Seawater is NOT something you should every drink, you might think that if you need water and you are only near a ocean you should drink the water from it wrong! Seawater will make you dehydrated a lot faster than not drinking any water at all. Your body will not be able to handle the salt from the water and will draw all the freshwater from your cells therefore making you dehydrated.
Why is the ocean so crucial to us: "Protect Planet Oceanis AboutMarine Conservation." Why Are Oceans Important? ProtectPlanetOcean.org, 2010. Web. 23 Jan. 2017.
The ocean plays a key role of shaping the climate zones on land. The ocean acts as a conveyer belt between the two poles with warm and cold water this websites shows how this is done: "How Does the Ocean Affect Climate and Weather on Land?"

The ocean zones and what the include in each one. Sunlight Zone: This zone contains the most sunlight in any zone and mainly shore animals such as Sharks, Sea lions, Manta rays and Sea turtles. Twilight Zone: A small amount a light will reach this zone no plant life in this zone and the animals here are jellyfish squid and octopuses. Midnight Zone: This area gets NO sunlight reaches this zone, Animals that are found in this zone are Viperfish, Anglerfish, snipe eel, tripod fish. Abyss: This zone of the ocean is usually the description of the deep sea, majority of the creatures living here don't have a backbone such as sea spiders, hagfish and blindshrimp. Hadal zone: The deepest area of the ocean has temperatures in the single digits and has a only some life such as sea cucumbers.
The oceans temperatures decrease the lower you go and the same goes for the pressure. for example if you swim to the bottom of your swimming pool your ears will start popping or even feeling like they are gonna explode, that's pressure now you probably will not notice the temperature difference in a pool but even if you swim 30 feet deep into the ocean you will notice the temperature difference imagine the Hadal Zone!
