United Nations country representatives will meet again and much work remains to be done, but Saturday represented a historic step in protecting the oceans and the diversity of creatures that live there.
After more than 40 years, members of the United Nations have agreed in principle to the High Seas Agreement, which transforms about 30% of the planet's marine surface into protected areas by 2030, with the aim of restoring various endangered species.
The last agreement on the protection of the oceans was signed in 1982, but it protected only 1% of the surface of the open sea
The last agreement on the protection of the oceans was signed in 1982, but it protected only 1% of the surface of the open sea, a term that means the surface of international waters where each country has the right to fish or exploit underwater resources, mostly minerals located over 200 meters in depth, a practice used mainly by some economically strong countries such as China, India, Russia, the United States and Germany.
Economic interests were the biggest obstacle in the latest round of negotiations that began on February 20. Developing countries demanded a greater share of the profits from the "blue economy" including technology transfer.
Until the end, the subject of discussion was the agreement on the exchange of benefits from "marine genetic resources" that are used, for example, in biotechnology.
Greenpeace claims that 11 million square kilometers of ocean must be protected each year to meet the 2030 target.
Very little of the high seas is under any protection, and pollution, acidification and overfishing are growing threats.
"Countries must formally accept the agreement and ratify it as soon as possible in order for it to be implemented," said Laura Meller of Greenpeace, who attended the talks.
With the new agreement, there will be a significant limitation on the amount of fish that can be harvested, but also on trade routes that cause pollution.
Environmentalists speak of "a historic day, and a sign that in a divided world, the protection of nature can triumph over politics."
