I think he left something out. It wasn't just agriculture and industrialization. He touched upon it once when he mentioned a population decline from plague. Improvements in medical care, especially vaccines and antibiotics, also led to a rapid spike in population.

The difference between a crop and a weed is, a weed has the will to survive.

The Haber-Bosch process probably deserves to be mentioned by name as one of the great accomplishments in history as it relates to growing food more easily.

Small correction: There were a number of beans cultivated in the Old World before the introduction of New World beans. Fava beans, lentils, soy beans, and some others. It's the several varieties of common bean, and its relatives, that originated in the New World-- lima beans, kidney beans, black beans, pinto beans, etc.

Really surprised to see this coming from a channel with less than 100 subscribers, a channel with videos this good deserves more, great content! Keep up the work! Looking forward to the next video

I love these analyses on human population and long term growth trends - it’s crazy how seemingly small changes build up overtime to create such massive results. Really cool stuff!

To put this in perspective there used to be prides of lions roaming the Greek peninsula in early human history.

This channel is going to blow up, phenomenal content, keep it up in a few years you’ll be one of the big ones 💯 %

This must be why it feels so unnatural for me to live in a city along lots of people, opposed to the countryside. I’ve tried both and I feel far more at peace in the country.

I think about this every time i leave my town and get onto the highway towards Dallas. The horizon changed by skyscrapers in the distance. At night, endless lines of moving lights in opposing directions. So many humans i will never know, or unknowingly passing by someone who may be very important in my life 10 years down the line. Everyone going about their own lives in this complex interwoven world. Different civilizations built on different morals and ethics blending together after centuries of separation and war

'I'd like some pumpkin pie' I can't even with this man lol 🤣

An interesting thing is how the largest Pre-Columbian cities in the Americas were wayyyy larger than any of their European counterparts. This is because wheat, Europe’s cash crop at the time, yielded 4 million calories per acre, while the Americas cash crops, potatoes and corn, both yielded 15 million calories per acre.

Your channel is brilliant, your explanations are concise and digestible 👍 Nothing too flashy and irritating like most of KZfaq, just straight talking explanations which I find soothing before bed. Great use of archival footage as well. Please make more, you have an avid and appreciative listener here!

Awesome video! I didn't even see the view count until after the video and was shocked to see only a thousand views, you deserve way more. Hopefully the algorithm swings in your favour with this one!

I love how this puts into perspective the state of the world and helps me understand my and everyone's place in it and therefore not take it for granted. A lesson in humility is priceless.

One element of industrializations impact on agriculture that had a significant impact in agricultural production was that we started to feed petroleum products to the horsepower. Maybe not literally true but the replacement of horses with tractors and trucks freed up a huge amount of land for human food. This wouldn't just mean on farms, a city the size of new york would have needed tens of thousands of horses for transport of everything.

I think you should also have brought up how our fertility rate is actually collapsing, and soon populations will be in decline. Still a really good and informative video though.

I'm looking forward to seeing this channel grow 💪

Fantastic work! Clearly a lot of effort goes into these but you make it look effortless. This channel is going to get millions of subs. Keep it up!

Great production quality, couple with all the appropriate uses of classic videos across. You got a sub!

Dude you literally have LESS subscribers than me, and I am posting garbage on KZfaq whenever I feel the mood for it, while you keep consistent high quality uploads... Even your microphone is 100 times better than mine... You seriously need a boost from KZfaq. I'm glad I got this video recommended to me

It just happened as that day I left my Minecraft Villager breeder on, I left 2 and came to see my game at 2 fps and 10299 entities rendered

Bottomline: All the tasty food crops come from South America. That is a great value addition. Sad thing is what South America got in return.

"I like some pumpkin pie." Me too actually.

"Tomatoes, Peppers, Squash, Maize, Beans, Cocoa, Peanuts, Potatoes, Pineapples." "Grains, Livestock, Communicable diseases." Worst trade deal in the history of trade deals.

