If we don't preserve the oceans from nitrate runoff and plastic and chemicals, and if we don't preserve it from acidification, and if we don't preserve it from grotesque overfishing - too much money chasing too few fish - we're going to have the most massive ecosystem on the planet in peril.
Bottom trawling is a ghastly process that brings untold damage to sea beds that support ocean life. It's akin to using a bulldozer to catch a butterfly, destroying a whole ecosystem for the sake of a few pounds of protein. We wouldn't do this on land, so why do it in the oceans?
Nobody can legitimately claim to be a marine ecologist and conservationist while continuing to eat fish. It is the ultimate form of hypocrisy.
Centuries-old habitats such as coral gardens are destroyed in an instant by bottom trawls, pulverized by weighted nets into barren plains. And global carbon dioxide emissions from human activity affect the ocean, changing the pH balance of the waters in a phenomenon known as ocean acidification.
Nothing has prepared sharks, squid, krill and other sea creatures for industrial-scale extraction that destroys entire ecosystems while targeting a few species.
I personally have stopped eating seafood.
As a child, I was aware of the widely-held attitude that the ocean is so big, so resilient that we could use the sea as the ultimate place to dispose of anything we did not want, from garbage and nuclear wastes to sludge from sewage to entire ships that had reached the end of their useful life.
Don't eat shrimp - it's one of the most unsustainable fish. For every pound that's caught, 10 or 20 pounds of other stuff is killed and dumped back overboard. It's the number one killer of juvenile sea turtles in Mexico. Two good sustainable seafood guides that I'd recommend are from the Monterey Bay Aquarium and the Blue Ocean Institute.
Marine scientists predict that by 2050 there will be no more large fish left in the ocean if we don't change our relationship with the sea.
The ocean is our planet's life support system, yet in my travels and at home, I've seen its degradation firsthand.
We know about man's impact on the ocean in terms of fishing and overfishing, but we don't really know much about what's happening underneath the water. And in fact, shipping has a role to play here, because shipping noise has contributed to damaging the acoustic habitats of ocean creatures.
We've built, drilled, and shipped indiscriminately across our oceans, with little consideration for the natural environment that is critical to the health of many of our other ocean uses, like food and recreation.
