alanna mitchellAlanna Mitchell is a Canadian author and journalist who writes about global science issues. She specializes in investigating changes to the earth's life-support systems and travels the world in search of scientists at the centre of what's going on.



Her first book, Dancing at the Dead Sea: Tracking the World's Environmental Hotspots, came out in 2004 in Canada and in 2005 in the rest of the English-speaking world, to international praise.


One hundred and fifty years after the publication of On the Origin of Species, award-winning environmental reporter Alanna Mitchell set out to retrace the idea of evolution and grapple with the fact that a massive extinction of the planet's species was well under way. So began a three-year odyssey in which Mitchell picked up where Darwin left off, examining not just the origin but also the ultimate fate of our world.

In this issue of Toxics Link we would bring before you one of her adventures. That in the Sunken Graves of the High Arctic.



For those who live high above the Arctic Circle, survival depends on being able to read the code of snow and ice. And so they watch.”



ArcticThus began Alanna’s chronicle on Banks Island, a place considered to be one of the most remote inhabited places in the north, the westernmost island of the Arctic Archipelago. As a part of the world’s largest polar desert, Banks Island cradles a barren plain covered in permafrost. But global warming has affected the ecosystem of this remote land, too.



Alanna finds that there is too much water. Unstable, and not solid, Ice stretches to 6 or 7 kilometres and is dangerously thin and shifty. Summers do not arrive. What arrives are windy days minus summer heat. Seals are scarce and there is not enough to feed the dogs that pull the sleds. Ranges for many plants and animals have shifted towards the poles. Plants are flowering earlier, animals are breeding earlier. The ice covers on lakes and rivers in the northern hemisphere is shortened by about two weeks. The polar bears are also ill at ease. Baby polar bears live off seal pups who are born in the long ice ridges. When it melts very fast the seal pups die and hence polar bear cubs virtually starve to death. Adult polar bears are finding it tough to find suitable ice cover for their hibernation.

The musk ox now has a shorter life span. Often infected with parasites who line the stomach and ulcerate it before seeping into the ox’s blood stream, shorter winters in the Arctics mean longer life for these parasites. This translates into shorter life for the musk ox as the presence of the parasite in its system for longer-than-before time is pushing it to untimely death.

“Most people in the world never think about the Arctic, let alone consider why it’s crucial to preserve this part of the world. Why does the Arctic matter? Some try to argue it on social grounds: the Inuits and Inuvialuit of North America are indigenous people… Others are nostalgic. They don’t want this rich piece of earth’s human culture to vanish.

The snow and ice are like a hat on the top of planet. They keep the heat in the sea and land so it doesn’t rise into the atmosphere.”


But when snow and ice melts…heat rises, which in turn melts more ice and snow. Thus “melting feeds yet more melting.”

Due to greenhouse effect northern sea ice is 40 % thinner than what it was 40 years ago and covers 14 % less area than it did 25 years ago. Perma-ice is shrinking by 9 % a decade.

At the end of her visit she comes back home with lods of icy memories and "a massive piece of Arctic char, frozen solid ." Back home she cooks the fish for her two children . In her own words: " The three of us have never tasted anything so tender."
