Zoom: Coral reefs: A chronicle of a fragile world

It’s one of the biggest coral reefs in the world, unfolding its flowers and lace over a nearly three-kilometre long stretch, and one of the deepest too. This underwater treasure has for long been known to local fishermen, but its extent was unsuspected. Following a diving expedition conducted with support from UNESCO in 2021, the French explorer and photographer Alexis Rosenfeld provides us with exceptional images of this landscape.
