What would happen if Earth had double the oxygen levels?

Insects could become much larger, humans might experience increased energy, but also face potential health risks like oxygen toxicity, and more fires might occur due to increased flammability.

Why would insects grow larger with more oxygen?

Increased oxygen would allow more to enter insects' respiratory systems, enabling them to grow larger, similar to prehistoric times.

How would human health be affected by higher oxygen levels?

Humans may experience more energy and fewer illnesses initially, but could suffer from long-term health issues like oxygen toxicity, lung damage, and poor eyesight.

Would higher oxygen levels affect fires?

Yes, higher oxygen levels make things more flammable, leading to potentially more frequent and widespread fires.

What historical period had higher oxygen levels?

About 300 million years ago, during prehistoric times, Earth's atmosphere had about 30% oxygen, and insects were much larger.

Would there be environmental changes with more oxygen?

Yes, more oxygen would make the Earth’s crust and lithosphere heavier, possibly causing bodies of water to turn into hydrogen peroxide.

How does oxygen affect human body energy?

Oxygen is essential for energy production in the body, with 90% of our energy coming from it.

Could excess oxygen create health risks?

Yes, excess oxygen could lead to oxygen toxicity, cell damage, and increased free radicals in the body.

What would happen to Earth's crust with double oxygen levels?

The Earth’s crust would become heavier, potentially leading to oxidation of various elements and structural changes.

Can increased oxygen improve immune function?

Yes, increased oxygen could improve circulation and boost some immune cells, reducing the frequency of illnesses.

Résumé

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.

Chronologie

00:00:00 - 00:04:15
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.

take a deep breath we take 23,000
00:00:08
breaths a day trying to get oxygen to
00:00:10
our brain and cells oxygen is essential
00:00:13
to our survival but it's only a small
00:00:15
percentage of what's in the air we
00:00:16
breathe so what if there was more of it
00:00:19
but it caused giant insects to roam the
00:00:21
streets with everything catch fire would
00:00:25
it make you superhuman these are just a
00:00:28
few of the things we'd be dealing with
00:00:30
if the Earth's atmosphere had double the
00:00:32
amount of oxygen it has today what else
00:00:34
would happen this is what if and here's
00:00:37
what would happen if Earth's atmosphere
00:00:39
had double the amount of oxygen our
00:00:42
atmosphere contains about 20 percent
00:00:44
oxygen and roughly 78% nitrogen
00:00:47
even though oxygen is not the most
00:00:49
significant part of our atmosphere it is
00:00:51
the most important ninety percent of our
00:00:53
body's energy comes from oxygen with the
00:00:55
rest being from food and water you
00:00:58
wouldn't be able to watch this video
00:00:59
without oxygen you wouldn't be able to
00:01:00
do anything that's because you wouldn't
00:01:03
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
