Living under water

If everyone lived under water, then there would be good and bad things about that. For example, there would have to be more expensive under water gear, such as breathing and eating instruments, and different things that people could wear, since they can't wear the same thing all the time and how they are going to wash themselves. This shows that it would be very close to impossible living, but there are still things that will make it possible. In conclusion, living under water sounds really cool and fun, but it is a very complex way of living, unless you were a mermaid or a sea animal.
