Let’s
face it - life began under water. That automatically makes one suppose
that life is more easily sustainable beneath water. While people would
naturally be uneasy about it, there are actually plans and designs -
even construction - going on, for underwater habitats.
So
what are underwater habitats? These are structures completely or
partially beneath the water level in which people can live for extended
periods, maybe all their lives, and carry out most of the basic
day-to-day activities, such as working, resting, eating, visiting the
toilet, and sleeping. All while surrounded by marine environment.
Many
underwater habitats have been designed, built and used around the world
since the early 1960s. Mostly always they were used as research
centers, or exploration base, but most of these lacked regenerative
systems for air, water, food, electricity, and other resources. However,
recently some new underwater habitats allow for these resources to be
delivered using pipes, or generated within the habitat, rather than
manually delivered. Well, some are actually built for tourism and
recreation!
