These sealed glass bio-spheres contain many micro-organisms, algae, plants, snails, worms, and shrimp which are balanced initially in their inputs and outputs, and will maintain a biological equilibrium given only heat and sunlight. The Bio-sphere systems are totally sealed, and need no external air, water, or food. If you're looking for something to motivate you to stick with composting, or to teach your kids about why they have to put their paper in the recycle-bin, instead of the trash, the Bio-spheres might be the ticket.
Schoolteachers, Students and Parents have been amazed @ watching a self enclosed living community of animals. Feel free to submit picturues of your Bio-sphere here.
