The Pacific Garbage Patch is a massive accumulation of plastic debris in the Pacific Ocean. In the movie, the Persephone facility studies this environmental crisis, and the pollution directly connects to the creation of the three-headed shark. The film uses this real-world environmental issue as the catalyst for the monster's mutation and behavior.
