　　Antarctica has become one of the world's most popular tourist destinations. Since 1969, the average number of visitors to the continent has increased from several hundred to over 34,000 today. All activities in Antarctica are heavily regulated by the Antarctic Treaty for environmental protection purposes and the industry is largely managed by the International Association of Antarctica Tour Operators (IAATO).
