Reef Life is the story of how Callum Roberts, one of the world's pre-eminent marine scientists, fell in love with the abundant 'rainforests' of the ocean. It's a rich memoir of a life lived on the frontlines of planetary change. Callum's story begins, as a young university student who has never been abroad, with a summer mapping the unknown reefs of Saudi Arabia. From the moment he first clears his mask he never looks back, moving on to Egypt's Red Sea coast and from there diving, researching and fighting for ocean protection all over the world. From Australia's imperilled Great Barrier Reef to the more resilient reefs of the Caribbean, Callum has had an extraordinary underwater career. His stories are astonishing, lyrical and laced with a wonderful wry humour. They allow us priviliged access to, and understanding of, the science of our oceans and reefs. Reef Life will inspire readers to support Callum's belief that we can transform ourselves in time to rescue the future of our seas.
