RE: Life's Role in Geology Part 1: How to Stop an Exploding Planet
I like how you explain how we know things, instead of just stating facts.
I'd like more clarification about the bacteria and water thing. Surely water preexisted bacteria. So what you're saying is bacteria (or life) helps maintain and/or increase water? If there was no life, would the water slowly evaporate? Would be a lot less?
It's interesting how life requires water, and the activity of living creates the necessary ("watery") environment for further living! There might be some evolutionary advantages there for organisms that create what they need to live. And a lesson for us, who appear to be destroying what we need to live!
Venus probably had some water too- oxygen just has a tendency to want to lock itself up in rocks and CO2 in the long run. Life just helps keep it from doing so. So it's a matter of maintaining water rather tham creating it, you're right.
And yeah, there are always lessons to be learned from history, whether human or natural.
