 Many
years ago, NASA scientists were studying ways to build
spaceships that could keep astronauts alive for long space
journeys. They wanted the environment inside the spaceship
to maintain itself, producing food and oxygen for the crew
and keeping the air and water clean and reusable. As part of
NASA’s experiments, they discovered how to make a
self-contained living world inside a closed glass container.
Because these tiny, living worlds were so beautiful and
helped people understand about the balance of nature, NASA
gave the technology away so that these little worlds could
be made and sold in great numbers. The tiny worlds are
called EcoSpheres®. |
