It is a feature of this book to introduce various looks of the sea through the distinguishing colors of each chapter. For example, the green color chip symbolizes a healthy sea forest, while the red color chip shows dark side of a sea filled with whale blood. Like this, the color chips introduced in each chapter are used to express the bright and dark side of the sea symbolically. This book was printed on soybean oil ink with low environmental pollution on 100g matte paper and thread bound to reduce bond usage.

COSMO-SLOTH, which is a compound word of COSMOS and SLOTH, is a creative research institute that values social purposes. (It means slowly but calmly and endlessly exploring the universe.) We have been contemplating various issues facing the world, such as supporting refugees in Africa and joining the environmental movement. COSMO-SLOTH will continue to present various methodologies and visions that can contribute to society in an artistic and creative way, beyond simple support.
