An international team of researchers has published data showing that the growth of tourism in Antarctica over the past two decades has led to a significant increase in pollution. The number of tourists has grown from 20 to over 120 per year. In areas where tourists land heavily and research stations operate, the concentration of heavy metals in snow is 10 times higher than it was 40 years ago. These particles enter the atmosphere from ships, aircraft, and fossil fuel-powered equipment. Scientists note that even one tourist can accelerate the melting of up to 100 tons of snow due to pollutants settling on the surface. For travelers, this means that new restrictions may be introduced in the coming years: landing limits, environmental fees, and stricter regulations for cruise lines. Tourists are advised to choose operators that adhere to IAATO (International Association of Antarctica Tour Operators) standards and prioritize eco-friendly itineraries.
