TLDRHeimler’s History explores the environmental consequences of cultural connectivity through trade, focusing on the spread of agriculture and diseases. The introduction of new crops like champa rice and bananas drastically transformed landscapes and societies. Champa rice, brought to China from Vietnam, led to population booms and agricultural innovations such as terrace farming. Similarly, bananas, introduced to sub-Saharan Africa by Indonesian merchants, enabled Bantu-speaking natives to settle in areas previously uninhabitable due to their yam-based agriculture. However, increased population put a strain on lands, causing issues like overgrazing and deforestation. The video also covers the devastating impact of the Black Death, a disease that traveled via trade routes and significantly reduced Europe's population, reshaping economic structures by giving workers more leverage. The episode underlines the transformative and often detrimental environmental effects of trade and connectivity during this historical period.

    The video discusses the environmental consequences of cultural connectivity through trade, focusing on the spread of agriculture and disease. It begins with the introduction of crops like champa rice into China, which led to population growth and significant land transformation through terrace farming, and bananas into sub-Saharan Africa, enabling population migrations. The introduction of these new crops often increased populations, which increased pressure on the land, leading to environmental degradation such as overgrazing in Great Zimbabwe and deforestation in Europe. The video then transitions to the spread of diseases like the Black Death via trade routes, notably ships and caravanserai, which facilitated the movement of plague-bearing fleas. The Black Death had devastating impacts on societies, particularly in Europe, where it killed nearly half the population, leading to significant economic and social changes, including shifts in labor dynamics.

الأسئلة الشائعة

  • What was the impact of champa rice on China?

    Champa rice, introduced to China from Vietnam, was drought-resistant and could be harvested multiple times a year, leading to massive population growth and the development of terrace farming.

  • How did bananas affect sub-Saharan Africa?

    Indonesian merchants introduced bananas into sub-Saharan Africa, allowing Bantu-speaking natives to migrate to regions unsuitable for yam cultivation, significantly impacting their lifestyle and settlement patterns.

  • What were the environmental effects of population growth due to new crops?

    Population growth due to new crops put pressure on the land, leading to overgrazing in places like Great Zimbabwe and deforestation in Europe, which caused soil erosion and reduced agricultural productivity.

  • How was the Black Death spread?

    The Black Death spread via fleas that infested carriers, especially rats, and traveled along trade routes, including ships and caravanserai on the Silk Roads.

  • What were the consequences of the Black Death in Europe?

    The Black Death killed about half of Europe's population, altering economic relationships by increasing demand for labor and shifting power to workers, allowing them to negotiate better wages.

  • Who wrote a famous account of the Black Death's effects?

    Giovani Boccaccio, in his book 'The Decameron', provided a vivid account of the symptoms and social impact of the Black Death in Europe.

  • What was terrace farming and why was it important?

    Terrace farming involved cutting steps into hillsides to create farmable land, crucial for growing champa rice in previously unfarmable Chinese terrains.

  • How did the Little Ice Age impact agriculture in Europe?

    The Little Ice Age, starting in the 1300s, worsened agricultural productivity already strained by deforestation and soil erosion.

  • What change did the Black Death bring to labor negotiations?

    With fewer workers available post-Black Death, survivors gained negotiating power for better wages and conditions from lords.

