I listen to marine scientist Rob King (centre) explain the dangers of acidification. Australian National Maratime Museum, Sydney, 15 November 2009
Australian Antarctic Division marine scientist, Rob King, understands the dangers of increasing acidification of world oceans. It's the children who need to understand the science, says Rob, so they can educate their parents, and do things differently. Not many people know about acidification, he says, and yet this is of more immediate concern than the huge problem of sea levels rising.
Krill are key to the health of the ocean's ecosystem. Normal krill development is threatened by acidification.
To help to communicate his knowledge, Rob displays the animations How do krill grow?, and Krill watching, during his 2009 tour with Polar Palooza.
Between these presentations, he shows live krill and a two million year-old ice core from Antarctica.
