A sense of belonging

― By Dona Bertarelli
There is a moment, when you enter the ocean, where the world above recedes. It is quiet. Almost imperceptible. But something shifts. I have felt it in different ways over the years: crossing the ocean under sail, guided by wind and currents, in constant dialogue with the elements; diving beneath the surface, where sound softens and time stretches; and through my philanthropic work, engaging with passionate people who dedicate their lives to understanding and protecting this vital system.

Speaking
for the ocean

― By Dona Bertarelli
At the Tribune Bleue final, held at the Sorbonne University in Paris last week, I had the honor of opening the competition with a reflection on what drives us to speak, and on what it means to speak for something that cannot speak for itself: the ocean.

Pew Bertarelli Ocean Legacy Applauds Chile for Protecting Over Half of Its Ocean Waters

Conservation begins with understanding the places closest to us, and few are closer to our team than Lake Geneva itself. A few weeks ago, our team gathered at Nyon Castle for a lunchtime of learning and team building, organized in partnership with Natures en Fête. Anne-Sophie Deville from Musée du Léman took us with passion through the history and biology of Lake Geneva, from its glacial origins to the life its waters hold today, before the conversation continued over a shared lunch. A lake this old still has much to teach, leaving us with a deeper appreciation for the waters we see every day. @anneso_what @musee_du_leman @nef_nyon

“What is the point of speaking, if our words change nothing about the silence of the ocean?” With those words, our founder Dona Bertarelli, chair of the jury, took the stage to introduce the finale of La Tribune Bleue, co-organized with Deep Blue Foundation few weeks ago. Then, one by one, eleven young voices broke through that silence like waves breaking on the shore. This French public speaking competition has become a current of its own, carrying the next generation’s voice for the ocean through the art of eloquence. @deepwblue @donabertarelli #TribuneBleue #Ocean #Youth #PublicSpeaking #Sorbonne

A word from
our founder

"What began as a deep love for the sea has grown into a mission to protect it, not only for its beauty, but for its vital role in sustaining life on Earth. True progress isn’t measured by what we take from Nature, but by how well we give back: to people, to the living world that sustains us, from wildlife to the plants and animals we share our lives with, and to those who will come after us."
