lack of important arterial rivers or lakes requires
extensive water conservation and control measures; growth in water
usage outpacing supply; pollution of rivers from agricultural runoff
and urban discharge; air pollution resulting in acid rain; soil

South Georgia and the South Sandwich Islands
NA

Southern Ocean
increased solar ultraviolet radiation resulting from
the Antarctic ozone hole in recent years, reducing marine primary
productivity (phytoplankton) by as much as 15% and damaging the DNA
of some fish; illegal, unreported, and unregulated fishing in recent
years, especially the landing of an estimated five to six times more
Patagonian toothfish than the regulated fishery, which is likely to
affect the sustainability of the stock; large amount of incidental
mortality of seabirds resulting from long-line fishing for toothfish
note: the now-protected fur seal population is making a strong
comeback after severe overexploitation in the 18th and 19th centuries
