Each year some humpback whales migrate from the Antarctic to north eastern Australian waters travelling a distance of some 10,000 Kilometres. Some pass Sydney and even enter the harbour.
I understand there is lots of food in the Antarctic, but it's a bit cold for birthing with baby whales likely to freeze in Antarctic water.

Hi Libby and Marcus,
This is interesting stuff... firstly as Libby and Marcus that point out that over-exaggerating numbers won't help the cause and secondly the issue in itself re litter.
I wrote this on my own blog:
" On Jennifer’s blog , Marcus wrote that my statement that ” millions of sea birds and 100 000 marine animals died of plastic debris” was without proof.
Here’s a link:
http://www.savethenorthsea.com/documents/Kampanjer-och-aktiviteter/Save-the-North-Sea/Fast_facts_about_marine_litter.pdf
that claims that over 1 million sea birds die of plastic litter.
Other sources have claimed as well that MILLIONS of sea birds are in danger of plastic debris.
Of course the real numbers are unknown, as Veterinary authorities are not keen on to make an autospy on every dead bird , as they themselves have pointed out.

It certainly is a case that most birds don't get autospied ( only the interesting cases and not just a common dead sea gull on the beach). Veterinary Institute has personally told us not to please to come to them with every single dead animal.... so the real numbers re plastic litter casualities are unknown.
