This is Planet Hope, a podcast from The Times in partnership with Rolex and its Perpetual Planet Initiative, hosted by The Story as a bonus weekly series each Sunday.Coral reefs are some of the most diverse and vibrant ecosystems on our planet. Occupying less than 0.1% of the ocean floor, they are home to a quarter of all marine life and play a crucial role in protecting coastlines. However, over the last three decades the world has lost half of its reefs from a combination of climate change, ocean acidification, overfishing and pollution. Environment Editor for The Times, Adam Vaughan is joined by marine environmentalist and entrepreneur, Titouan Bernicot to hear how he’s offering a life line to reefs through coral gardening.
