The EcoSphere is the result of technology developed by scientists at NASA. They were researching self-contained communities for space explorers to live in during long-term space flights. Out of this research came the EcoSphere - an ecosystem of animal and plant life in perfect balance. Inside each EcoSphere are active micro-organisms, small shrimp, algae and bacteria, each existing in filtered sea water. Because the EcoSphere is a self-sustaining ecosystem, you never have to feed the life within. Simply provide your EcoSphere with a source of indirect natural or artificial light and enjoy this aesthetic blend of art and science, beauty and balance. http://www.eco-sphere.com)
