The world faces well-known milestones for reducing carbon dioxide emissions in the coming decades to reduce the dangers of climate change. Now an international consortium is doing the same to demand action against threats to the Pacific Ocean that they say endangers environmental and human well-being in countries rich and poor.
The Center for Ocean Solutions and Stanford University’s Hopkins Marine Station released a scientific consensus in May that spells out the grim consequences of inaction in reversing the threats of overfishing, pollution and habitat destruction, while providing a road map to recovery.
The report calls for measurable improvements to the Pacific Ocean’s health by 2020, and it fulfills a key objective set by the International Union for Conservation of Nature’s “Pacific Ocean 2020 Challenge.” The United Nation’s-affiliated group, founded in 1948 and representing 1,000 organizations worldwide, set as its first priority the release of a scientific consensus on threats to the ocean, which covers one-third of the Earth’s surface.
“This is the first time where there have been scientists and experts around the world saying, ‘These are threats, these are the solutions. Let’s take some action,’ ” said Tegan Hoffmann, an Oakland, Calif.-based consultant. She worked with Center for Ocean Solutions in corralling the 400 signatures from scientists and experts on the consensus, called the “Pacific Ocean Synthesis.”
Neil Davies, director of University of California-Berkeley’s South Pacific Research Station in French Polynesia, was one of the signers of the report. In an e-mail from the university’s distant outpost, he described the approach of the synthesis.
“It took a holistic approach to understanding the ecological health of the Pacific, with the promotion of human well-being at its heart,” Davies said.
“A non-obvious finding was that many of the same challenges are felt across this vast and diverse region,” he added. “The recommendations in the synthesis recognize that societies across the Pacific can learn from one another’s successes and failures.”
Throughout the Pacific, from the Southeast Pacific to the Pacific Northwest, pollution from sewage, plastic marine debris, toxic waste, oil spills and agricultural and urban runoff top the list of threats. Destroying productive marine and coastal habitats for development or through poor agricultural practices was next on the list, followed by commercial and recreational overfishing.
If left unchecked, this human-caused damage is sure to weaken coastal economies, reduce food supplies while populations expand, compromise public health and increase political instability, the report noted. It would also reduce marine biodiversity and damage natural ecosystems.
But the report paired details on what ails the Pacific with remedies governments across the ocean region can adopt. That’s the chief goal of the synthesis: to provide a scientifically grounded analysis – which experts worldwide support – for developing constructive policies for protecting the ocean’s health.
“The consensus statement is really giving voice to the scientific community,” said Meg Caldwell, interim director of the Center for Ocean Solutions in Monterey, Calif. “That there are scientific underpinnings to support strong policies.”
She added: “You don’t have to be a rocket scientist to figure out how to address those threats.”
