Millions of people annually gather at hundreds of events around the world to recognize the vital importance of the “one ocean” we all share and support the present and future health of our blue planet. Last year saw 70 events in the United States alone.

This year, the 50th anniversary of the Dr. Seuss classic, One Fish, Two Fish, Red Fish, Blue Fish, adds to the fun. Individuals and families will join in kids’ art contests, photography exhibits, film showings, essay and poetry contests, treasure hunts, sleepovers and storytelling at aquariums, museums and zoos across the country. Fests will celebrate sustainable seafood, and local volunteer squads will tackle aquatic cleanup projects.

We rely on a healthy ocean with a rich diversity of life to supply oxygen, foods and medicines, as well as millions of jobs and endless opportunities for recreation and inspiration. Because all the world’s oceans are connected, environmentalists call for them to be treated as one ocean.
