Antarctica's tourism policies have tightened to balance growing demand with environmental protection. The International Association of Antarctica Tour Operators (IAATO) has introduced stricter guidelines, limiting landings to 100 passengers per site and requiring one guide per 20 tourists. Some countries, like China, have seen a surge in visitors, prompting calls for enhanced regulations. The Antarctic Treaty System emphasizes minimizing ecological impact, with new measures restricting cruise ship sizes and waste management. Certain sensitive areas now have restricted access to preserve biodiversity. Operators must secure permits, ensuring compliance with environmental protocols. These changes aim to protect Antarctica's fragile ecosystem while allowing sustainable tourism.
