“Too often, ocean stories focus only on what we’re losing,” said Chris Fischer, Founder and Expedition Leader of OCEARCH. “The reality is that, in the United States, we are in the midst of the Great Return to Abundance. Ocean management over the past 35 years has helped restore many marine populations to levels not seen since the 1960s. We now have a playbook for bringing ocean ecosystems back to abundance, and we have proven its success in our own waters. The question is: can we share that success with the world and ignite a global return to abundance for the benefit of future generations? When science guides conservation and communities come together, recovery is possible. World Oceans Day is a chance to celebrate progress while recommitting ourselves to the work still ahead.“
