In this podcast and thanks to Markus Reymann, director of TBA21–Academy, we dive deeper into the dramatic situation of the coral reefs to better understand Claudia Comte’s work. Marine biologists Denise Henry and David Gruber talk about corals: their importance in the ecosystem, their symbiotic relationships, and their ability to sense oncoming disasters. The notions of shape and time, and the importance of restoration—like the reef rehabilitation work developed by the Alligator Head Foundation in Port Antonio, Jamaica—become key to understanding this aquatic life-form.
