Rapid growth; risks to marine/terrestrial ecosystems (disturbance, waste, non-native species).
Essential but brings waste, potential contamination, and introduction of alien species via stations and equipment.
Oil spill risk; ballast water introduces non-native marine organisms; wildlife disturbance.
Illegal, unreported, unregulated (IUU) fishing for toothfish; overfishing disrupts food webs.
Driven by global greenhouse gases: rising temperatures, reduced sea ice, ice sheet retreat, permafrost thaw.
The Antarctic Treaty System regulates activities, but cumulative impacts remain a concern.
