Environmental nonprofit Sea Shepherd covers the outlines of sea animals in plastic film in a haunting short film and social campaign highlighting the topical issue of plastic pollution in the oceans.

Sea Shepherd worked with FF New York (formerly Fred & Farid) on the film, which is aimed at capturing the attentions of millennials on social media. It starts out as a mesmerizing, almost trippy colorful piece set to a dreamy music track, the kind of thing you might relax to in yoga — before gradually you realize that what you’re watching is animals such as a dolphin, turtle and shark trapped in plastic.

The spot aims to draw attention to the one million ocean animals that die each year due to plastic debris. It comes at a time when mainstream brands are starting to pay attention to banning single use plastic: for example, this week supermarket Waitrose in the U.K. banned its giveaway disposable coffee cups.
