Author. Speaker. Strategic Adviser.
Exploring how leadership, stewardship and our relationship with the ocean shape our shared future.
Blue Heart:
War, Climate and the Battle for the Ocean that Keeps us Alive
“Blue Heart is more than a book about the ocean. The ocean is both its subject and its lens, revealing the connections between leadership, stewardship, security, sustainability and humanity’s relationship with the natural world.”
Drawing on personal experience, history and systems thinking, it reveals how many of the defining challenges of our time are deeply interconnected. At its heart is a message of responsibility and agency: that by changing how we understand our relationship with nature, and with one another, we can still help shape a more resilient and hopeful future.
“Mark Mellett has written a powerful, deeply informed and urgent book that is both a timely warning and a call to conscience. Drawing on his extraordinary career at sea and his deep commitment to climate justice, he shows us that the ocean’s fate is our own.”
— Mary Robinson, Former President of Ireland
