The Columbian Exchange: Crash Course World History #23

In which John Green teaches you about the changes wrought by contact between the Old World and the New. John does this by exploring the totally awesome history book "The Columbian Exchange" by Alfred Crosby, Jr. After Columbus "discovered" the Americas, European conquerors, traders, and settlers brought all manner of changes to the formerly isolated continents. Disease and invasive plant and animal species remade the New World, usually in negative ways. While native people, plants, and animals were being displaced in the Americas, the rest of the world was benefitting from American imports, especially foods like maize, tomatoes, potatoes, pineapple, blueberries, sweet potatoes, and manioc. Was the Columbian Exchange a net positive? It's debatable. So debate.

[@CptRyaffio]

I find it hard to make a moral judgment on the Columbian Exchange. Mainly because it is too difficult to quantify the positive and negative results. And I doubt that the exchange would not have happened without Columbus. What I think we should take away from this is not how history could have been different, but how we can behave in future, which is the only thing that can be influenced by the study of history. This, incidentally, is what makes the study of history so important.

[@preferredpronoun3689]

No event in humanity is without its negativity nor positivity. The balance seem lost in some of the history teaching from mister Green and his crew. Humanity is a colonial species. We expand where we can - we, not nature, goes first in my opinion. This is not to say or excuse any poisoning of the environment, it's just a statement. We rather live, and shape the world to suit us, than live in a natural world were we are not masters. Such a world is social darwinism, and not what we should even suggest is a good idea, like the video above kinda does with its questioning of human expansion.

[@CptRyaffio]

Herrera saurus Social Darwinism is the concept of "survival of the fittest" applied to the social interactions between humans. If taken to its logical extreme it can lead to racism or extreme forms of anarchism and capitalism. Thankfully it has never been attempted as a political system to date (the most famous example usually given, Hitler and the Holocaust, was actually just the common and garden variety racism, homophobia and genetic culling, and the reasoning Hitler gives is mainly religious). Taking the information given above into account, questioning human expansion has little to nothing to do with social darwinism. Questioning the morality of one human group "expanding" into the territory of another violently and without regard for their lives, livelihood, culture or history is actually quite anti social darwinism. Your "statement" regarding nature, and us "go[ing] first" makes little sense on its own (if we want to survive on the long-term, we need to take a lot better care of the environment in which we live, there is no us or them, and if we ruin the planet, we will probably die out, but life in general will survive (probably only microbial life) and the universe will not care), but it makes even less sense in this context: it is a different topic. This discussion is about the morality of one human group expanding into the territory of another without regard for their lives, livelihood, culture and history, not about the facts and ethics of global climate change and mass extinctions. Concerning your statement regarding living in a natural world where we are not masters: I think you might be confusing social Darwinism with general, biological evolution, though if that is the case your concept of evolution is still flawed. Firstly, social Darwinism has little to do with how "in-touch with nature" or industrial the society in question is, and if there is a correlation it most likely is that the more industrial and "civilised" the society is, the more likely it is that the concept will show up. Secondly, regarding evolution: it is still open whether we humans have stopped evolving (mainly because we haven't been studying the question long enough to go beyond pure speculation). There is the distinct possibility that we will never stop evolving.

[@preferredpronoun3689]

Ryaffio You should start dividing your text up into* paragraphs because it's hard to read a wall of text. Also "we go first" isn't to say we should disregard nature, chop it down and not think about it too much. I did write this isn't an excuse to poisoning the environment. I see no difference between biological evolution and social darwinism in nature. Life in nature is constantly cannibalising itself in order to be the fittest. Social darwinism is exactly how we shouldn't be like. Debated whether humans have stopped evolving? Where do you get this information from? Evolution (meaning change over time) has no end product. It's just constant change and adaptation so long as life or any life form can keep up with environmental changes. The end is death.

[@CptRyaffio]

