World Oceans Day is celebrated every June 8 to raise awareness about the conservation of Earth’s oceans. In honor of World Oceans Day 2026, the United Nations is focused on marine protected areas (MPA), and the goal of protecting 30% of the world’s oceans by 2030.

The world collectively reached a third of the goal in April 2026, MPAs now cover 10% of oceans. Another 20% will need to be protected over the next four years to reach the 30% goal.

New Marine Protected Areas

The latest additions of MPAs included 284 marine or coastal protected areas in Indonesia and Thailand. This year, Ghana also declared its first MPA, the Greater Cape Three Points MPA, after more than 15 years of efforts. And in September 2025, Pakistan protected the key biodiversity hotspot of Miani Hor Lagoon, home to dalmatian pelicans (Pelecanus crispus) and great black-headed gulls (Ichthyaetus ichthyaetus).

French Polynesia, a Pacific territory controlled by France, declared the world’s largest MPA in June 2025. It covers the archipelagos’ entire exclusive economic zone; 4.8 million square kilometers (roughly 1.9 million square miles) of ocean gained official protection with overwhelming local support.
