Uli Kunz, born 1975, marine biologist, explorer and photographer. He dives with seals, beluga whales or sharks, in southern French caves or Norwegian fjords. During his expeditions, Uli Kunz sees how garbage, overfishing and climate change continue to destroy the oceans. In order to stir people up and so that others can see what he sees, he holds lectures all over Germany. (Chrismon)
