On Earth we enjoy a natural atmosphere that sustains human life and the propagation of plants and
Because we take our surrounding natural world for granted it is difficult to imagine the challenges of creating an artificial or closed environment.
To understand the requirements for human existence in space or underwater or even underground requires a stretch of the imagination.
Human Space Habitats
The development of technology to support the basic survival of humans in space, to enable human space travel and allow the ability for humans to live or work in space. Companies like Bigelow Aerospace are actively tackling the human habitat in space issue.
Early space pioneers envisioned the complexity of sustaining a closed loop environment that would make the settlement of other planets
Controlled Environment Gardening
One of the long term challenges for the habitation of space is the production of food. Future farmers are working today on growing food with closed environment gardening techniques.
Mythology has long held the existence of a civilization that dwells deep beneath the surface of the earth in an
underground or sub-terrain ecosystem. We currently do not commonly understand about the recirculation of fresh air and a replacement for sunlight.
One of the
properties of caves is a constant temperature year around.
Maybe the reference the cave man has a deeper meaning than commonly thought of as a shallow
close to the surface.
The Lunar greenhouse is an underground farm research program exploring concepts far beyond cave gardening
Underwater Habitats pose some unique challenges for long term human inhabitants. Ocean pressures seem high on the list of issues to overcome.
Rumors of a sunken city or even underwater bases have been widespread throughout folk lore.
Jules Verne's Nautilus, featured in Twenty Thousand Leagues Under the Sea, explored, gathered and farmed food from the sea.
Aquanauts live and work underwater in research programs such as NEEMO, an acronym for NASA Extreme Environment Mission Operations

Zoology has developed from a curiosity of keeping caged animals in captivity to the research and captive breading of endangered species.
Animal habitats have become more of a artificial simulation of life in the wild but still limited by space, budget and climate.
As technology evolves the possibilities of developing more complex
for nurturing and preserving plants and animals expands.
A visit to the zoo, even if it is simulated habitat still stimulates the imagination of all of us. Special smiles are always seen especially with the Giraffes and Tigers
