Biosphere 2: Our World

didnt some nasty bacteria take over and destroy the plants and animals inside ? am i wrong about that?

A neat idea, but this example is to driven by ideology, not science. If humans really wanted a self reliant human colony, then there would be no need for an entire ecosystem, only the essential plants and animals for human survival.

it is not known what is the minimal size of an essential biosphere.... that's why they do these experiments

Keeping those plants and animals alive and able to reproduce requires an ecosystem.

Yes but it doesn't necessary need to be as complex as a real ecosystem. But given enough room, it would be nicer.

there would be on planets like mars, or if there is atomic radiation.

yes but you can't ship a whole eco system to mars... and that was the ultimate purpose.

Hi there I thank it is time to take Biosphere 2 to the Moon and mars. There is 3 ways to make this happen.
1.matter trap 2.seg 3.draw a circal around the BioSphere that is the space that will be moved.

an amazing program came across it in a lecture during grade recovery for biology too bad it failed if they could keep on proceeding and make it better maybe the dream of outerspace colonies on the moon or mars may be possible but that is just it they stopped the project cold turkey when it failed the first time

it was due to a destructive type of bacteria, i might be wrong about that however.
