We are rich and... We don't know! Rich in everything that nature has invented over millions of years and that we earthlings have not been able to see. Most of these treasures can be found in a huge and unexplored liquid desert: the sea! Food, health, energy, housing and lifestyle... Very quickly, it will be from her that our daily life will come. From the beaches of Brittany to the depths of the abyss, via the hostile waters of Antarctica, Thalassa criss-crosses the world to meet those who have found their Eldorado and who, tomorrow, will make us "merrians".
