The legacy Through blood
Jacques Cousteau has three living children, and many grandchildren, even a few great grandchildren! All who surprisingly are fascinated with nautical and marine life in one way or another. Most notably, his grandson Philippe, goes on expeditions much like his grandfather. He recently released a children's book all about marine life, and also released a film regarding orcas in captivity versus orcas in the wild with his wife.
The cousteau society
There are also ways anyone can contribute, you don't have to be from the Cousteau bloodline. The Cousteau Society is something anyone can contribute to; either by contributing financially, signing petitions, informing children and loved ones about the legacy of Cousteau and conservation. Their official mission statement is, “Educating people to understand, to love and to protect the water systems of the planet, marine and fresh water, for the well-being of future generations”They also go on expeditions for conservation and exploration, and have conservation projects.
