Kofi Anan says that substantial increases in illegal fishing,
tourism, bio-prospecting, climate change and depletion of the
ozone continue to pose major challenges to the Antarctic, and
governments should continue to make major efforts to secure the
area as a natural reserve devoted to peace and science. 
Illegal, unregulated and unreported fishing for toothfish in the
Southern Ocean still exceeds reported catches despite major
efforts to address such activities.  Other major areas of
concern are the increase in tourism over the last 10 years. 
There is an increase by 308% in ship-borne tourists to the
Antarctic Peninsula since 1993, up to 27,324 in 2004-5, from
6,704 in 1992-3.  An increase in high-risk, adventure
tourism has also wrought havoc on the region, creating the need
for new search and rescue missions and country liability
assessments.
