Currently, it is estimated that there are 100 million tons of plastic in oceans around the world.Information About Sea Turtles: Threats from Marine Debris. The Problem: Over 1 million marine animals (including mammals, fish, sharks, turtles, and birds) are killed each year due to plastic debris in the ocean. Currently, it is estimated that there are 100 million tons of plastic in oceans around the world.100,000 marine creatures a year die from plastic entanglement and these are the ones found. Approximately 1 million sea birds also die from plastic. A plastic bag can kill numerous animals because they take so long to disintegrate.Sea turtles are eating ocean plastic because it smells like food, study finds.
