La mer expliquée à nos petits-enfants

The ocean is the cradle of life. It is at the heart of a global system upon which the equilibrium of the planet depends. It is therefore vital to preserve it, and in order to do so, vital to raise awareness in our youngest generations. Hubert Reeves, author of many works focusing on raising awareness not only of the beauty of our world, but also its fragility, describes the ocean's place within the universe, what it has to teach us about the solar system and the dangers it faces. Oceanographer Yves Lancelot takes us on a tour of the deeps and their hidden marvels. Taking the form of a dialogue between two wise grandfathers and their grandchildren, this book answers all manner of questions: How did the ocean arrive on the Earth? Why is it blue and salty? Why are there two tides each day although the moon only goes around the earth once? Will all the atoll islands disappear? Why is the sea level rising? Could all the fish disappear from the sea?
