March 6, 2o23 โ Nearly 200 countries have agreed to a legally-binding โhigh seas treatyโ to protect marine life in international waters, which cover around half of the planetโs surface, but have long been essentially lawless.
The agreement was signed on Saturday evening after two weeks of negotiations at the United Nations headquarters in New York ended in a mammoth final session of more than 36 hours โ but it has been two decades in the making.
The treaty provides legal tools to establish and manage marine protected areas โ sanctuaries to protect the oceanโs biodiversity. It also covers environmental assessments to evaluate the potential damage of commercial activities, such as deep sea mining, before they start and a pledge by signatories to share ocean resources.
โThis is a historic day for conservation and a sign that in a divided world, protecting nature and people can triumph over geopolitics,โ Laura Meller, Oceans Campaigner at Greenpeace Nordic, said in a statement.
The high seas are sometimes called the worldโs last true wilderness. This huge stretch of water โ everything that lies 200 nautical miles beyond countriesโ territorial waters โ makes up more than 60% of the worldโs oceans by surface area.
These waters provide the habitat for a wealth of unique species and ecosystems, support global fisheries on which billions of people rely and are a crucial buffer against the climate crisis โ the ocean has absorbed more than 90% of the worldโs excess heat over the last decades.
