Tourism, Research Increase Pollution Across Antarctica Tenfold

Scientists have raised alarms over the dramatic increase in pollution in Antarctica driven by a surge in tourism and expanding scientific research projects over the past two decades. The number of tourists visiting the continent has soared from 20,000 to 120,000 annually, contributing significantly to pollution through the burning of fossil fuels by ships, aircraft, and vehicles, which release fine particles containing heavy metals such as nickel, copper, zinc, and lead. Research expeditions also add to this pollution, with long-term projects potentially having up to ten times the impact of a single tourist. These pollutants accelerate snow melting, with one tourist estimated to promote the melting of about 100 tons of snow. While measures like banning heavy fuel oils and introducing electric-hybrid ships have been adopted, experts emphasize that more needs to be done, including transitioning to renewable energy sources, to prevent irreversible damage to Antarctica’s fragile ecosystem. Collaborative international studies, including work by Germany and Chile, underscore the urgent need for stricter environmental protections to preserve the continent’s unique biodiversity and pristine environment.
