The BP oil spill story is developing. I was wondering if oil might be to the Earth what blood is to mammals. What does oil do, if left untouched? Does it lubricate the planet in some way or have some other function?
I have spied a couple of scary stories talking about the spill as a planet killer, that it might keep flowing for years, and that a giant gas bubble is forming under the surface which will eventually erupt.
I have also wondered about the great voids left after drilling and what happens to those and about the sinkholes that have been in the news lately. Connection?
