  • 0:26 - 0:29
    It was March 11, 2020
  • 0:29 - 0:31
    when the WHO declared
  • 0:31 - 0:36
    that Covid-19 was, to all intents
    and purposes, a pandemic.
  • 0:37 - 0:43
    I remember how, until a few days before,
    many of us were rather skeptical
  • 0:43 - 0:46
    about the potential
    of this new coronavirus,
  • 0:47 - 0:49
    also on the basis of expert advice.
  • 0:50 - 0:56
    Yet on that day, on that
    11 March 2020, I wondered:
  • 0:56 - 0:59
    but if really our species,
    the Homo Sapiens,
  • 0:59 - 1:01
    face a pandemic,
  • 1:02 - 1:07
    face a health crisis,
  • 1:07 - 1:09
    a huge spread of infections,
  • 1:10 - 1:13
    we would really be able
    to plan the interventions
  • 1:13 - 1:14
    effectively?
  • 1:15 - 1:19
    At the time, it was rather difficult
    to answer this question:
  • 1:20 - 1:24
    yet I began to wonder, precisely,
  • 1:24 - 1:26
    what this infection was,
  • 1:26 - 1:27
    what it represented
  • 1:27 - 1:30
    not so much for our species,
    but also for other species.
  • 1:31 - 1:33
    In fact, we humans
  • 1:33 - 1:37
    we are definitely
    not the only animals, species
  • 1:37 - 1:41
    which faces as tough
    a challenge as a pandemic.
  • 1:41 - 1:44
    And so, starting from
    my academic background,
  • 1:45 - 1:46
    from my various experiences,
  • 1:46 - 1:48
    I have begun to consider
  • 1:49 - 1:53
    that there really are
    so many cases, in nature,
  • 1:53 - 1:56
    of infection control behaviours:
  • 1:56 - 1:58
    hygienic behaviour.
  • 1:59 - 2:03
    For example, we could mention
    the case of birds.
  • 2:03 - 2:06
    Some of these species,
    such as sparrows or flocks,
  • 2:07 - 2:11
    they use a very, I might say,
    bizarre behavior
  • 2:11 - 2:13
    which is fumigation,
  • 2:13 - 2:16
    very similar to what we do
    in the house with incense.
  • 2:16 - 2:19
    That is, they apply aromatic herbs -
  • 2:19 - 2:22
    in some cases, they are also
    cigarette butts -
  • 2:22 - 2:24
    inside the nest.
  • 2:24 - 2:29
    The purpose is to disinfect it,
    to make it more sanitized
  • 2:29 - 2:31
    to reduce the possibility
    of disease occurrence;
  • 2:31 - 2:33
    and so it's absolutely similar
  • 2:33 - 2:36
    to what we do in our homes,
    perhaps with incense.
  • 2:37 - 2:39
    And then, turning to the world of mammals,
  • 2:39 - 2:41
    we find a true master of hygiene:
  • 2:41 - 2:43
    the badger.
  • 2:43 - 2:45
    In our woods, the badger
    is a night dweller,
  • 2:45 - 2:47
    and lives in dens,
  • 2:47 - 2:50
    usually covered with mosses,
    leaves and shrubs.
  • 2:51 - 2:54
    Especially in the winter months,
  • 2:54 - 2:57
    the rate usually changes this coating,
  • 2:57 - 3:01
    exposes it to the sun
    and replaces the foliage.
  • 3:01 - 3:02
    Why is that?
  • 3:02 - 3:06
    Because it reduces the possibility
    of parasite proliferation
  • 3:06 - 3:07
    or any pathogens.
  • 3:08 - 3:13
    Besides, we have some cases
    of cosmetics, so body care.
  • 3:13 - 3:18
    The example of brown capuchine monkeys,
    these monkeys coming from South America
  • 3:18 - 3:21
    that use a kind of mosquito spray.
  • 3:22 - 3:27
    They exploit the irritating substance
    produced by the millipedes,
  • 3:27 - 3:32
    to remove mosquitoes and avoid bites.
  • 3:32 - 3:35
    And then we have the case
    of African elephants,
  • 3:35 - 3:40
    elephants using clay,
    they sprinkle it on the skin,
  • 3:40 - 3:43
    to reduce the chance of sunburn
  • 3:43 - 3:47
    which clearly could then compromise
    their immune system
  • 3:47 - 3:51
    and thus increase the risk
    of infectious diseases.
  • 3:52 - 3:55
    And so, faced with this scenario,
  • 3:55 - 3:56
    we might ask ourselves:
  • 3:56 - 3:58
    but what has this got to do,
  • 3:58 - 4:03
    with what we have, for example,
    in this current pandemic?
  • 4:03 - 4:07
    Well, if we tried to take
    a closer look at the animal world,
  • 4:08 - 4:10
    we will notice that many of the behaviors
  • 4:10 - 4:13
    that we are putting in place
    in recent months
  • 4:13 - 4:16
    are completely similar, if not identical,
  • 4:16 - 4:19
    to those that are implemented
    by other animal species.
  • 4:20 - 4:22
    And so, talking about mammals,
  • 4:22 - 4:25
    we could quote our cousins,
    the chimpanzees.