I would love a video about the Antebellum/Midwest Era, your videos are very interesting and easy to digest, i’ve been binging and loving how much i’m learning. Cheers!

Great Video! Informative and the audio quality was great. Look forward to your future vids

Quite a number of people used to die before they reached childbearing age, thus limiting population growth. Advancements in medicine which allowed safer births (less women and children dying in childbirth) and prevented and cured childhood diseases thus allowing more people to reach adulthood played a huge part in the population explosion of the 20th century.

I just found your channel today. Love it. Already subscribed.

Absolute gem of a channel the algorithm has served me up here. First video that came up was the arabic naming convention so I assumed you were a linguist given how good your pronunciation was, but your breadth of knowledge is insane

I found my next fav channel!!! Great stuff

Great video! You have a new subsciber! One question: how much did improvements in health, medicine, hygiene and vaccinations in the 1700 to 1900 hundreds increase population growth? I'm under the imprression that these things lead to more and more children surviving early childhood, thus increasing population. I would also love to hear more about you! Are you a teacher, professor or an amateur historian? Anyway, KEEP UP THE GOOD WORK!

You got a new sub, please continue producing good quality contents like these. Love your voice btw!

Super entertaining , worthy of a lot more recognition than it's getting . Keep up the good work man

Man, I love this channel and I don't know how I didn't find it before.

Amazing channel, I have a feeling you will get a lot of subscribers with time. Glad to be one of the early ones.

Nice informing, fun and high quality video. keep it up!

The book '1492' by Charles C. Mann, gives an excellent summary of the 'Columbian exchange'. I recommend to anyone who found this video interesting. Thanks for the video, I've subscribed and look forward to more content!

I just finished watching all of your videos, this channel is awesome!

Love this channel and this video!

Congratulations on 8 billion subscribers!

Interesting that for almost the entire timeline of human evolution our diets did not include foods like corn, beans, and potatoes.

Thanks for the video essay! Well done! All those years listening to Dan Carlin and Mary Beard and others, I was thinking of a video version that would rock. You made me think long hard and deep about history, with the plus of well-designed graphics and maps. Thanks for the nuggets!

Love your channel! Keep making videos

I hope the number of subscribers to your channel will grow exponentially like the human population has.

Awesome quality, great info. Earned a subscriber and I will definitely spread your channel to friends and family 👍

This channel has great potential

Love the little flashbacks! Great channel, just subbed 👍

When I was a spry bright-eyed bushy-tailed 20-something in college, I didn't really like going to Natural Sciences class... Now, as an old fart, I find myself filling my leisure time watching these videos... thanks, professor!

This video was recommended outta nowhere 😆 but it's very interesting and in line of what I usually watch in youtube

Excellent video, educational and insightful... Congrats for such amazing work

This video deserve more views and subscribers.

Great content!

So the exchange that was big part of why indigenous Americans died is also a big part of why Asia exploded in population, that's brutal.

I just discovered you your voice is so calm

Where did this channel come from because this is some good stuff

Great job and very interesting view on many well known facts

I liked this video so much that I forgot I had already clicked the thumbs up. This is the first time I liked a video so much that I stopped "liking" it. (Worry not, I fixed it and I like it once more.)

Excellent work.

I'm 61 years old. There were 3 billion people when I was born. Now there's 8 billion. I still hope to live another 20+ years. Will there be 9 billion then? This rate of growth is unsustainable! What other species can you name that tripled its global numbers within 1 lifespan? With all the valid concern about global warming/climate change & environmental destruction, no one wants to talk about over-population as being the primary cause! Why are rain forests being cleared and oceans running out of fish? Because there are more mouths to feed! Why is there more CO2 in the air? Because there are more people burning fuels to warm their homes or drive cars, etc. Earth is a finite place, and some day we will reach its limit to support us.

