The hidden beauty of the world's oceans. From the icy oceans of our poles to remote coral islands - the world-renowned naturalist David Attenborough explores, alongside Colin Butfield, the last great wilderness of our planet: the oceans. Attenborough vividly and impressively recounts the untouched and fragile nature of selected habitats that are home to fascinating animal and plant species, the remarkable discoveries of brave marine explorers from past years, and the efforts of modern science to explore the hidden world beneath the waves more accurately. It becomes clear that the oceans, despite being so endangered today, possess a remarkable resilience, which could allow us to have a vibrant marine world again - we just need to take action. David Attenborough is a pioneer, a role model, and one of the most important global voices for the preservation of our life support systems. In all his works, one can feel the deep love, understanding, and vulnerability of nature. Anyone who dives into this important book will emerge positively transformed. The most comprehensive and profound book about our oceans. Lavishly illustrated with numerous illustrations and color images. A wake-up call to protect the last great wilderness of our planet. To be published in May 2025 in celebration of Sir David Attenborough's 99th birthday.
