The innovative debt-swap initiative is the first of its kind and it could lead to an explosion of similar deals around the world.
If that happens then huge swaths of ocean could be safeguarded at a time when marine environments are increasingly threatened by pollution, climate change, overfishing, and more.
“This effort will help the people of Seychelles protect their ocean for future generations, and will serve as a model for future marine conservation projects worldwide,” DiCaprio said in a statement. “These protections mean that all species living in these waters or migrating through them are now far better shielded from overfishing, pollution, and climate change.”
Dicaprio, for his part, donated $1 million to the effort. The actor has long supported marine reserves and the conservation of coral reefs and sea creatures.
In total, the reserves cover around 81,000 square miles, an area nearly as big as Britain that’s home to extensive coral reefs and some of the rarest marine creatures in the world such as giant tortoises and sea cows, according to the non-profit.
Almost all human activity will be banned in the protected areas, including most forms of fishing, pollution, and extractive activities.
Around 30% of Seychelles marine territory is now protected, up from .04% a few years ago, the nonprofit reports.
By 2022, the island nation will nearly bring another 80,000 square miles of ocean under full protection.

Seychelles is 99% ocean and the fishing and tourism industries account for 43% of its workforce.
Enacting such major protections are an investment in the future that could allow coral reefs and fish populations recover, and open up new opportunities for ecotourism, the Guardian reports.
“If the fish are protected where they are spawning, I’ve heard they will get bigger,” Graham Green, a fisherman, told the Guardian. “We need to do it if we are going to be catching fish in 20 years.
Some on the island are skeptical about how the protections will be enforced and are concerned that the new marine reserves will infringe upon local customs, the Guardian notes.
But the two new areas establish Seychelles as a leader in the realm of marine conservation.
Around the world, around 5% of ocean is under protection and the UN is aiming to double this number by 2020.
For that to happen, the debt-swapping template pioneered by Seychelles could come in handy.
“In the next three to five years we could potentially do a billion dollars of these deals,” Rob Weary, senior director of product development at TNC, told the Guardian. “We have a sight line to that.”
