For my online class through University of Guelph Distance Education I have fallen behind due to well everything that has happened to me in the past month. But July is a new month, so I must catch up. I am taking Environment and Resources and I had to watch this video on Banks Island and my heart sank. http://www.iisd.org/publications/pub.aspx?pno=428.
Here is my take on it that I posted to my discussion boards:
As mentioned in the video food
stocks are declining. The
permafrost lake draining to the ocean and taking this freshwater fish supply,
is huge. Not only did it
remove the fish from the Island, that stock is officially gone because
freshwater fish cannot adapt to saltwater they will eventually die because they
cannot adjust to the ions. Anadromous
fishes such as salmon, that spend all or part of their adult life in salt water
and return to freshwater streams and rivers to spawn, and sometimes die after
returning, and now have no lake to return to.
For Anadronamous Fish see http://www.psmfc.org/habitat/edu_anad_table.html
The fish were food not only
for the people but for other fish, polar bears, seals, foxes, birds, it really
impacts the whole food chain, which is a huge concern. The lack of sea ice represents a
huge climate change, global warming has already hit the arctic. Without sea ice the seals have no
shelter to nurse their young, and seals require a lot of nursing and their milk
is very thick and rich in nutrients in order to build blubber which the seals
need to survive the harsh winters.
The Polar Bears need the Sea Ice to hunt the seals. The lemmings are gone and they were a
huge food source for foxes, which are hunted by the Inuit for their coat and
food, as are seals and polar bears.
