The Pacific coast is the most iconic region of California and one of the most fascinating and rapidly changing places in the world. Densely populated, urbanized, and industrializedand also home to complex, fragile ecosystemsthe coast is the place where humanity and nature coexist in a precarious balance that is never perfectly stable. This is a dramatic snapshot of the California coasts past, present, and probable future in a time of climate change and expanding human activity. Written by two marine experts who grew up on the coast, The Edge is both an appreciation of the coasts natural and cultural uniqueness and a warning of the changes that threaten that uniqueness. As ocean levels rise, coastal communities are starting to erode, and entire neighborhoods have been lost to the sea. Coastal ecosystems and wildlife that were already stressed by human settlement now face new dangers. Fisheries, oil drilling, recreation, housing and environmental advocates compete to define the future of the region. A masterful and sweeping synthesis of environmental and social science, The Edge presents a comprehensive portrait of the history, people, communities, industries, ecology, and wildlife of the coast.
