Sea Change: The Ecological Disaster That Nobody Sees

On September 21, in what is being advance-billed as the largest climate march in history, thousands of protesters will converge on New York City to focus public attention on the slow-motion train wreck of global warming. But while Americans are becoming increasingly aware that our industrial civilization is destabilizing the earth's climate, fewer know about another environmental disaster-in-the-making: the crisis of the global oceans.

Experts warn that we are currently facing an extinction event in the oceans which may rival the "Great Death" of the Permian age 250 million years ago, when 95 percent of marine species died out due to a combination of warming, acidification, loss of oxygen and habitat - all conditions that are rife today.

Within the past half century the oceans have been transformed from the planet's most productive bioregion into arguably its most abused and critically endangered. That is the conclusion of a report issued earlier this summer by the Global Ocean Commission, a private think tank consisting of marine scientists, diplomats and business people, which makes policy recommendations to governments.

The report catalogues a grim laundry list of environmental ills. Commercial fish stocks worldwide are being overexploited and are close to collapse; coral reefs are dying due to ocean acidification - and may be gone by midcentury; vast dead zones are proliferating in the Baltic and the Gulf of Mexico caused by an influx of nitrogen and phosphorous from petroleum-based fertilizers; non-biodegradable plastic trash - everything from tiny micro-plastic beads to plastic bags and discarded fishing gear - is choking many coastal nurseries where fish spawn; and increased oil and gas drilling in deep waters is spewing pollution and posing the risk of catastrophic spills like the Deepwater Horizon disaster which dumped an estimated 4.2 million barrels of petroleum into the Gulf of Mexico during a five-month period in 2010.

Yet these worrying trends have failed to spark public indignation. It may be a matter of "out of sight, out of mind."

"If fish were trees, and we saw them being clear-cut, we would be upset," renowned oceanographer Carl Safina observed in an interview with Truthout. "But the ocean is invisible to most people, an alien world." It is hard for those of us who only see ocean life when it ends up on our dinner plates to get worked up about its destruction, Safina said.

Nevertheless, this world under the waves is vital to our survival, according to Sylvia Earle, former National Oceanic and Atmospheric Administration (NOAA) chief scientist. "The ocean is alive; it is a living minestrone soup with an even greater diversity of life than on the land," Earle told Truthout. "It is where most of our oxygen is created and carbon is taken out of the atmosphere. With every breath you take, you need to thank the ocean."
