An estimated one percent of thrown-away plastic bags never make it to the landfill. Instead, they become street litter which first gets washed into the city's storm drains and then, should a heavy rain come and overflow the system, gets dumped through a harbor estuary. In that case, the bags head straight to the ocean where they become accidental food for the seven species of sea turtle, 300 species of fish, 350 species of bird, 10 species of whale and several species of seals and porpoises who live there. This video tells us the story of how a plastic bag carries itself across the world.
