We have some exciting news. Starting on February 20, leaders from around the world will meet at the United Nations, where — after nearly 20 years of negotiations — they could finalize one of the most important protection measures in ocean history: the High Seas Treaty. We’ve been doing everything we can to move the treaty forward, which is why Only One is teaming up with Greenpeace, the High Seas Alliance, RISE UP, and Jane Fonda to deliver our High Seas petition to key decision-makers at the start of the conference. But in order to maximize our impact and secure the future of our ocean through this treaty being agreed, we need your help to raise the volume on this effort to new levels. Add your name to the High Seas petition — we are so close to reaching our goal of 200,000 signatures.
