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.

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.
