Q

Outline how Antarctica is governed

A
  • Antarctic Treaty applies to all ice shelves and land south of 60 degrees south (not the high seas)
  • ATS (Antarctic Treaty System) states there shall be no military activity or complete freedom of scientific investigation
  • Madrid Protocol states there shall be no mineral resources activities other than for scientific research- however, it is reviewed in 2048

Q

Outline how climate change is a threat to Antarctica

A
  • Western Antarctic Peninsula warmed by 3 degrees over past 50 years - 5x global average, Antarctica losing 150 billion tons of ice per year
  • ACC (Antarctic Circumpolar Current) warming faster than rest of ocean
  • Krill populations declined by 80% since 1970s possibly due to decreasing ice extent (they have less algae to feed on)
  • Emperor penguin populations declined by up to 50% in some areas due to ice melting

Q

Outline how whaling is a threat to Antarctica

A
  • IWC (International Whaling Commission) imposed a ban on commercial whaling when it was founded in 1982
  • However, Japan continued under the guise of “scientific research”
  • 2014 International Court of Justice ruled that Japan should cancel all “scientific whaling” permits in the Southern Ocean
  • However, Japan simply issued itself a new permit for killing hundreds of Antarctic Minke whales each year till 2027
  • These whales have low reproductive rates so are incapable of rebuilding their numbers quickly

Q

Outline how mining and scientific exploration is a threat to Antarctica

A
  • Madrid Protocol which bans mineral resource activity (other than for scientific research) is reviewed in 2048
  • Estimates suggest around 80 million barrels worth of oil are under Antarctic Ice - worth around $40 trillion
  • Melting ice makes resources more accessible

Q

Outline how tourism is not a threat to Antarctica

A
  • More visitors (who tend to be wealthy) raises more awareness for the conservation of Antarctica and puts more pressure on governance
  • They can also contribute to funding
  • Tourist companies must have a permit from an ATS member country

Q

Outline how mining and scientific exploration is not a threat to Antarctica

A