  • 4:26 - 4:30
    Indeed, according to the observations
    of the British ethologist Jane Goodall,
  • 4:31 - 4:34
    and more recently confirmed
    by scientific studies,
  • 4:34 - 4:36
    when, within the group,
  • 4:36 - 4:41
    a chimpanzee expresses
    clear symptoms of an infectious disease
  • 4:41 - 4:45
    is pushed off the group,
    even with some violence,
  • 4:46 - 4:48
    until he recuperates.
  • 4:49 - 4:52
    At that point, he can
    be reinserted into the group.
  • 4:53 - 4:57
    So in this case we see
    how the common, collective good
  • 4:57 - 5:02
    comes before the interests
    of the individuals.
  • 5:02 - 5:05
    And it's an absolutely very similar case
  • 5:05 - 5:08
    to what we might call
    "quarantine" or "social distancing"
  • 5:08 - 5:09
    for us humans.
  • 5:10 - 5:14
    Let's now focus
    on a completely different world,
  • 5:14 - 5:15
    to the world of insects.
  • 5:15 - 5:18
    in fact, domestic bees
  • 5:18 - 5:22
    are the real inventors
    of disinfectant gel.
  • 5:22 - 5:25
    Inside the hive, we find the propolis.
  • 5:26 - 5:28
    It is a substance made by bees,
  • 5:28 - 5:30
    starting from a vegetable resin,
  • 5:30 - 5:33
    and is used for a specific purpose:
  • 5:33 - 5:38
    to reduce the chance
    of infections inside the hive
  • 5:38 - 5:39
    between individuals
  • 5:39 - 5:43
    and also, somehow,
    as a disinfectant cement,
  • 5:43 - 5:45
    to seal the various cells,
  • 5:45 - 5:48
    and then make the hive even safer.
  • 5:48 - 5:49
    Why do I quote bees?
  • 5:49 - 5:54
    Because actually social insects,
    like ants or termites,
  • 5:54 - 5:57
    are a true example to us humans,
  • 5:57 - 5:59
    because many of the behaviors
    they put in place,
  • 6:00 - 6:03
    from the point of view of coordination
    as a superorganism,
  • 6:03 - 6:06
    are actually really effective behaviors
  • 6:06 - 6:08
    and that should make us think
  • 6:08 - 6:12
    as we, Homo Sapiens,
    are a social species also;
  • 6:12 - 6:14
    but we find ourselves in deep trouble
  • 6:14 - 6:18
    in coordinating and allying
    against a common enemy.
  • 6:18 - 6:22
    And so, at this point
    it would be legit to wonder:
  • 6:22 - 6:25
    can we really learn
    something from animals
  • 6:25 - 6:28
    on the subject of immunity, hygiene
  • 6:28 - 6:30
    or infection control?
  • 6:31 - 6:35
    Well, a lot of scientific studies tell us
    how, in recent years,
  • 6:35 - 6:40
    a great increase has been observed
    in so-called emerging diseases,
  • 6:40 - 6:44
    these new infections
    caused by a spillover,
  • 6:44 - 6:46
    a jump from a species to another.
  • 6:46 - 6:50
    And despite our species, Homo Sapiens,
  • 6:50 - 6:52
    they had to face in a more remote past
  • 6:53 - 6:55
    some very serious pandemics,
  • 6:55 - 6:59
    such as the plague, such as Spanish flu,
  • 6:59 - 7:05
    or more recently devastating viruses
    such as HIV and Ebola,
  • 7:05 - 7:11
    despite this, Covid 19
    admittedly surprised us,
  • 7:11 - 7:18
    and somehow shattered the idea
    of Homo Sapiens ruling the world,
  • 7:18 - 7:23
    and instead made us rediscover
    vulnerable, fragile as a species.
  • 7:24 - 7:29
    So, in light of all
    this dramatic scenario,
  • 7:29 - 7:31
    there's some good news.
  • 7:32 - 7:35
    In fact, we have a second chance today.
  • 7:35 - 7:38
    The time has come to change our vision,
  • 7:39 - 7:42
    and take a biocentric perspective
  • 7:42 - 7:46
    that allows us to recreate
    a harmonious relationship
  • 7:46 - 7:49
    with other animal species
    and with all nature.
  • 7:50 - 7:53
    Until these decades,
    our relationship with nature
  • 7:53 - 7:54
    was toxic:
  • 7:55 - 7:58
    we have polluted, we have deforested,
  • 7:58 - 8:04
    we have consumed the soil,
    destroyed habitats of animal species.
  • 8:04 - 8:08
    And today, at last,
    we really have a Second Chance.
  • 8:09 - 8:11
    So, at this point we should ask ourselves,
  • 8:11 - 8:14
    how animals could come in handy?
  • 8:14 - 8:15
    If any,
  • 8:15 - 8:17
    as we have seen in these cases,
  • 8:17 - 8:19
    we humans haven't invented much:
  • 8:19 - 8:23
    on the contrary, the animals
    have really anticipated us,
  • 8:23 - 8:24
    with great effectiveness.
  • 8:24 - 8:29
    And so, right now, maybe, we could think
  • 8:29 - 8:32
    that animals could teach us something.
  • 8:33 - 8:38
    Even, perhaps, to better manage
    a possible future pandemic.
