Empire of Extinction: Russians and the North Pacific's Strange Beasts of the Sea, 1741-1867

In the second half of the eighteenth century, the Russian Empire-already the largest on earth-expanded its dominion onto the ocean. Through a series of government-sponsored voyages of discovery and the establishment of a private fur trade, Russians crossed and re-crossed the Bering Strait and the North Pacific Ocean, establishing colonies in Kamchatka and Alaska and exporting marine mammal furs to Europe and China. In the process they radically transformed the North Pacific, causing environmental catastrophe.
