Stretching 1,400 miles along the Australian coast and visible from space, the Great Barrier Reef is home to three thousand individual reefs, more than nine hundred islands, and thousands of marine species, and has alternately been viewed as a deadly maze, an economic bounty, a scientific frontier, and a precarious World Heritage site. Now the historian and explorer Iain McCalman takes us on a new adventure into the reef to reveal how our shifting perceptions of the natural world have shaped this extraordinary seascape. Showcasing the lives of twenty individuals spanning more than two centuries, The Reef highlights our profound desire to conquer, understand, embrace, and ultimately save the worlds most complex ocean ecosystem.