    Hi and welcome back to Heimler’s History.
  • 00:00:01
    In the last video we talked about the cultural consequences of the connectivity provided
  • 00:00:06
    to cultures through trade.
  • 00:00:08
    This video is going to explore the environmental consequences of connectivity.
  • 00:00:11
    And if that sounds boring, don’t worry, by the end we’ll have talked about bananas
  • 00:00:17
    and worldwide death.
  • 00:00:19
    Let’s get to it.
  • 00:00:22
    We need to talk about two major categories of things that spread through networks of
  • 00:00:25
    exchange: agriculture and disease.
  • 00:00:27
    So let’s start with agriculture.
  • 00:00:29
    As merchants travelled from place to place they introduced crops into lands which had
  • 00:00:33
    never seen them before and that had big consequences.
  • 00:00:35
    One of the most significant of these crops is one I’ve mentioned several times in other
  • 00:00:39
    videos, namely, champa rice.
  • 00:00:40
    It was introduced to China by merchants who travelled from the Champa Kingdom in Vietnam.
  • 00:00:45
    This strain of rice was drought resistant and could be harvested several times a year.
  • 00:00:49
    This, of course, led to massive population growth in China, but the environmental impact
  • 00:00:54
    of champa rice was significant too.
  • 00:00:56
    The introduction of this crop led to the transformation of the land, namely, terrace farming.
  • 00:01:01
    This was a method of farming that made previously unfarmable land farmable by cutting steps
  • 00:01:06
    into hillsides so that you could plant rice.
  • 00:01:08
    And again, the more food that was introduced into China the more the population grew.
  • 00:01:12
    Another significant crop introduced by merchants was bananas.
  • 00:01:15
    This time it was Indonesian merchants bringing this foreign crop into subSaharan Africa.
  • 00:01:19
    And this was huge because when the Bantu-speaking natives of Africa learned to plant this crop
  • 00:01:24
    it changed the course of their entire lives.
  • 00:01:26
    Their main food staple was yams, and that means they lived in the places they could
  • 00:01:31
    grow yams.
  • 00:01:32
    But with the introduction of the banana, they could move to regions where yams couldn’t
  • 00:01:36
    grow, and spoiler alert: they did.
  • 00:01:38
    So because this Indonesian fruit was introduced into Africa, whole populations migrated.
  • 00:01:43
    And this same kind of thing happened elsewhere too and in general when new crops were introduced,
  • 00:01:48
    population increased.
  • 00:01:50
    But when population increases, that puts more pressure on the land, and as you can imagine,
  • 00:01:56
    consequences will follow.
  • 00:01:57
    For example, overgrazing in Great Zimbabwe led to such severe environmental degradation
  • 00:02:01
    that the whole city was abandoned in the late 1400s.
  • 00:02:04
    In Europe the land was changed through deforestation which eventually led to a profound erosion
  • 00:02:09
    of the soil.
  • 00:02:10
    Combine that with the Little Ice Age that began in the 1300s, and you’ve got a severely
  • 00:02:14
    contracted agricultural production.
  • 00:02:16
    Okay, those were some of the environmental effects of trade with regards to agriculture,
  • 00:02:20
    let’s look now at the spread of disease.
  • 00:02:21
    Lots of diseases spread through merchants arriving on new shores, but surely the most
  • 00:02:25
    significant of them was the Black Death or the bubonic plague.
  • 00:02:29
    Now we understand today how this disease was spread: namely through fleas.
  • 00:02:34
    So fleas would bite a carrier infected with bubonic bacteria.
  • 00:02:38
    Then the bacteria multiplies in the flea’s guts and eventually there would be so much
  • 00:02:41
    bacteria that it clogged the fly’s guts.
  • 00:02:43
    So then they would bite a human and regurgitate the bacteria into the bite.
  • 00:02:48
    And to me that’s just insulting because not only are you getting the Black Death in
  • 00:02:51
    your blood stream which will kill you in a couple days, but you’re also getting honked
  • 00:02:55
    on by a flea.
  • 00:02:56
    Now thanks to our friends the Mongols and their unrelenting lust for more land, as they
  • 00:03:00
    pushed further and further into new territories, they unknowingly brought these fleas with
  • 00:03:05
    them.
  • 00:03:06
    But the Mongols can’t bear ALL the weight of responsibility here, the spread of this
  • 00:03:08
    disease also came along trade routes, especially ships that provided homes to infected rats.
  • 00:03:14
    But not only that, as merchants travelled over land they stopped to rest in what were
  • 00:03:18
    called caravanserai.
  • 00:03:19
    These were little places that dotted the length of the Silk Roads where merchants could rest
  • 00:03:23
    and sleep.
  • 00:03:24
    However, they did so in close proximity to animals and animals have fleas.
  • 00:03:29
    So all that to say, the Black Death was a major consequence of connectivity during this
  • 00:03:33
    period.
  • 00:03:34
    And when it showed up in a town, the consequences were devastating.
  • 00:03:37
    Probably the most famous account of the effects of the Black Death come to us from a European
  • 00:03:40
    by the named of Giovani Boccaccio in his book called The Decameron.
  • 00:03:44
    Here’s a little taste:
  • 00:03:45
    "The symptoms were not the same as in the East, where a gush of blood from the nose
  • 00:03:49
    was the plain sign of inevitable death; but it began both in men and women with certain
  • 00:03:54
    swellings in the groin or under the armpit.
  • 00:03:56
    They grew to the size of a small apple or an egg, more or less, and were vulgarly called
  • 00:04:01
    tumours.
  • 00:04:02
    In a short space of time these tumours spread from the two parts named all over the body.
  • 00:04:06
    Soon after this the symptoms changed and black or purple spots appeared on the arms or thighs
  • 00:04:11
    or any other part of the body, sometimes a few large ones, sometimes many little ones.
  • 00:04:16
    These spots were a certain sign of death, just as the original tumour had been and still
  • 00:04:21
    remained.
  • 00:04:22
    And maybe Boccaccio’s best summary of the effects of the disease is this: The victims
  • 00:04:26
    ate lunch with their friends and dinner with their ancestors.
  • 00:04:30
    Yeesh.
  • 00:04:31
    Anyway, this dreadful disease found its way into many societies of Afro-Eurasia, primarily
  • 00:04:35
    by means of trade.
  • 00:04:36
    And after all was said and done, it killed huge numbers of people.
  • 00:04:41
    In fact, in Europe most estimates are somewhere in the neighborhood of half of the population.
  • 00:04:46
    Now as you can imagine, this situation had significant consequences.
  • 00:04:50
    Maybe one of the biggest was economic.
  • 00:04:52
    The Black Death changed the relationship between workers and lords in Europe, for example,
  • 00:04:56
    because now that half the population was wiped out, workers were all of the sudden pretty
  • 00:05:00
    scarce.
  • 00:05:01
    And with this higher demand for labor, power for negotiation of wages shifted squarely
  • 00:05:04
    into the hands of the surviving workers.
  • 00:05:06
    Okay, that’s what you need to know about the Environmental impact of trade.
