FOREWORDDuring my career as a documentary cameraman I have filmed on every continent on Earth, from the Serengeti to Siberia, the slopes of Everest to the underwater canyons of Kaikoura, and the Ross Sea is without doubt one of the most amazing places I have been to. It has the most productive waters in the entire Southern Ocean and teems with life, with many species found nowhere else on the planet.
What makes this remote corner of our world special is that it is the most untouched and intact marine ecosystem left on Earth. It is one of the last places where you can see the top predators, including large fish, whales, seals and penguins in natural numbers. Scientists refer to the Ross Sea as a living laboratory, a place that can teach us about the workings of all marine ecosystems.
The fishing industry has recently found its way to the Ross Sea. In 1996 New Zealand initiated an Antarctic toothfish fishery which now plans to reduce the adult population of toothfish by 50% over 35 years. We know from experience in every other ocean on Earth, that when you remove a top predator from an ecosystem it will have wide reaching impacts. Remove the toothfish and the natural balance of the Ross Sea ecosystem will be lost forever. This raises the simple ethical question: do we fish the last ocean or do we protect it?
With rapid environmental change taking place across the globe, it’s vital that we inform our young people about what is happening in the world and engage them to think critically about issues and how they are reported.
The Last Ocean documentary was completed in July 2012. Used alongside this education resource, we hope to provide a tool for teachers and students that not only celebrates the remarkable animals of the Ross Sea ecosystem, but also explores the business, politics and values that affect this precious and important part of the world.
Peter YoungDirector, The Last Ocean documentaryCo-Founder, The Last Ocean Charitable TrustNovember15,2012
The Last Ocean Charitable Trust was established in Christchurch in August 2009, to raise awareness about the pristine qualities of the Ross Sea Antarctica and promotes the establishment of a Ross Sea marine protected area.
