Only 13 percent of the planet’s oceans are unaffected by human activities, such as fishing and pollution, according to a recent study from the Wildlife Conservation Society. The study, published in Current Biology and executed in tandem with the University of Queensland, has completed the first systematic analysis of the Earth’s oceans and revealed that the only intact portions of global waters could be found in protected parts of the remote Pacific Ocean and around the poles. But even those waters have their tides turning toward becoming unsafe territories for marine wildlife.

The research comes after studies in January and February revealed dead zones of marine wildlife quadrupled since the 1950s, and industrial fishing areas now cover half of the world’s oceans. “We were astonished by just how little marine wilderness remains,” Kendall Jones, lead researcher on the project, told NPR. “The ocean is immense, covering over 70 percent of our planet, but we’ve managed to significantly impact almost all of this vast ecosystem.”

The cause of this human impression is due to enormous fishing fleets, global shipping and pollution run-offs from land. Add all of this to the distress caused by climate change, and it’s no surprise we’ve arrived at this point. Still, only 5 percent of the remaining wilderness found in the ocean resides in marine protection areas.

“Beyond just valuing nature for nature’s sake, having these large intact seascapes that function in a way that they always have done is really important for the Earth,” Jones said. “They maintain the ecological processes that are how the climate and Earth system function — [without them], you can start seeing big knock-on effects with drastic and unforeseen consequences.”

In response to mounting pressure by scientists to create a protection status for the high seas, the UN Law of the Sea Convention (UNCLOS) has planned negotiations to create a treaty in September 2018. The debate will center around cutting fishing subsidies valued at more than $4 billion by governments worldwide. According to Jones, fishing “would actually be unprofitable if it weren’t for big subsidies.” He continued by noting that “the vast majority of marine wilderness could be lost at any time, as improvements in technology allow us to fish deeper and ship farther than ever before.”
