“A Sea Change – Imagine a World Without Fish” is a recently released documentary film about ocean acidification, the little-known ugly sister of global warming. The film website www.aseachange.net explains it “… aims not only to educate viewers about the science of our rapidly-changing oceans, but also to engage them on accessible terms.”
The full film was shown to the European Geosciences Union 2009 conference on 27 April 2009, a podcast of which is available here. After a 2 minute introduction, the film lasts for 19 minutes followed by an illuminating question and answer session.
