The critical but largely unknown problem of ocean acidification 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, believe that it’s possible to cut back on pollution causing global warming, 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. Narrated by Sigourney Weaver.
