Tiny Island Nation Just Created Ocean Sanctuary Bigger Than England — This Will Give You Hope

Quick Smiles:

• Papua New Guinea protects 77,000 square miles of ocean — larger than the entire United Kingdom
• New sanctuary safeguards the legendary Coral Triangle, home to Earth’s most diverse marine life
• Bold move launches region-wide network of ocean reserves across the Pacific

In a stunning victory for ocean conservation, Papua New Guinea has just established one of the world’s largest marine protected areas — a breathtaking 200,000 square kilometers of tropical seas now off-limits to fishing. That’s over 77,000 square miles, larger than the entire United Kingdom.

The Western Manus Marine Protected Area sits in the legendary Coral Triangle, where the Pacific and Indian Oceans meet in a spectacular explosion of marine biodiversity. This region is home to more coral and fish species than anywhere else on Earth.

But here’s what makes this even more inspiring: this isn’t just one protected area standing alone. Papua New Guinea’s bold action forms the cornerstone of the newly established Melanesian Ocean Corridor of Reserves, a network of marine sanctuaries that will stretch across the Pacific.

The timing couldn’t be more critical. The Coral Triangle supports over 130 million people who depend on these waters for food and livelihoods, and it’s been called the “Amazon of the seas” for its incredible diversity.

By creating this massive sanctuary, Papua New Guinea is giving countless marine species — from tiny reef fish to migrating whales — a safe haven to recover and thrive. Scientists believe protected areas like this are essential for rebuilding ocean health and ensuring future generations can experience the wonder of vibrant coral reefs.

This is what real environmental leadership looks like: a small island nation stepping up to protect our shared ocean heritage for the entire world.
