Not only do coral reefs promote biodiversity, provide vital ecosystems for life underwater, and benefit economies, they also provide natural coastal protection. But coastal erosion is getting worse, with climate change impacting reef health and contributing to sea level rise, stronger waves, and more severe storms. Luckily, ocean impact startup CCell has developed a solution to grow digitised living reefs through a process called mineral accretion. CEO Dr Will Bateman tells us how CCell is helping combat the impacts of coastal erosion.
