Q

Why does climate change cause ocean acidification around Antarctica?

A

carbon dioxide in the air reacts with saltwater to form carbonic acid which depletes the amount of calcium carbonate in the water

25
For what reason do countries still kill whales?
for 'scientific purposes'
26
There are believed to be a lot of ............ in Antarctica.
minerals
27
There are large reserves of ............ underneath the Southern Ocean.
oil
28
So far, there hasn't been any ............ in Antarctica.
mining
29
Mining is currently ............ in Antarctica.
banned
30
Why isn't Antarctica the ideal place for mining?
it is too far away to transport machinery from any other landmass and the landscape and climate would make mining difficult and expensive
31
Why might mining not be banned in the future?
increasing demand for minerals and oil as supplies are depleted elsewhere
32
Tourism increases ............ and ............ to Antarctica.
shipping; air travel
33
What does shipping and air travel to Antarctica cause?
water and air pollution
34
What could happen if boats hit icebergs?
fuel spills
35
Tourists can ............ breeding colonies of birds.
disturb
36
Trampling damages ............ ............ and ............ the landscape.
fragile vegetation; erodes
37
What can litter and waste disposal damage?
habitats and can harm wildlife (especially because decomposition rates in cold environments are slow)
38
What might alter food webs and ecosystems?
non-native species
39
Antarctica is important for ............ and ............ research.
scientific; environmental
40
Why does scientific and environmental research require lots of facilities?
places for the researchers to live are required, in addition to roads to transport supplies and places to store fuel
41
What happened as a result of scientific and environmental research in Antarctica until the 1980s?
a lot of waste created was either burned, thrown into the sea or dumped
42
When was the Antarctic Treaty signed?
1959
43
How many countries signed the Antarctic Treaty?
53
44
What are the rules of the Antarctic Treaty?
- Antarctica should be used for peaceful reasons (no army bases or weapons are allowed on Antarctica) - countries should cooperate on scientific research in Antarctica by sharing plans, researchers and results - Antarctica should remain within the global commons - individual countries cannot make a claim to it
45
Under the 1959 treaty, all bases and equipment can be ............ at any time.
inspected
46
When was the Protocol on Environmental Protection to the Antarctic Treaty signed?
1991
47
What did the 1991 protocol ban?
mining
48
What does the 1991 protocol aim to protect?
Antarctic plants and animals
49
What does the 1991 protocol aim to regulate?
waste disposal
50
What does the 1991 protocol aim to prevent?
pollution
51
What is required for any new activities under the 1991 protocol?
Environment Impact Assessment (EIA)
52
There is ............ ............ to ensure all countries abide by the rules set out in the 1959 treaty and 1991 protocol.
no system
53
The countries involved must reach a ............ over all decisions regarding Antarctica.
consensus (this makes tackling problems slow and diffucult)
54
What is the International Whaling Commission (IWC) responsible for?
regulating whaling and ensuring that the whale population is at a sustainable level
55
What did the IWC set up in 1994?
a whale sanctuary in the Southern Ocean around Antarctica
56
Why have campaigners criticised the IWC?
for not properly monitoring the number of whales in the sanctuary
57
What is the United Nations Environment Programme (UNEP)?
a UN agency and is the main institution that governs the world environment
58
What is the UNEP responsible for in Antarctica?
reporting activity to the UN
59
Who runs the UNEP programme in Antarctica?
CCAMLR
60
What does CCAMLR aim to do?
stop illegal fishing and conserve the Antarctic ecosystem
61
How is the effectiveness of CCAMLR limited?
by countries protecting their own interests - it took five years for CCAMLR to negotiate the creation of a marine protected area in the Ross Sea, and it hasn't reduced fishing quotas in this area
62
What did the IWC introduce in 1982?
a Whaling Moratorium that banned all commercial whaling around the world
63
How has the 1982 ban of commercial whaling affected the whale population of Antarctica?
increased population
64
How is the success of the Whaling Moratorium monitored?
by estimating whale populations based on sightings and modelling
65
Which countries believe there should be a better system to monitor the Antarctic whale population?
USA and Australia
66
How could the whale monitoring system in Antarctica be improved?
by registering all whaling boats with the IWC and placing independent observers on all whaling boats (Japan and Norway oppose this)
67
What are the opinions of non-governmental organisations (NGOs), including Greenpeace, regarding the enforcement of the Whaling Moratorium
poorly enforced
68
How many whales were killed by Japanese whalers in 2018 for 'scientific research' despite the ruling?
300
69
NGOs play an important role in ............ possible threats to Antarctica and ............ its environment.
monitoring; protecting
70
Why are NGOs well positioned to observe whether countries are sticking to the laws governing Antarctica?
they don't act on behalf of a particular country
71
What is a key NGO involved in Antarctica?
Antarctic and Southern Ocean Coalition (ASOC)
72
When was ASOC formed?
1978
73
Why was ASOC formed?
a group of NGOs were concerned that some countries were planning to make it legal to search for oil, gas and minerals in Antarctica
74
What did ASOC successfully campaign to do?
make Antarctic Treaty meetings more transparent, including allowing NGOs to attend
75
ASOC is interested in protecting the Antarctic ............ and does not have any interest in trying to ............ Antarctica for resources or fishing.
environment; exploit
76
What does ASOC do today?
monitors environmental changes in Antarctica and checks whether countries are sticking to the rules (e.g. monitoring whether countries are following the 1991 Environment Protocol)
77
What does ASOC also monitor in Antarctica?
effects of climate change
78
How does ASOC monitor the effects of climate change in Anatarctica?
by checking melting ice and sea levels around Antarctica
79
What does ASOC campaign for, alongside other NGOs?
to reduce greenhouse gas emissions
80
What has the monitoring of the melting ice in Antarctica triggered?
efforts to combat climate change - more renewable energy sources can be used and individuals can reduce their impact on the environment by driving less
81
Why might global governance slow down short-term economic growth in some countries?
there may be limits on how many whales and fish can be caught limits the amount that countries can sell
82
How is limiting short-term economic growth of some countries by limiting whaling and fishing be advantageous?
it secures resources for the future
83
Global governance allows greater ............ ............ in Antarctica.
scientific exploration
84
What does collaboration allow researchers to do?
pool resources (e.g. sharing research stations)
85
Global governance allows for ............ to visit Antarctica safely and securely.