Herrera saurus I apologise for the "wall of text," there are distinct paragraphs, they may be a little unclear though, since I did not leave a blank line in between them. But if we are stooping to criticising writing style, I feel I have more complain about than you do: "You should start dividing your text up [into] paragraphs..." Regarding "we go first," I realised you said that poisoning nature should not be done, but since we are part of nature any statement expressing the sentiment that we are in any way better or more important than nature is nonsensical and ignorant. But this is beside the point: this discussion has no bearing on the original discussion. Of course natural selection plays a large role in evolution, however, equating social darwinism with biological evolution is either terribly ignorant or deliberately stupid. Social Darwinism is the application of a flawed understanding of evolution onto society. There is no "social Darwinism in nature," there is evolution, which involves natural selection, which is sometimes misinterpreted as "survival of the fittest," but social Darwinism is, by definition, a "human only" thing (or, more accurately, a moderately intelligent life-form with complex societal structures and a rudimentary understanding of biology, philosophy ethics and morality thing only). However, here as well, my point remains: this has nothing to do with the original discussion. Of course evolution has no end product in mind, I have never stated otherwise. Nor have I said that evolution has stopped or that we have stopped evolving, I have simply stated that whether we have stopped evolving is still an unanswered question, mainly because we haven't been asking the question long enough. Consider this though: with the way modern medicine is allowing severely disabled people live longer lives and some to even have children, and that even the most unattractive among us have a reasonable chance of finding a mate and producing offspring, is it not reasonable to argue that we are on the way to removing many of the selection processes that power evolution? I am not saying that this is a bad thing, mind you. But again: what bearing does this have on the ethics of the Columbian Exchange?

[@preferredpronoun3689]

Ryaffio "But if we are stooping to criticising writing style". Let's have just one more. Your sentence should really be: "But if we stop correcting each others grammar". All my point really is that I pick you, and your family over nature any day. Including any other species, you and your family is more of worth. To paraphrase Penn Jillette: "I'd strangle all chimps in the world, if it meant saving one drug addict". Not that I think you're a drug addict. I already told you I don't make a difference between social Darwinism and biological evolution. They two are the same processes. Social Darwinism is just biological evolution applied to human society, instead of calling it biological evolution. "Of course evolution has no end product in mind, I have never stated otherwise."-you "it is still open whether we humans have stopped evolving"- you again. Make up your mind.

He kept on saying that we wouldn't understand some of the jokes, but I got them so everybody just stared at me while I laughed. We got through the first 2 minutes in 20 minutes.

[@wasteofspace1234]

It was bound to happen at some point, humans have it in their nature to explore and search for greener pastures. If it wasn't Columbus it would have been the Chinese, or the Indians, even the Africans, or the Aztecs would have figured out how to build some big ships and invaded Portugal! We're a product of evolution, and we were bound to affect the world in the way we did. It was inevitable and, dare I say it, natural.

[@maelleeugene2253]

yes but if we aren't careful the human desire to evolve will cause our downfall...

It probably wouldn't have the been the Chinese. China historically has had xenophobia and was not really interested in meeting new people. Look what happened to the Zheng he voyages.

Burhan the Somali Are you suggesting that Europeans are inherently violent? Because that's pretty damn racist, and easily proved wrong by even a basic understanding of history.

Burhan the Somali You are the one who made the claim that if non-Europeans made contact with the Americas, they would not have been as brutal. That's simply bullshit. Every civilization in history has shown brutality, viciously fighting their neighbors and establishing empires based on conquest. Imperialism isn't, and never has been, exclusively European. And any old world society would have brought along the same diseases Europeans did.

If only the the exchange had happened after the discovery of germ theory or the small pox vaccine. :(

[@gearfire123]

SpazzyMcGee1337 Had that happened things would have probably ended up worse. Do you honestly think the Europeans would have given the natives vaccines? More likely they would have used the knowledge of germ theory to kill even more than they would have initially.

[@SpazzyMcGee1337]

Gearfire That's silly. Europeans weren't saints but they weren't comic book villains. There were countless missionaries trying to save Amerindian souls. There would be an equal number of Europeans trying to save their lives.

[@gearfire123]

SpazzyMcGee1337 History disagrees with you. Later in time Europeans would use smallpox blankets in attempts to kill of native americans.

[@SpazzyMcGee1337]

Gearfire That never actually happened. The professor that said it did fabricated evidence. The tactic was merely suggested.

[@gearfire123]

SpazzyMcGee1337 Suggestion is enough to show that the sentiment was still there in certain people. Also at the time of the smallpox blankets, germ theory still wasn't as developed as the time in which you're suggesting. During the time you're suggesting the ability to deliberately infect people would have been much greater. I think you have a bit too much faith in 16th century human beings.

Not sure if it's been noted since the video is freaking old :) but: At 3:31 the bubble saying how Poles called syphillis "The German Disease" goes out of The Czech Republic instead of Poland. Great video, love your History franchise :D

😦 John green literally does everything! This is crazy, I’ve just gotten into his books (which are amazing) and now I just realized this channel is home speaking, he also does other KZbin stuff I’m pretty sure. This is crazy!