I really like these videos, can you please make a video about the industrial revolution? Like what caused it and made it possible

Do you know anything about the agriculture practiced by Native Americans prior to European contact? I feel like that topic is a good tangent from this video, and the techniques practiced were pretty interesting compared to the more homogenous methods of modern agriculture. Such as the Chinampas of the Aztec, and the clam gardens used by tribes in the pacific northwest. I'm native myself so I would love for more accessible education about the technology my culture developed.

Great video! Subbed

Excellent video.

Healthcare and sanitation is probably an important factor you have missed but regardless, great video

For the beginning: In Germany I feel like 30% of all the land area are occupied by small communes, 5% large cities, 15% forest and the other 50% are farmland.

Great content, please keed it up.

Great Video, keep it up! :)

Brillante informe ! . Por cosas del destino (y el algoritmo) termine viendo esta maravilla de trabajo. Levantare una copa de vino esta noche por iluminar mi ignorancia. Saludos desde la tierra sudamericana conquistada de Argentina

You called it industrialization. However, your video mentions ammonia but neglects to mention the development of the haber Bosch process. This process turns fossil fuels into ammonia. This fertilizer boosts harvests and feeds the world. If anything were to ever happen to the production of fossil fuels, populations would necessarily have to peak and start to fall.

If Mathusian Theory was a video 😅👍 Love your channel man, keep the good worl

Great video, already subscribed. Where de you recommend to get more info in the topic, really interesting stuff my G

Hi. What İ'm gonna say is not directly related to your topic but I think its interesting. You know "turkey" is the chicken like bird that came from America. Turkish names for " turkey" is " hindi" ( meaning related to İndia ) or " mısır" ( means Egypt) . Also corn is named " mısır" or " darı" in Turkish . Darı is ethymologically Turkish but the others are names of places / countries. We must not forget that at the beginning Columbus was thinking that the country He reached was İndia. So , probably the Turkish name "hindi" comes from İndia. And I think the other names derived from which country ( customs) these people first get these foods.

ok so we're all shocked the first time we hear Italian cuisine didn't have tomatoes til the new world, but nobody talks about the peppers! Asian cuisines without capsicum? I shudder at the thought

Im a new viewer, but im very impressed with this channel. Its hard to find genuinely historically accurate videos on youtube.

cool education, data, and footage!

Important to note that the 7 to 8 billion milestone, which occured between 2011 and 2022 taking ~11 years, will probably be the fastest in human history. The next milestone, 9 billion, will also potentially our last depending on how the demographic situation turns out (meaning we may never hit 10 billion), and it will also take at least 15 years to get to 9 billion or up to 30 years (2037 to 2050s but it's very hard to predict). So we are on a quickly decelerating curve.

Will they give the man his pumpkin pie already! >:( (stupid jokes in comments is a sure sign of the channel growth)

Great video! Why do i want pumpkin pie now?

Love your content, but I suggest you use a log scale next time so that you can explain the timeline as a whole.

Great video, very truthful however the one thing I'm surprised wasn't mentioned as to the sharp spike on the graph in the past 300 or so years is exponential growth. In order for the world to go from 100 million to 1 billion the population had to multiple by 10, but in order for the population to go from 2 billion to 4 billion it only needed to multiply by 2 so of course it didn't take as long, and same for the growth from 4 billion to 8 billion. If you look merely at total population increase that last increase (4B to 8B) is 3.1 billion more than the first increase (100M to 1B) however looking at exponential growth you see that 2x (4B to 8B) is much smaller than the 10x (100M to 1B) so of course the larger total population spike won't take as long. Imagine it this way, if I cooked rice every night, doubling how much I cooked starting with two grains tonight here's how it would go. Day 1: 2, needless to say I'm starving tonight. Day 5: 32, I've still barely eaten so I'm still starving. Day 10: 1024, this is about 1/4 of a full serving, I would certainly be dead but assuming death doesn't exist I would still be starving. Day 12: 4096, I've finally gotten a full meal. Day 16: 65536, there's now enough to feed everyone on my rec hockey team who showed up tonight (16 guys). Day 21: 2097152, there's now enough to feed the entire house of representatives and nearly the entire senate. Day 30: the number is over a billion and I could roughly feed 35% of all Alaskans. Day 41: the number is unfathomable but I would feed over 75% of the US population. Day 46: I'd have so much rice I could literally feed an entire meal to everyone on earth. According to google a serving of rice is 3000-9000 grains so I used 4000 as a meal in my examples above. If you were to chart that, the graph would look rather similar to the world population over time graph. That just goes to show how quickly exponential growth takes off as a quarter of the way through that I was just beginning to fully feed myself and by the end I feed the entire world. (incase you're wonder why I started with two grains on the first day and not one grain it's because a population can't expand/double with only one person)

