Why: Bangladesh may be an under-the-radar travel destination, but it is at the top of a long list of countries at extreme risk of exposure to climate change. David Hermann, a meteorologist at Aerospace and Marine International, says, "Bangladesh will disappear under water in the next 40 years." That will result in 18 million climate refugees, even with the most conservative scenario. The World Bank's Environmental Group says that increasing glacial melt from the Himalayas would "swell the Ganges and Brahmaputra rivers and their hundreds of tributaries, flooding 30-70 percent of the country each year as the water makes its way to the Bay of Bengal."
What to do: Book a 15-day tour with Wild Frontiers, which will have you wondering why it's taken you so long to visit this fascinating corner of South Asia. Without feeling rushed, the trip crisscrosses Bangladesh and pulls travelers close to lost Buddhist kingdoms, the Bengal-tiger-inhabited Sundarbans, and to the archaeological ruins of Somaparu Mahavihara.
