How beautiful bioluminescent bacteria can expose invisible water pollution

By journeying to the depths of the ocean to study bioluminescent sea creatures, Edie Widder, president of the Ocean Research and Conservation Association in Florida, has witnessed firsthand the strange, vibrant colours of deep-sea life. In a stroke of inventive inspiration, Widder has taken her work with bioluminescent life and applied it to the ongoing problem of invisible pollution, which is putting the world’s oceans and waterways in peril. A short documentary by the Academy Award-winning director Alex Gibney, Speaking With Light is a meditation on hidden problems, inventive solutions and beautifully simple science.
