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.
Humans are also ingesting plastic that has ended up in the ocean. How is this possible.
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.
All of the above.
