Tourism in Antarctica has grown dramatically. In 1985, just a few thousand people visited the area but in the season 2007/2008 more than 40,000 did the same. Increasing tourism on Antarctica can result into a threat for the vulnerable South Pole area.Antarctica is not a sovereign state and so legislation is difficult. With strict guidelines and codes of conduct, the umbrella organisation of Antarctic tour operators, IAATO, has been able to dispel many of the concerns. However, this self-regulation is no absolute guarantee for a healthy tourism industry on Antarctica.Research from Maastricht University provides a possible solution: marketable visitor rights, as already used in the climate policy by means of trading in CO2 emission rights..Source: Netherlands Organization for Scientific Research. “Tourism on Antarctica Threatening South Pole Environment; Solution Offered.” ScienceDaily.
