The Lost Continent - A Reinterpretation of Dennis Wheatley's "Uncharted Seas"

The bedouins where washed up at the shores of the North Atlantic Plastic Patch some time ago. As they couldn't leave, they made with what they managed to get: Rain water for drinking, fishes and algae for food, and crude oil for fire and energy.

A different approach to the "Uncharted Seas" and the Hammer movie adaptation "The Lost Continent". I think the plastic doesn't need to be alive to be hazardous.
