Cultures have long heard wisdom in non-human voices: Apollo, god of music, medicine and knowledge, came to Delphi in the form of a dolphin. But dolphins, which fill the oceans with blipping and chirping, and whales, which mew and caw in ultramarine jazz - a true rhapsody in blue - are hunted to the edge of silence.
Australia is the only island continent on the planet, which means that changes caused by planet-warming pollution - warmer seas, which can drive stronger storms, and more acidic oceans, which wreak havoc on the food chain - are even more deadly here.
New flood maps in many states have raised the estimation of flood risks along rivers, streams and oceans, adding many properties to flood zones for the first time.
We need to do a better job of keeping oceans healthy.
We write for the same reason that we walk, talk, climb mountains or swim the oceans - because we can. We have some impulse within us that makes us want to explain ourselves to other human beings. That's why we paint, that's why we dare to love someone - because we have the impulse to explain who we are.
I love nature - it's probably my most favorite thing. I don't watch much telly, the telly hardly goes on, but the things I do watch are sort of nature programs, and something about the oceans and the amount of weird fish that's in there.
If you compare NASA's annual budget to explore the heavens, that one year budget would fund NOAA's budget to explore the oceans for 1,600 years.
Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.
People sometimes feel frustrated about what's going on in our oceans and environment, and 'Whale Wars' shows that ordinary people can take action and make things happen.
Our oceans have been the victims of a giant Ponzi scheme, waged with Bernie Madoff-like callousness by the world's fisheries.
