Next year, the Australian Government will decide on whether to commit funding for a proposed year-round, paved aerodrome near the Australian Davis research station in East Antarctica. Scientific studies show increasing human impact on glaciers; Antarctic ice melt faster than thought. At the largest scale are the effects in Antarctica of planet-wide impacts such as global warming, ozone depletion and global contamination caused by the application of technology elsewhere in the world.
Tourism must be managed to lessen negative effects. Antarctic impacts. The majority of very low impact areas (3.7% of the oceans) occurs in the high-latitude Arctic and Antarctic poles (), in areas with seasonal or permanent ice that limits human access.However, our analyses did not account for illegal, unregulated, and unreported (IUU) fishing, which may be extensive in the Southern Ocean (), or atmospheric pollution, which may be particularly high in the Arctic ().
