Well, in the deepest parts of the sea here on earth, weren't there lifeforms based on sulphur (and so), other than well where we're based on?
so these probably work different.
Why HAS it to be green?
Bet even sulphur based organisms need a heat source! I agree with Kenny, without volcanic activity, life on Mars is unlikely :-(