Preindustrial urbanized societies had to dedicate at least a third of their farmland to feeding their horses. I worry that the modern infatuation with biofuels and methane will severely affect human food supplies

Great content

where do you get the old video clips from? they're a great addition edit: there is a credits screen lol

0:40 For example, Cracow, major city of the Polish state since few hudnret years, 150 years ago circa than 5 570 000 m2 with farmlands literally tauching it's gates. My hometown, generally considered eighter small or not big, is 70 000 000 m2 (not sure if the number includes various empty spaces, but by 'main body' of this town is circa 40 000 000 m2). That's three 0's of differenace. Major city was 150 years ago 13 times smaller than my not-big town. Currently Cracow is 327 000 000 m2. That's nearly 60 times the size difference in less than 2 centuries.

I have a theory, I observed that in my country, and in my family especially, the generation bornnin 1900's had 7 children. Some 4, some 9, and so on. My grandma only had two kids. My mom had two kids. And I see many childrenless people around me, as well as, I do not plan on bringing children to this disquisting world. So I predict that we are going to see a steady decline of the population. Altho, some families STILL have like 6 kids and such. Only time will rell.

Nice video!

Remarkable video!

The movie Soylent Green pinned the year 2022 when only the affluent could afford spacious apartments and natural food. Everyone else ate wafers of Soylent Green. That was a pretty accurate dart throw from all the way back in 1973.

I'm under the impression that there were a lot of small farming towns nearly everywhere throughout most of the medieval period and onward (and prior to, at that), and not large areas of unused land. Isn't it fairly uncontroversial to suggest that there was no more wildnerness then than now, overall? I get that density has increased significantly along with population itself increasing, but that doesn't suggest that walking from one hamlet to another entailed a long trek through a forest, I would have thought.

Informative 🎉

You're gonna be the next Vsauce combined with Ray William Johnson and Smosh. Keep it up m8

Great video. Even though there are more people in the world we are no where near outgrowing our planet. If the U.S. had the same density of population as Singapore, there would be 79 billion people in the U.S. only. Also think about it, there is 50 billion or more birds in the world but how many have you seen today? There are 3,5 trillion or more fish in but we still need sonar to find them. But without wide resource management even the underpopulated areas will not sustain it’s people. That is the power of wisdom

I’ll tell you when you’re older 😉

Thank you very much!

Good video 👍

There were fewer people in the world when I was born than there are in China and India now. There were only about 25% of the people now in CA and there were huge areas that were farmland or desert that are now cities. I much prefer farmland and desert.

The big question of our times is: when will we meet carrying capacity, and what will happen when we do?

Brilliant as usual. It is easy to forget how parabolic the population chart was when we look back at it as a linear chart which has to fit the data of the last 100 years. The amazing thing is how this growth is stretching to an end with a sharp deceleration in births around the world. So much of our housing economy and intergenerational wealth is based on the reliance of a growing population. From Japan to Eastern Europe many countries have seen their population peak and now many social expectations are breaking down as house occupancy rates drop.

They normally had dirt roads connecting towns. Maybe not villages, but sometimes they did.
