This is our Blue Planet- a beautiful blue marble suspended in a sea of stars.
Unlike billions of other worlds in the Milky Way, 71 per cent of our Blue Planet is covered by ocean. It's home to the greatest diversity of life on Earth but is our least explored habitat; we've better maps of Mars than of the ocean floor. Although there's still so much to learn and millions of species to discover, we know enough to understand we owe every breath we take to our oceans. If our oceans can't thrive - neither will we.
So dive into the waves and explore coral reefs that shimmer in a kaleidoscope of colours. Venture to the bottom of the ocean where creatures beyond your wildest imagination live in the dark. Chase sea otters through kelp forest seas, and join the humpback whales that glide the waters of the open ocean.
Discover all there is to love about our Blue Planet, the stories of its inhabitants, and realise how you can help protect this wilderness beneath the waves.
In collaboration with BBC Earth, this illustrated non-fiction book will capture the wonder, beauty, and emotion of the landmark Blue Planet II TV series.
