Shining a light on pollution

Many marine organisms have evolved to exhibit bioluminescence – putting on incredible deep sea displays of flashing lights, sparkling blooms and smoke-like clouds of shimmering blue.

Inspired by this magnificent spectacle, marine biologist Dr Edith Widder has developed a way to use bioluminescent bacteria to help protect our aquatic environments.

Some of the most insidious forms of modern-day pollution are not visible to the naked eye, especially those which contaminate our oceans. By mixing bioluminescent bacteria with sediment samples, Dr Widder uses these tiny organisms as bioindicators of toxins in marine and riverine environments. Using the light these sea creatures produce we are better able to reveal the source and severity of pollution in our waterways.

Directed by Alex Gibney, this film was originally featured in the Focus Forward series, which explores innovative people who are reshaping the world through act or invention.
