For the first time, United Nations members have agreed on a unified treaty on Saturday, March 4, 2023, to protect biodiversity in the high seas — nearly half the planet’s surface.
“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." “For the first time, we are getting a binding agreement for the high seas, which until now have hardly been protected,” Lemke said. “Comprehensive protection of endangered species and habitats is now finally possible on more than 40% of the Earth's surface.”The treaty also establishes ground rules for conducting environmental impact assessments for commercial activities in the oceans.
“This treaty will help to knit together the different regional treaties to be able to address threats and concerns across species' ranges,” Battle said.
