ACID TEST, a film produced by NRDC, was made to raise awareness about the largely unknown problem of ocean acidification, which poses a fundamental challenge to life in the seas and the health of the entire planet. Like global warming, ocean acidification stems from the increase of carbon dioxide in the earth’s atmosphere since the start of the Industrial Revolution.

Leading scientific experts on the problem, many of whom appear in the film and the outtakes below, believe that it’s possible to cut back on global warming pollution, improve the overall health and durability of our oceans, and prevent serious harm to our world, but only if action is taken quickly and decisively.

The film originally aired on Discovery Planet Green. An Entertainment Industry Foundation grant provided the core funding for this film. Cinematographers Howard and Michele Hall and Nel Boshoff provided footage, and many other people assisted greatly in the making of ACID TEST.

Scientist Steve Palumbi discusses what’s at stake, and Ken Caldeira explains how this is not just an economic issue, but also a moral one. Both men talk about their frustration that we don’t seem to be doing enough to prevent this catastrophe.
