Human Habitat

On Earth we enjoy a natural atmosphere that sustains human life and the propagation of plants and animals. 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.

Underground Habitats

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 Geothermal 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 cave close to the surface.

The Lunar greenhouse is an underground farm research program exploring concepts far beyond cave gardening

Underwater Habitats

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

Animal Habitats

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 ecosystems 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
