Par dix-huit Mètres de Fond (1942) Jacques Cousteau

Par dix-huit mètres de fond (18 meters deep), is the first French underwater film. It was made without breathing apparatus in the Embiez islands with Philippe Tailliez and Frédéric Dumas, using a depth-pressure-proof camera case developed by mechanical engineer Léon Vèche (engineer of Arts and Métiers and the Naval College). I hope this great Jacques Cousteau video makes you realize how much we have destroyed our oceans and how pristine they used to be.
