More and more people I know, and know of, seem to be heading way south on excursions to Antarctica. What was once the realm of only the hardiest scientists and explorers is now creeping into leisure territory. These trips tend to be expensive, which limits the number of people able to go, but even so, tourism has quadrupled in the last eight years.
So it's no surprise that one of the topics of the Antarctic Treaty Consultative Meeting going on in Edinburgh right now is sustainable tourism. It's not the only topic though; scientists and advisors from 45 countries will also be discussing the effects of climate change on Antarctica and other subjects.
As someone who loves to travel, and who wants to keep traveling for a long time, I think that whether its aim is environmental or cultural preservation, or both, sustainable tourism is an increasingly vital approach for both travelers and the destinations they visit.
