- 53 years ago, David Latimer (80) from Surrey planted an indoor Spiderwort in a huge glass globular bottle. He has watered it just once, in the year 1972. Since then, this self-sustaining ecosystem, has been sealed away from the outside world for around 40 years. In spite of being sealed away like that, the plant has grown very well in its own miniature ecosystem [Picture]. The only regular external energy it has received has been in the form of light. [more about this self-sustaining ecosystem and how it works]
- The EcoSphere or the Original EcoSphere takes it to the next level by introducing a shrimp in a similar setting. Like David Latimer’s bottle, this is also a self-sustaining ecosystem consisting of algae, bacteria and shrimp. The company that sells these things says that the shrimps would last for just around 10 years. Although, they also claim of 25-year-old spheres with living shrimps.
10 years is little as compared to the ecosystem discussed in the first point. But we are talking about a pet living in a completely sealed space for 10 years, without demanding food, change of water or an appointment with the vet. For these little creatures it is probably a safe haven away from the dirty oil slicked oceans and predators; or probably just a prison.
These little biospheres are a far simpler and smaller versions of our big worlds. We are like the shrimp and the trees, our algae. This diagram explains in a simple way, how these artificial, extremely simplified versions of Earth work – [Diagram]
The shrimp and algae biospheres were discovered by two scientists, the late Dr. Joe Hanson and the late Dr. Clair Folsome. Later, NASA became interested in these systems. There got interested because:
- This tiny model of the Earth could add information to NASA’s Mission to Planet Earth program for studying Earth’s biosphere.
- It could help NASA’s research on human life support systems directed toward the construction of space stations for exploring our solar system.

Random Foliage Fact:
The world’s smallest park is located in the median strip of SW Naito Parkway, approaching esplanade along the Willamette River near SW Taylor Street in downtown Portland, Oregon, United States. Mill Ends Park, a 2 ft is a circular park, has held a place in the Guinness book of Records since 1971. It isn’t a park you can send your children to. – [Wikipedia]
