All of Earth’s oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes. Timely, elegant, and passionately argued, The Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet.

The Light Eaters is a deep immersion into the drama of green life and the complexity of this wild and awe-inspiring world that challenges our very understanding of agency, consciousness, and intelligence. In looking closely, we see that plants, rather than imitate human intelligence, have perhaps formed a parallel system.

As Indigenous scientist and author of Braiding Sweetgrass Robin Wall Kimmerer harvests serviceberries alongside the birds, she considers the ethic of reciprocity that lies at the heart of the gift economy. How, she asks, can we learn from Indigenous wisdom and the plant world to reimagine what we value most? Our economy is rooted in scarcity, competition, and the hoarding of resources, and we have surrendered our values to a system that actively harms what we love. Meanwhile, the serviceberry’s relationship with the natural world is an embodiment of reciprocity.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.

Mary Siisip Geniusz has spent more than thirty years working with, living with, and using the Anishinaabe teachings, recipes, and botanical information, she shares in Plants Have So Much to Give Us, All We Have to Do Is Ask. Geniusz gained much of the knowledge she writes about from her years as an oshkaabewis, a traditionally trained apprentice, and as friend to the late Keewaydinoquay, an Anishinaabe medicine woman from the Leelanau Peninsula in Michigan and a scholar, teacher, and practitioner in the field of native ethnobotany.
