Acid Test: The Global Challenge of Ocean Acidification


Acid Test: The Global Challenge of Ocean Acidification is a groundbreaking NRDC documentary, whcih explores the startling phenomenon of ocean acidification, which may soon challenge marine life on a scale not seen for tens of millions of years. The film, featuring Sigourney Weaver, originally aired on Discovery Planet Green.


Pollution from carbon dioxide is causing an increase in ocean acidity. In fact, our oceans have absorbed a quarter of all carbon dioxide emissions produced by burning fossil fuels since the Industrial Revolution. As a result, our oceans’ acidity levels have increase by 30%. Conditions like these have not existed since the extinction of the dinosaurs.

What does this mean to us and the marine species that inhabit our oceans? Will ocean species be able to adapt? How can we stop the rise of ocean acidity? Acid Test explores these issues, then reveals how to take action today to stop the creation of an uninhabitable ocean.
