Book excerpt: Ecology and Wonder celebrates Western Canada's breathtaking landscape. The book makes several remarkable claims. The greatest cultural achievement in the mountain region of western Canada may be what has been preserved, not what has been developed. Protecting the spine of the Rocky Mountains will preserve crucial ecological functions. Because the process of ecosystem diminshment and species loss has been slowed, an ecological thermostat has been kept alive. This may well be an important defence against future impacts of climate change in the Canadian West.
