- Indeed we *may* need a planet under us, and a particular one at that, if
- the environmental biologists are right about some of the things they're
- currently nattering about. Some of them think a particular magnetic field
- is important for biological development, not to mention radiation shielding.
- They seem to think that a 1 G gravity field is important as well. And on
- and on.
-
- We like to think that life is infinitely adaptable, but what it adapts
- *into* may not be recognizably human or even terrestrial under extra-
- terrestrial conditions. A long term space habitat could clarify the
- importance of the various environmental inputs supplied by Earth on
- the development and maintainence of human and non-human life.
-
- It's likely that we can artificially duplicate any conditions needed
- to maintain human life off Earth indefinitely, but we can't be sure
- that we haven't missed some subtle factor until we actually try it.
