Nations reach accord to protect marine life on high seas

For the first time, United Nations members have agreed on a unified treaty to protect biodiversity in the high seas, concluding two weeks of talks in New York

For the first time, United Nations members have agreed on a unified treaty to protect biodiversity in the high seas - representing a turning point for vast stretches of the planet where conservation has previously been hampered by a confusing patchwork of laws.

The U.N. Convention on the Law of the Sea came into force in 1994, before marine biodiversity was a well-established concept. The treaty agreement concluded two weeks of talks in New York.

An updated framework to protect marine life in the regions outside national boundary waters, known as the high seas, had been in discussions for more than 20 years, but previous efforts to reach an agreement had repeatedly stalled. The unified agreement treaty, which applies to nearly half the planet's surface, was reached late Saturday.

“We only really have two major global commons — the atmosphere and the oceans,” said Georgetown marine biologist Rebecca Helm. While the oceans may draw less attention, “protecting this half of earth’s surface is absolutely critical to the health of our planet".

Nichola Clark, an oceans expert at the Pew Charitable Trusts who observed the talks in New York, called the long-awaited treaty text "a once-in-a-generation opportunity to protect the oceans — a major win for biodiversity."

The treaty will create a new body to manage conservation of ocean life and establish marine protected areas in the high seas. And Ms. Clark said that's critical to achieve the U.N. Biodiversity Conference’s recent pledge to protect 30% of the planet’s waters, as well as its land, for conservation.

Treaty negotiations initially were anticipated to conclude on Friday, but stretched through the night and deep into Saturday. The crafting of the treaty, which at times looked in jeopardy, represents “a historic and overwhelming success for international marine protection,” said Steffi Lemke, Germany's Environment Minister.
