How does plastic trash cause marine life and sea birds to starve?

• They mistake plastic for food, which clogs their stomachs and doesn't leave any room for real food.

• Plastic takes up space in the water so marine animals have no place to live.

• The plastic in the ocean is so dense that the marine life cannot find food easily.

• Plastic doesn't cause marine life or sea bird to starve: they're smart enough to know the difference between plastic and food.

• The tiny plastic particles in the ocean end up coming through the faucets in our sinks once the salt water is converted to fresh water.

• The fish in the ocean eat the plastics and humans eat the fish, causing the toxic chemicals from the plastics to spread from the fish to humans.

• Humans are mistaking plastics in the ocean for food just as the marine life and sea birds are.
