Resumo

TLDRThe video explores the hypothetical scenario where Earth's atmosphere contains double the current oxygen levels. This would result in several drastic changes. Insects might grow to enormous sizes due to increased oxygen intake, reminiscent of prehistoric times. Humans could initially experience increased energy and enhanced health benefits, such as fewer illnesses, due to better oxygen circulation and immune function. However, long-term exposure to high oxygen levels poses risks like oxygen toxicity, lung damage, and vulnerability to free radicals. Additionally, the environment would become more flammable, leading to increased risk of fires globally. The Earth's crust would become heavier and could potentially oxidize, altering environmental structures. While this oxygen-rich scenario has both potential benefits and dangers, it underscores the delicate balance of our current atmosphere.

    The video explores the scenario of Earth's atmosphere having double its current oxygen levels, which would lead to dramatic changes for all life forms. With the atmosphere consisting of about 20% oxygen presently, doubling it would cause insects to grow significantly larger, resembling prehistoric times when it was at 30%. This alteration would energize humans, possibly reducing diseases and enhancing physical performance, but might also introduce severe health problems like oxygen toxicity and increase the risk of widespread fires due to higher flammability. Moreover, Earth's mass and the chemistry of its crust would change, leading to more oxidation, potentially turning water bodies into hydrogen peroxide. Ultimately, while certain benefits appear, such as increased energy and reduced disease prevalence, the downsides like increased fire risks and potential health issues make this scenario perilous.

    if the Earth's atmosphere had double the

    would happen this is what if and here's

    what would happen if Earth's atmosphere

    had double the amount of oxygen our

    wouldn't be able to watch this video

    without oxygen you wouldn't be able to
  • 00:01:00
    do anything that's because you wouldn't

    be alive and not only is oxygen
  • 00:01:05
    essential for humans it's vital to all
  • 00:01:07
    life on Earth now what would happen if
  • 00:01:10
    the earth had doubled the amount of this
  • 00:01:12
    crucial element the first thing you'd
  • 00:01:14
    notice will probably be those giant bugs
  • 00:01:16
    insects breathe through tiny tubes
  • 00:01:18
    called trachea scientists have theorized
  • 00:01:21
    that if more oxygen were to enter these
  • 00:01:23
    tubes insects like spiders and
  • 00:01:25
    cockroaches would grow much larger about
  • 00:01:28
    300 million years ago during prehistoric
  • 00:01:30
    times Earth's atmosphere was 30% oxygen
  • 00:01:33
    during that time insects were much much
  • 00:01:37
    larger dragonflies were the size of
  • 00:01:39
    Hawks while some spiders were the size
  • 00:01:41
    of small birds doubling the Earth's
  • 00:01:43
    oxygen levels would mean having even
  • 00:01:45
    more oxygen in our atmosphere than they
  • 00:01:48
    did back then our insects would be even
  • 00:01:50
    more enormous although these giant
  • 00:01:53
    insects might scare the pants off you
  • 00:01:55
    you can feel better knowing that you'd
  • 00:01:57
    have the energy to outrun them with a
  • 00:01:59
    higher oxygen level you'd notice you
  • 00:02:01
    have much more energy the human
  • 00:02:03
    endurance records of today would quickly
  • 00:02:04
    be shattered after everyone gets more
  • 00:02:06
    oxygen
  • 00:02:07
    you'd also be more alert more oxygen in
  • 00:02:10
    your body improves your circulation and
  • 00:02:12
    increases your energy humanity would
  • 00:02:15
    seem much less diseased and you'd call
  • 00:02:16
    it sick a lot less or would you a type
  • 00:02:20
    of infection-fighting immune cells known
  • 00:02:22
    as neutrophils would occur more often
  • 00:02:24
    keeping you healthier you'd get a lot
  • 00:02:26
    fewer colds you'd be like Superman well
  • 00:02:29
    not quite
  • 00:02:30
    the increased amount of oxygen your
  • 00:02:32
    body's getting could also lead to some
  • 00:02:34
    serious long-term health problems with
  • 00:02:37
    increased levels of oxygen humans would
  • 00:02:39
    have an increased chance of oxygen
  • 00:02:41
    toxicity this happens when humans are
  • 00:02:43
    exposed to higher oxygen levels than
  • 00:02:45
    their bodies are normally used to over
  • 00:02:47
    time this could lead to lung damage poor
  • 00:02:49
    eyesight and cells not being able to
  • 00:02:51
    reproduce having too much oxygen in your
  • 00:02:53
    body creates free radicals these atoms
  • 00:02:56
    look for other electrons to pair up with
  • 00:02:58
    when this happens it can cause damage to
  • 00:03:00
    your body and your DNA oh yeah and what
  • 00:03:04
    about all those crazy fires we mentioned
  • 00:03:06
    well with more oxygen in the atmosphere
  • 00:03:08
    things would catch on fire more easily
  • 00:03:11
    generally speaking when you can't start
  • 00:03:13
    a fire it's due to the lack of oxygen
  • 00:03:15
    with there being even more o2 in the
  • 00:03:18
    atmosphere think how easily everything
  • 00:03:19
    would catch fire I think California
  • 00:03:22
    forest fires are bad expect those to
  • 00:03:24
    happen all around the world even wet
  • 00:03:27
    vegetation would have a chance of
  • 00:03:29
    burning and as for the planet as a whole
  • 00:03:31
    well for one we'd have a lot more mass
  • 00:03:34
    oxygen isn't just in our atmosphere it
  • 00:03:37
    also plays a large part in the Earth's
  • 00:03:38
    crust and with more oxygen the crust
  • 00:03:41
    would be heavier making the lithosphere
  • 00:03:43
    heavier than our atmosphere this would
  • 00:03:46
    cause things to oxidize including large
  • 00:03:48
    bodies of water turning into hydrogen
  • 00:03:50
    peroxide
  • 00:03:51
    so some good and some bad comes from
  • 00:03:54
    this but luckily you can take a sigh of
  • 00:03:56
    relief knowing that our atmosphere only
  • 00:03:58
    has 20% oxygen and so far it's worked
  • 00:04:01
    out pretty well for us but imagine if we
  • 00:04:03
    had no oxygen well that sounds like a
  • 00:04:05
    story for another what if
  • 00:04:09
