In this inspiring manifesto, an internationally renowned oceanographer makes the provocative case for why protecting nature makes economic sense. Enric Sala wants to change the world--and in this groundbreaking book, he shows us how. Once we appreciate how nature works, he asserts, we will understand why its preservation is economically practical and essential to our survival. In this highly readable narrative, Sala, director of National Geographic's Pristine Seas project, tells the story of his scientific awakening, the colorful mentors whose work inspired him, and his transition from academic to activism--because, as he put it, he was tired of writing the obituary of the ocean. His revelations are surprising, and sometimes counterintuitive: Lots of sharks are actually the best indicator of a healthy ocean ecosystem, and crop diversity, rather than intensive monoculture farming, is the key to planetary abundance. For decades, Sala has spearheaded ocean protection, convincing world leaders to protect areas amounting to five times the size of Texas--and he is still passionately pushing for more. Using fascinating examples from his own expeditions and groundbreaking findings from other scientists, Sala builds the case for the economic wisdom of making room for nature, even as the population builds to eight million and grows more urbanized by the decade. Both relatable and inspiring, this powerful book will change the way you think about the world--and the future.

"Shifting Baselines" explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems.
Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public.
While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.
