As co-created by environmentalists Stephan Poulle and Nicolas Koutsikas, the documentary Gulf Stream and the Next Ice Age argues and provides evidence for the idea that mankind is wreaking permanent and potentially irreversible damage on the ecosystem by interfering with the natural course of the Gulf Stream. Koutsikas and Poulle suggest that this interference, in turn, will prompt a new Ice Age that virtually destroys the modern world.
