Sigourney Weaver has lent her voice to another green documentary — this time one explaining the effects of excess atmospheric carbon on the oceans.
Called Acid Test, and produced by the Natural Resources Defense Council, the short film warns against ocean acidification and its effect on underwater food chain.

Set against stunning underwater scenery, Acid Test is worth 30 minutes of your lunch break to explore. Check it out below:
