Perhaps with knowing will come caring, and with caring, an impetus toward the needed sea change of attitude, one that combines the wisdom of science … - Sylvia A. Earle

The poet W. H. Auden said, "Thousands have lived without love; none without water." Ninety-seven percent of Earth's water is ocean. No blue, no green. If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.

(What is the single most important thing we can do for the oceans today?) Right now a disproportionate bite out of the ocean is being taken by a relatively small number of countries doing industrial fishing. We’ve got to get over this idea that wildlife from the ocean is essential for our food security. What we now are beginning to understand is the high cost of eating fish. What does it take to make a pound of tuna? A lot of halibut or cod. What makes the halibut? Smaller fish. What do they eat? Krill. Krill eat phytoplankton, zooplankton. Over the years thousands of pounds of phytoplankton make a single pound of tuna. So that tuna is expensive in terms of the carbon that it has captured. The more fish we take out of the sea, the more carbon dioxide gets released into the atmosphere.

The ocean is, in effect, our life-support system, driving and weather, governing the , stabilizing , generating most of the oxygen in the atmosphere, taking up much of the , shaping . If the ocean is in trouble, so are we.
