Pristine Seas

Exploring and protecting some of the last truly wild places in the ocean

SPECIAL ANNOUNCEMENT: The Chilean government announced that it has created the largest marine reserve in the Americas by protecting an area hundreds of miles off its coast roughly the size of Italy. The new area, called the Nazca-Desventuradas Marine Park, constitutes about eight percent of the ocean areas worldwide that have been declared off-limits to fishing and governed by no-take protections.

About Pristine Seas

The ocean—covering over 70 percent of the planet—sustains all life on Earth. It supplies more than half the oxygen we breathe and regulates the Earth’s climate. Its fisheries provide employment for 180 million people and food for billions worldwide, and it offers opportunities for recreation, education, and tourism.

National Geographic and Explorer-in-Residence Dr. Enric Sala launched the Pristine Seas project to find, survey, and help protect the last wild places in the ocean.

The Problem

The ocean is vast—and it is also in peril. Overfishing, pollution, climate change, and mass species extinction are all fundamentally altering the ocean’s complex ecosystems. Today we see undeniable evidence of fisheries collapse, coral reef degradation, and marine dead zones.

The Solution

A few areas of the ocean remain relatively unaltered by humans. These pristine places are key to the health of the global ocean ecosystem. Pristine Seas works to inspire governments around the world to create protected areas in these remote places in order to conserve and restore the richness of marine life and habitat.

With your support, we have helped to protect

2.5 million square kilometers of ocean territory.
