Once upon a time, two NASA scientists, Dr. Joe Hansen and Dr. Clair Folsome got together and decided to study the Earth’s ecosphere. They needed a product they could
play god with perform experiments on, tests variables, etc., and the self-sustaining ecosphere was their end result. Self-sustaining ecospheres have been so useful for studying different environments and biospheres that they are still used by NASA today. Within this self-sustaining ecosphere you will find shrimp, algae, and other micro-organisms living inside.
The ecosphere exists on a delicate balance of shrimp breathing the oxygen in the water while nibbling on the algae and bacteria. The bacteria then breaks down the shrimp’s waste into life sustaining nutrients which the algae make use of. Then, both the bacteria and shrimp release carbon dioxide into the sphere, which the algae then use to create oxygen inside the little world. The shrimp then breathe that oxygen and the cycle repeats itself. The average lifetime of the self-sustaining ecosphere is three years, although it has been known for some to survive up to 15 years. As long as there is at least one shrimp alive, the self-sustaining cycle will continue. Remember not to drop or shake this ecosphere, and do not allow direct sunlight as it is too hot for this little world to handle.
