What If All Life on Earth Lived in the Oceans?

[Music] right now only 15 percent of life on earth lives in oceans today we're gonna crank that up a notch you as well as all life on earth are moving underwater would we have to evolve to pull this off species would thrive and which species would draw the short straw this is what if and here's what would happen if all life on earth lived in the oceans pack your bags because today we're moving every living species on earth underwater but before we do let's see what we're working with it's estimated that eighty percent of earth's species live on land fifteen percent in the ocean and the remaining five percent in fresh water this is going to be a big move and in order to pull this off we're going to have to adapt and fast for the sake of this video humans and animals are all going to make the evolutionary jump and adapt to breathing underwater oh your nuke gills really bring out your eyes gills like the ones currently growing from your neck are a respiration system that use a network of blood vessels they draw in oxygen from flowing water and diffuse it through gill membranes this would allow you to take in the splendors of your new underwater home and you know not drown so now that your mutated family and pets have made the descent what's life going to be like down here anyway well you may have to get over your fear of the dark both humans and animals would need to develop ways to battle darkness i'm talking about developing a better sense of touch and the ability to sense vibrations other ocean newbies may evolve to create their own light like the lanternfish in order to attract mates or prey imagine your cat chasing its own light it's also going to feel a lot colder the cold environment is going to push you into adapting your membranes to keep them liquid if you don't your fat will solidify but we know you can handle this so you'll have unsaturated fats in your membranes so that they can remain liquid and hey does anyone else have a headache this is an educated guess but i'm thinking the eight tons of added pressure per square inch may be the culprit on the plus side you're also going to have a lot more room the pacific ocean alone covers 165.2 million square kilometers that's larger than all the land on earth which measures in at 148.94 million square kilometers talk about an upgrade in real estate so provided that you and your animal friends get the evolutionary upgrades you should be okay but plants and bugs got the shaft on this one plants would need to rely solely on wind for pollination this would make it extremely difficult for plant life to be successful underwater bugs like ants and worms would bite the dust and that's a problem for our soil this is because worms help nourish the soil and ants help to aerate it this is actually super important earthworms make nutrients more available to plants since they feed on plant debris when they die the nutrients are available for the plants to absorb without this process the whole ecosystem will fall out of whack and that brings us to a bigger point everything on earth is connected in some way with everyone playing an important role in the ecosystem of the planet if we change the very fabric of how our world is structured it would change almost everything about it from the plant life to the gas contents of the atmosphere if we packed up shop and moved all life to the oceans we would have much more space the downside is life is going to be a lot less diverse thanks to the constraints of water and lack of sunlight so before we make any major moving plans what if we give it a test run and build a home away from home what if we lived in cities underwater well that's a story or another what if
