UXBRIDGE,
Canada, Apr 24 (IPS) - Everyone loves penguins, but few will know that
Thursday is World Penguin Day. Fewer still are those who know penguins
are threatened with extinction by climate change and giant fishing
trawlers from Europe and Asia stalking the oceans around Antarctica.
Penguins
are a protected species, but the factory-sized trawlers are vacuuming
up the tiny shrimp-like krill that are their main food source. The
Southern Ocean is also becoming increasingly acidic from emissions of
fossil fuels and will have a significant impact on krill populations.3
And yet efforts to create two marine protected areas in the Southern Ocean have been blocked by China, Russia and Norway.
A network of protected areas was supposed to be established last year but the
Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) failed to reach a consensus, said Donna Mattfield of the
Antarctic Ocean Alliance, a coalition of 30 scientific and environmental organisations.
All
25 CCAMLR member nations had committed to establishing a network but
could not agree on marine protected area (MPA) proposals for East
Antarctica, and the Ross Sea. They previously agreed to one small MPA in
the
South Orkney Islands, Mattfield told IPS.
"There's
no scientific justification for not going ahead with the MPAs," she
said noting that less than two percent of the world's oceans are under
any kind of protective management.
The proposed MPAs
cover several million square kilometres of the Southern Ocean with a
combination of multiple use MPAs and no-take marine reserves. A final
decision on these MPAs will come at a special CCAMLR meeting in
Bremerhaven, Germany in July.
"The Southern Ocean is
under increasing pressure from climate change and resource extraction,
but areas such as the Ross Sea and East Antarctica are amongst the least
impacted, healthiest, and most beautiful oceans in the world. They are
one of the last remaining wildernesses on the planet and deemed a
necessary 'living laboratory' by scientists", saidOnno Gross, a marine
biologist and director of Deepwave, an ocean conservation NGO.
Of
the world's 18 penguin species, 13 are now so threatened they need
special protection. In the last few years, factory trawlers have made
their way to the remote Southern Ocean to catch krill for the
fast-growing trade to supply krill as fish meal for farmed salmon.
More
recently, krill are being used to supply the booming health food and
pharmaceutical markets for omega-3 three fatty acids believed to prevent
heart disease and inflammatory conditions such as arthritis. "Omega-3 three fatty acids can be obtained from plants. We don't need them from fish," says Thilo Maack of Greenpeace.
Europeans
are subsidising the construction of supertrawlers that are plundering
the oceans off West Africa and now the Southern Ocean because there
aren't enough fish left in European waters, Maack told IPS.
He
knows of at least two German-built supertrawlers that are fishing
krill. "It's absurd. We're going to the ends of the world to find the
last few fish. We haven't learned from our mistakes," he said.
CCAMLR
has set a krill quota of 400,000 tonnes and some 50 trawlers now ply
the cold and dangerous waters. Just last week in the Ross Sea, a Chinese
supertrawler caught fire and its crew of nearly 100 had to rescued.
Luckily the trawler did not leak its thousand tonnes of diesel fuel.
Not
a great deal is known about Antarctic krill populations. They are
believed to exist in the hundreds of millions of tonnes. However the
Southern Ocean is undergoing rapid changes. Krill larvae feed on algae
living on the bottom of sea ice, which is rapidly dwindling around the
Antarctic Peninsula with rising temperatures.
According to one estimate, the number of krill in the Southern Ocean may have dropped by 80 percent since the 1970s.
CO2
emissions from fossil fuels has made seawater is 30 percent more acidic
than 50 years ago. These acid waters weaken or dissolve the shells of
many creatures like sea snails. This is already happening in parts of
the Southern Ocean. Krill will also be affected especially as
acidification worsens with more CO2 emissions, says Maack.
Without
major emissions cuts, large parts of the Southern Ocean will be too
acidic for shell-forming species, including most plankton and krill, by
2040, oceanographer Carol Turley from Plymouth Marine Laboratory in the
UK
previously told IPS. "We
are hoping Germany as host of the special CCAMLR meeting in July will
push China, Russia and Norway into agreeing to the two proposed MPAs,"
Maack said.
There is a lot riding on this decision
Mattfield believes. "It's an opportunity to create the biggest protected
area in history," she said.
