What if humans could breathe underwater?

When humans can swim freely underwater like fishes, what new things will appear in life on this Earth?

Swimming skills are now one of the vital survival skills. In social life today, many people voluntarily participate in swimming classes, even many families let their children learn to swim since she was young.

For those who already know how to swim, they can experience new pleasures within the oceanic environment.

However, if one day, people can fully breathe underwater, it is certainly a great thing.

If we can breathe underwater, we can dive and admire the beauty of the reef indefinitely.

We can swim with the fishes without fear of drowning. Undersea adventure will bring many new things but how this amazing new ability will affect our daily life.

With the current body, our limbs are not effective for swimming. We do not have enough body hair or subcutaneous fat to ensure the body does not change when underwater for long periods of time.

The human eye is not sensitive to light, making it difficult to see clearly underwater. As the depth decreases, sunlight also decreases. At this point, in front of you is just a pure black.

Human ears and mouth develop to operate in the air, underwater communication seems to be extremely difficult. You cannot speak, you can only use sign language because you certainly cannot create sound under the enormous pressure of water.

Without the help of a smart device such as a mobile phone, you cannot maintain it in deep water. Meanwhile, eating under water is an even worse challenge. Have you ever overcome the challenge of eating a bread at the bottom of the lake?

However, although difficult, if able to breathe underwater, it will surely bring about a great experience.

First, it can free people from the worry of drowning . If the water rises, people can control breathing despite having to live underwater for a long time.

If we can breathe underwater , we can turn public transportation into a giant water slide. Instead of buses, trains or on foot, people can travel by swimming or by boat.

However, we must overcome some important technical barriers. Regulating the pressure of the water system around the city will consume a huge amount of electricity but the bigger problem is dirt.

In that extremely large water system, there are many germs and countless dirt particles suspended in the water. The problem of pathogens originating in the country should also be considered. Therefore, constant water needs to be cleaned, filtered, and chlorinated.

However, being able to breathe underwater will have some positive effects on our lifestyle. We will be more underwater, swim more, eat more fish and be more careful in how we use our water every day.
