On a related topic, look up the series Blue Planet 2 on BBC America. It's EXCELLENT. It shows the vast variety of life in the depths of the oceans and what warming is doing to them. The answer to deep sea drilling should be a perpetual NO! 90% of all life lives down there and life may have started down there and the life there is so magnificently alien-like that I cant help but think that actual alien life would be like that. They showed fish with transparent heads where you can see their brains through their skulls (so they can look up without having to move their heads, they can actually look through their skulls!), fish that communicate by flashing different patterns of lights (we still dont know what they are saying to each other) and fish discovered 6km down that have actual feet and walk on the ocean floor and one particularly weird fish with two different sized eyes, one that always looks down and the other (much larger) that always looks up! They showed a part about coral reefs and what bleaching is doing to them and all the species dependent on them including clown fish that actually build homes inside the reefs and keep them clean.
