What a nice walk along the bottom of the sea, some of the photos look like they were taken in an extraterrestrial world. About the Earth, I think it is self-governing, I don't know if you know the Gaia theory, there is a great book on the subject called "symbiotic planet" by Lynn Margulis. The only thing that does not convince me about this theory is that the Earth has not yet expelled humanity from the planet. Perhaps it is only a matter of time.

I think it's a matter of time before humanity is dealt with as the planet cannot sustain us...or more to the point we cannot live harmoniously with it. We take and take and there's only so much to give. We're our own enemy in that regard.
