Also known as tourism of doom, or last chance tourism, this emerging trend involves traveling to places that are environmentally or otherwise threatened (such as the ice caps of Mount Kilimanjaro, the melting glaciers of Patagonia, or the coral of the Great Barrier Reef) before it is too late. Identified by travel trade magazine Travel Age West editor-in-chief Kenneth Shapiro in 2007 and later explored in The New York Times, this type of tourism is believed to be on the rise. Some see the trend as related to sustainable tourism or ecotourism due to the fact that a number of these tourist destinations are considered threatened by environmental factors such as global warming, overpopulation or climate change. Others worry that travel to many of these threatened locations increases an individual's carbon footprint and only hastens problems threatened locations are already facing.
