodate such consumption? Maybe his theory still have some relevance in that way?

we have the technology to create abundance but capitalism is the Malthusian trap. Capitalism is a genocidal system just ask Gen Smedly D Butler. this is why you see poverty. Capitalism is based on scarcity yet promotes infinite growth it's a oxymoron lol he is wrong into days day and age but capitalist want to keep the scarcity driven system to stay in power and keep it's empire. we are in a hidden genocide. the system is a game of musical poverty chains and is the most wasteful system ever invented. America is the NAZIS in the sense it kills the poor not the Jews. 40 of food is wasted in this system,they rather toss it out then to feed the poor the system creates. genocide everyday in America by the market system.

how can you talk about the line, and not use the words "carrying capacity"
-
your voice is annoying

Mr and Mrs Duggar are ignorant fucks.

DUGGAR FAMILY: 19 kids and counting. THAT FAMILY ALONE uses over 2,100 gallons of freshwater each day (each person uses over 100 gallons a day).

Considering he postulated this late 1700's is quite remarkably insightful. We are now at the point even science can't sustain the population--lack of fresh water will even cause another World War. Desalination plants is only short term--the salt and chlorine dumped back into the ocean will make it a massive dead sea.

The good thing about maths...it's irrefutable. And this...it's all math. There were 2 B when I was in college in '73. Same stuff, just more people and more hungry mouths.

it is now holland which is most dense
-
hahaa nice!
-
word i agree with all of you but think about the extra workers you would have that's more beggars or farm hands or something that could be used to make more money???? that's what i would want to know???? :)

The reason the birthrate is going down in China is because they have a law there saying that a family can only have one child. Its great. Living conditions are improving, and food supply is being replenished. Now if only the rest of the world could follow suit.

Thanks man!

The interesting thing about the start of this video is we are actually getting to the point where food, water and energy will be cause of famine and many wars.
