Chronologie

  • 00:00:00 - 00:05:00

    The video explores the intricate relationship between humans and the microbial kingdoms, particularly fungi, emphasizing that our existence is deeply intertwined with these organisms. It highlights how fungi recycle nutrients and contribute to the food chain, while also questioning our perception of individuality as we carry more microbes than human cells. The discussion extends to the genetic diversity provided by our microbiome, suggesting that we are part of a larger weave of life rather than isolated beings.

  • 00:05:00 - 00:11:09

    As the narrative progresses, it addresses the resilience of fungi in the face of extinction and environmental changes, contrasting their adaptive strategies with human approaches. The emergence of pathogenic fungi, such as Candida auris, raises concerns about potential pandemics, urging a reevaluation of our relationship with these organisms. The video concludes by questioning whether humanity can learn from fungi to achieve balance and sustainability in our ecosystems.

    [Music]
  • 00:00:31
    [Music] our entire world is underpinned by the microbial kingdoms that sustain life but
  • 00:00:46
    also question and threaten our existence
  • 00:00:52
    fungi is a kingdom in itself it re-embroiders death into life weaving kingdoms together
  • 00:00:59
    [Music] the microscope has opened up the realm closest to us worlds surrounding and within
  • 00:01:08
    us teeming seething complex wondrous and disturbing microbial worlds that overflow and question

    our preconceived sense of self as separate and individual [Music]

    for microbes including fungi our body is food [Music]
  • 00:01:39
    mullin sheldrake writes that the main difference between humans and fungi is that humans put
  • 00:01:46
    food into their bodies whilst fungi put their body into the food for your community of microbes
  • 00:01:54
    your microbiome your body is a planet some prefer the temperate forest of your scalp
  • 00:02:02
    some the arid plains of your forearm some the tropical forest of your crotch or armpit
  • 00:02:08
    your gut ears toes mouth eyes skin and every surface passage and cavity you possess team
  • 00:02:17
    with bacteria and fungi you carry around more microbes than your own cells [Music] fungi
  • 00:02:26
    are opportunistic scavengers they are seeking micronutrients such as zinc magnesium and
  • 00:02:33
    iron from their environment including from within our bodies
  • 00:02:39
    these finite elements originate from exploding stars in our universe's past fungi excel at
  • 00:02:46
    harvesting them from the mineral landscape making them available to the wider food chain
  • 00:02:53
    many of these essential elements that make up our body and the fungi within us are indistinguishable
  • 00:02:59
    from those churning within the furnace of the sun our bodies are matter in human form

    bodies elemental unit is the cell
  • 00:03:21
    this expansive container is the ink of biology [Music]
  • 00:03:31
    the cell came to be named as such in 1666 by the polymath robert hook who when peering
  • 00:03:37
    down the microscope thought that what he saw looked just like a monastic cell a living
  • 00:03:42
    and devotional space for a monk and so hook named this archaic carrier bag of life cell

    a word and meaning that points to the primal and ineffable power of nature as the real

    everything multiplies from this whether human fungal animal plant or other and each of these

  • 00:04:22
    again
  • 00:04:24
    the genetic diversity of humans is made possible by sharing their body with microbes it is
  • 00:04:30
    thought that collectively our microbiome contains around 100 times more genes beyond those deemed
  • 00:04:38
    human
  • 00:04:39
    from this dna perspective our bodies are overwhelmingly more microbial than human we might still come
  • 00:04:50
    to see ourselves not as individuals at all but as part of the weave of life
  • 00:04:55
    [Music] our animal bodies are architecture to entire ecosystems homes to mutually dependent
  • 00:05:13
    microbes who co-evolve our flesh and blood
  • 00:05:19
    the extinction of one animal or plant species can potentially mean the loss of its unique
  • 00:05:25
    set of microbes and since microbes are the fundamental world makers this loss threatens
  • 00:05:32
    our existence beyond comprehension [Music]
  • 00:05:35
    in this new climatic epoch from which humans can no longer extract themselves are we facing
  • 00:05:46
    the question of our own demise [Music] darwin defined intelligence as adaptation and resilience
  • 00:05:56
    which makes fungi the champions made most evident in their persistent survival through
  • 00:06:02
    all previous mass extinctions modern humankind think we can adapt to challenging situations
  • 00:06:10
    by changing our environment whereas fungi change themselves the magicians of shape shifting
  • 00:06:18
    fungi use their hyphal tips to sense probe and interpret worlds using a chemical vocabulary
  • 00:06:25
    to talk to itself it can recalibrate to new environments it can grow in every direction
  • 00:06:32
    dynamically exploring space
  • 00:06:38
    in its ability to regrow entire networks from one cell fungi could be seen and conceived
  • 00:06:46
    to be immortal [Music] numerous indigenous knowledge systems teach us that humans are
  • 00:06:56
    not at the top of the pyramid as the infants of evolution we have much to learn from other
  • 00:07:03
    species [Music]
  • 00:07:09
    fungi establish symbiotic alliances with other organisms they share and exchange nutrients
  • 00:07:15
    and byproducts with partners while also manipulating them with complex chemical compounds [Music]
  • 00:07:24
    but symbiotic life-sustaining partnerships between species are vulnerable and when environmental
  • 00:07:31
    or body conditions suddenly shift relationships can turn pathogenic and deadly
  • 00:07:39
    due to climatic changes overuse of fungicides and aggressive modern invasive medical treatments
  • 00:07:48
    we are opening new opportunities for fungi to adapt colonize and feed on us
  • 00:07:56
    fungal species such as candida have co-evolved with us living on and within our bodies
  • 00:08:05
    under stresses candida yeast cells can shape-shift evading the immune system whose phagocytes
  • 00:08:13
    and other responders usually keep the relationship in balance [Applause]
  • 00:08:23
    [Music] candida auris a recently discovered pathogen simultaneously evolved to cause disease
  • 00:08:31
    in five separate locations around the world seemingly a result of being exposed to extreme
  • 00:08:36
    heat waves in the continents where it appeared rapidly spreading it is now present everywhere
  • 00:08:42
    except Antarctica scientists are warning that we are increasingly at risk of a fungal pandemic
  • 00:08:54
    fungi also brought us penicillin reminding us that it can cure as well as kill [Music]
  • 00:09:03
    the sense of equilibrium between toxin and remedy is key to our survival
  • 00:09:08
    are we humans to continue our journey as the most lethal pathogen on this earth or can
  • 00:09:18
    we learn from other species how to heal and rebalance our world [Music] as isabel stengers
  • 00:09:27
    reminds us our continued survival demands that we learn something about how best to
  • 00:09:33
    live and die within the entanglements we have entanglement as life and as danger can we
  • 00:09:42
    still come down to earth gently or are we to be dragged violently into the rubble of
  • 00:09:53
    our own making [Music]
  • 00:10:16
    [Music] see
