What If All The Oceans Became Freshwater?


Our planet is a blue planet. 71 percent of the earths surface is water. But around 97.5 percent of that water is salt
water. Only 2.5 percent is fresh. That’s not a whole lot considering how many
walks of life need fresh water in order to survive. What if, in some way shape or form, all the
salt water on earth became freshwater? That’s the question we’re asking right
now on life’s biggest questions. Hello and welcome back to life’s biggest
questions, the channel that asks the fundamental questions of life. I’m charlotte dobre. If this is your first time here, hey, how
are ya. Would love it if you subbed and turned on
the bell so you never miss one of our videos, and be sure to stick around until the end
of the video where we feature some of your comments. So, What if all the oceans became freshwater? An estimated 790 million people, which is
around 11 percent of the total population of our planet, does not have access to clean
drinking water. And that’s crazy to say because there is
so much water on planet earth, its just not consumable as salt water. If we found a cost effective way to convert
some of our oceans into fresh water, Sure, there would be plenty of drinking water to
go around, But all the salt water on earth being converted into fresh water is another
story. It definitely wouldn’t be all sunshine and
rainbows. In fact its likely that most life on our planet
would die off. But let’s not get ahead of ourselves just
yet. I’ll get to that in a couple of minutes. Here’s a fun fact, did you know that all
the oceans on earth used to be fresh water? Well it did, dear subscribers, it did. Yay facts. Around 3.8 billion years ago, the earths surface
had finally cooled down, from the rotating liquid magma ball it once was, and water vapour
was able to turn from a gas into liquid water. But it didn’t stay as freshwater for long. Shortly after the planet cooled, climatic
cycles began. When it rained, carbon dioxide in the atmosphere
dissolved into the rain, making the rain acidic. The rocks then started to erode, slowly but
surely. Rainwater then crept its way into rivers and
streams, loosening the salt and minerals, and the runoff eventually made it to the oceans. Of course this didn’t happen overnight. It took billions of years and countless rain
storms for our salty oceans to become as vast as they are today. Most of the freshwater that’s consumed by
humans is done so through agriculture. 20% is consumed by industries and 10 percent
is for domestic use. Humans and other animals need water to survive. The average human lives 80 years, and in their
lifetime, they will drink 87600 litres. But even though humans are consuming a lot
of water, we also need to consume food too. There are so many types of seafood that humans
eat that we would no longer be able to if all our oceans became freshwater. I mean listen, I could live without oysters,
but I definitely wouldn’t want to. And shrimp, crab and lobster? Fughgettabout it. There are around 230 thousand marine species
that live in the ocean, and scientists think that there could be as many as 2 million species
that haven’t been discovered yet. But if you take that salt water out of the
ocean, all those organisms would die. The organisms that are affected the most are
plankton and phytoplankton, they are at the bottom of the food chain, and when you take
them out of the equation, the rest of the food chain is affected. Think about the fact that marine microrganisms
like algae account for almost half the photosynthesis on earth. Algae pulls carbon dioxide from the atmosphere
and create a huge chunk of the oxygen that we as humans breathe…things start to get
real complicated real fast. If all the oceans became freshwater, its likely
most plants and animals, including humans, would die off. REeeel quick. If starvation and suffocation doesn’t kill
you, then everyone and everything that’s left would not be living on a recognizable
earth. With no microorganisms in the ocean creating
oxygen for us to breathe, there would be an abundance of carbon dioxide in the atmosphere. The greenhouse effect would go into overdrive,
making many parts of the earth unspeakably hot, like at the equator and others incredibly
cold, especially close to the poles. Hurricanes would be a regular occurrence,
and they would be much more severe and much more deadly. The global population is growing at an insane
rate. By 2050, its estimated that there will be
9.7 billion people on earth. The more people on earth, the more fresh water
we will need to drink, and the more food that will need to be produced. We’re definitely going to need to find a
cost effective way to convert salt water into fresh water, but turning all the salt water
into fresh water? Yeah that’s pretty much a death wish. Well there you have it, you have just heard
what would happen if all the oceans became freshwater. Tell us your thoughts down in the comments,
for now I’m going to wrap up this video by responding to some comments from my video
What if we drained the Mariana trench part 2. Sam aimson – what if bohemian rhapsody had
never been written. Waynes world wouldn’t be as iconic that’s
for sure. Concavenator Producgtions – we shouldn’t
drain the m ariana trench because Godzilla is resting at the bottom. Because logic right? Who needs logic. You’re watching lifes biggest questions
remember? Mems god – I love your voice. Athanguverymuuuch my fran.
