Imagine A World Without Fish - No More Shrimp On The Barbie: With Ocean Acidification



Online Videos by Veoh.com

Ocean acidification remains an issue that print & broadcast media have only begun to pay serious attention to. Marine scientists are intensely focused on it, however. A movie about ocean acidification, currently in production, is fusing the scientific and mainstream cultural views of environment - after the fashion of Inconvenient Truth. Sea Change, a new documentary about ocean acidification will debute in the fall of 2008. Check out the trailer (above).Russ George, who has guested on TreeHugger recently regarding other effects of elevated atmospheric C02, comments about a recent up-tick in media coverage of ocean acidification research.

'While it is good to see this shocking news getting some attention, the worst-case potential is not fully reported... The studies being discussed focus on the role of acidification on adult ocean critters; but, where the impact really hits very much sooner and harder is in the larval forms of such things as Australian shrimps (for the barbie).'

Notably, in the face of the sustained, severe threat to marine life posed by ocean acidification, the International Union for Conservation of Nature (IUCN), regards proposals to mitigate ocean acidification directly as a "threat" to biodiversity.

Other emerging threats include those from iron and urea fertilization; other geoengineering schemes, for example to include pumps to bring colder and deeper waters to the surface, noise which can disrupt marine mammal cycles and may also effect fish behavior disrupting vibration patterns in the water column6.
Given that existing atmospheric carbon dioxide will continue to elevate ocean acidity, even if all ongoing emissions were stopped entirely, we have a long way to go to face the more significant "threat".

We are reminded by this of the Kübler-Ross model of humans coping with the threat of death [to the ocean in our analogy]. Perhaps the resistance to direct mitigation (anger bordering on outrage) will change once the USA takes a positive leadership role in reduction of carbon dioxide emissions.
