oceans day: books and documentaries that takes us to the depths of the sea

“The sea, once it casts its spell, holds one in its net of wonder forever”. – Jacques Cousteau, marine scientist and researcher


World Oceans Day is celebrated on June 8 and it’s vital to remember its importance. The oceans cover more than 70% of the planet. They represent our life source, supporting humanity’s sustenance and that of every other organism on Earth.


The ocean produce at least 50% of the planet’s oxygen, it is home to most of Earth’s biodiversity, and is the main source of protein for more than a billion people around the world.


For those reasons, at 3Love we want to share with you some recommendations for books and documentaries that take us to the depths of the oceans to appreciate their richness.
