Sigourney Weaver highlights threat from Ocean Acidification in Video Documentary

Just finished watching The Acid Test: The Global Challenge of Ocean Acidification short documentary on Ocean Acidification produced by the US based Natural Resources Defense Council (NRDC). It explains the issue and connection with global warming and climate change - but a little too simply for my preference - but the videography and production is excellent. 21:35 long. The actress Sigourney Weaver does the narration in this doco. For something a bit more in depth see marine chemist Dr Andrew Dickson from the Scripps Institute of Oceanography (56 min) presentation near the end of this article.
