The oceans are important to all life on earth. People often don't realize this because they don't think of the ocean when they're eating salty foods or feeling the warm breeze. The ocean affects all of earth in ways we don't even realize, such as the ocean currents. These currents affect the temperature of different regions. In some places the ocean currents deliver warmth all year round. This makes it so crops can be grown year round and animals that like warmth will be plentiful for food. This current also makes it so that the earth is more hospitable. Without the ocean currents, the areas near the equator would be much more hot and the poles would be more frigid, making so people can't grow crops in the places near the equator and nobody would be able to live there, for it is too hot for animals to live there that usually would as well. This means no food so people can't live there. The ocean also produces the most evaporation which gives some countries their fresh water supply. The ocean also provides some of the salt that makes your foods taste so good. So next time you take a sip of that refreshing water, or eat one of those delicious, salty fries, take a minute to think about where it all started.
Although the oceans can provide fresh water through rain, do not drink it straight from the ocean. Ocean water can be polluted or filled with bacteria that can make you sick. Big companies use to dump waste directly into oceans and some still do, making the water not only dangerous for the ocean life, but also for people. The water should not be drank from because of the bacteria in it. These bacterias can make people very sick and may result in a trip to the hospital. These waters are also very salty, making it so that you actually get more dehydrated than you were before. This water won't clench your thirst, it will only make it worse. The salts in the water suck out the water that was already in you making you dehydrated and even more thirsty, and if you keep drinking from the ocean it can eventually lead to sickness or even kill you if you drink enough of it.
There are many zones of the ocean. These zones are the sunlight zone, twilight zone, midnight zone, the abyss, and hadal zone. In the sunlight zone you will find creatures like sea turtles, seals, sea lions, manta rays, and sharks. The sunlight zone goes from the surface of the ocean down to 656 feet in depth and is the brightest zone. Once you reach 180 feet, however, it is no longer safe for a human outside of a sub for the water pressure is to great and the temperature is to cold. In the twilight zone there is not much sunlight. You will find creatures like jellyfish, octopus, and squid, but no plant life. This zone reaches from 656 feet to 3,280 feet in depth. The midnight zone is where the sunlight no longer reaches. You will find creatures without eyes such as the viperfish, anglerfish, snipe eel, and tripod fish. This zone reaches from 3,280 feet to 13,123 feet in depth. In the abyss, you will find creatures such as the sea spider, which has no vertebrae, the blind shrimp, and the hagfish. This zone goes from 13,123 feet to 19,685 feet in depth. The final zone, the hadal zone, contains creatures such as sea cucumbers, and is mostly made of deep-water trenches and canyons. This zone extends from 19,685 feet to 36,197 feet in depth.
We use many resources from the ocean. Much of this is food. The marine life such as fish, octopus, and various crustaceans provide food for shoreline towns and cities. The ocean can also provide salt. A process is gone through to get the salt but in the end it amounts to a lot.
