Purpose
The purpose of this site is to collect and share knowledge pertaining to Closed Ecological Life Support Systems (CELSS).

Just what are CELSS, and why should I care?
CELSS are a scientific and cultural endeavor to create self-reliant regenerative environments that can support and maintain human life via biological means. There are various motivations behind the endeavor that range from better understanding the Earth's ecosystem to being able to duplicate smaller scale human habitats in space.

CELSS technology is the embodiment of the sustainability paradigm. By measuring, controlling, and recycling human waste at the most local level possible, it makes for a smaller footprint, and places less burden on the Earth's ecosphere.
The Earth's 4.5 billion year history is characterized by radical environment changes and mass extinctions. Some folks think the present environment may be imminently gearing up for another change. Whether you blame humans or not, changes are inevitable. Unless we figure out how to create our own Ecoarks?, we humans stand a pretty good chance of going the way of the other 99.9% of all life in Earth's history that is now extinct.
The only way humans can live on the Moon or Mars is by making habitats. For those who envision Earth life beyond Earth, the technology to supply our basic needs is still a long way from bearing fruit. Or any other food, for that matter! Some of us seek to remedy that.
