In 2009, I worked as a volunteer for 8 months with local communities in the Ha'apai Islands of Tonga. We motivated over 3,000 locals (from a total population of 4,500) to remove 50 tonnes of rubbish in a one-day island-wide clean-up.
Days later, we were lucky enough to be taken out into the ocean on a sailboat and get in the water with a humpback whale and her calf.
It was an unforgettable experience - they stayed with us for over an hour, completely relaxed. Our guide was in tears, despite having spent 10 years doing this, as it was so special. It actually felt like they were thanking us for the months of hard work.
Last night the New Zealand whale watching industry and conservationist groups got the welcome news that the International Court of Justice in the Hague has ordered Japan to stop whaling in the Southern Ocean.
This has occurred "with immediate effect" and left the hard-core activists - like Sea Shepherd (who's boat the Bob Barker was in Wellington last week) and Pete Bethune who have been fighting whaling, feeling vindicated.
I still find it amazing that this took so long to happen.
