How Could Humans Live Underwater?

1. How Could Humans Live Underwater? Humans could live underwater. But to do this we would need to have certain things. Some of these things are important inland. By John Samra Week 5

2. Breathing Oxygen is always important. Inland it is important too. Without it we would be able to breathe. As oxygen is important inland, it is also important in the water. Water has Oxygen and Hydrogen. Put together they make a water molecule. So our problem is done. The water we drink also gives us air. If scientists find a way to stop ocean water tasting bad then we can live underwater. Gills would be a perfect way to get some air.

3. Food When we are on land we do need food. Definitely after being at the beach. So we would need to eat underwater too. If we were sharks, fish would be the alternative thing to eat. But if we were whales, plankton and krill would be the alternative thing to eat. We would need these things to live. Most marine animals have a stomach, so they need to fill it. Food is important. It helps the body to function properly. Food has vitamins and minerals to keep us healthy. Everything on land can be converted to things underwater.

4. Habitat You need a place to live in the water. An ideal place would be a sunken ship. As it creates a home for many fish. A home for fish is important. Fish need to be protected by the bigger fish, like sharks. A great place for fish to live us in an old shipwreck. As coral and algae grow on it, it is more appealing to fish. In a shipwreck, like the titanic, there are nooks and crannies that these fish can hide it. A shark wouldn’t be able to even get in those small spots. So if we were fish we would need to get into those spots, so we don’t get eaten.

5. Drink A drink is the way to keep yourself hydrated. Without it, we would die of dehydration. We don’t want to die. Ocean water is great to drink, when it doesn’t have the salt in it. But fish don’t drink with their mouths. They drink through their gills. Salt gets generated through the gills and gets thrown out somehow. If too many drinks have been “swallowed” it will also be thrown out, so it has enough water in its body. Even though fish don’t get dehydrated they do die without water in them and around them. This why fish wriggle around so much when they are taken out of water.
