It's a fact of life that there will be oil spills, as long as oil is moved from place to place, but we must have provisions to deal with them, and a capability that is commensurate with the size of the oil shipments.

If somebody dumps something noxious in my back yard, the dumper is the last one I would call on to repair the damage.

Since I began exploring the ocean in the 1950s, 90 percent of the big fish have been stripped away. Tuna, sharks, swordfish, cod, halibut, you name it, the numbers have just collapsed. Also, about half of the coral reefs are gone, globally, from where they were just a few decades ago.

Ironically the very energy, the very basis of how we know what we know, has been reliant on having an energy source [necessary] to build rockets to go to the moon and Mars, to support airplanes that fly, and satellites to give us our communication.

If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.

When I arrived on the planet, there were only two billion. Wildlife was more abundant, we were less so; now the situation is reversed.
