CANADA - AUGUST 13: The expedition cruise ship Lyubov Orlova, right, is anchored near an old Hudson's Bay Company whaling station in Pangnirtung, Nunavut, Canada, on Aug. 19, 2007. While comfortable Caribbean cruises still attract a steady crowd, Arctic eco-tourism, its rougher, less glamorous cousin, is growing as awareness spreads of both the region's beauty and fragility. The Lyubov Orlova is one of its flagships and reflects that down-to-earth ethos. (Photo by Hugo Miller/Bloomberg via Getty Images)
