A future with aquatic humans
Diving in the sea, hiking up a mountain, or returning to nature does not necessarily mean that one rejects the city or human civilization. In the future, if humans can no longer live on land, perhaps they may once again live in the water.
According to the aquatic ape theory, as the ancestors of modern humans diverged evolutionarily from other apes, there was a history of adaptation to aquatic life.
The grounds for this theory come from characteristics humans do not share with other primates: characteristics such as upright walking, thin hair, thick subcutaneous fat, and the ability to consciously control breathing.
Newborn babies do not fear water and will reflexively hold their breath when submerged.
There is also a theory that human noses face down because they adapted to make it more difficult for water to enter.
If you think about it this way, it is interesting.
This year, I was able to dive a lot in the ocean waters around Okinawa. In half a year, I dived in 18 locations.
I wasn’t able to fly all over the world, so my thoughts ran to the potential of the vast ocean resources that remain on our planet.
