Book excerpt: Ian McAllister, conservationist, photographer, and longtime Great Bear Rainforest resident, takes us on a deeply personal journey from the headwaters of the region’s unexplored river valleys down to the hidden depths of the offshore world. Globally renowned for its astonishing biodiversity, the Great Bear Rainforest is also one of the most endangered landscapes on the planet, where First Nations people fight for their way of life as massive energy projects threaten entire ecosystems. This stunning collection of photographs and personal narrative is the product of twenty-five years of McAllister’s research, exploration, and campaigning for the spectacular area he calls home.
