Harmful Aspects of Plastic Carryout Bags

© Whale Rescue TeamThe indiscriminate littering of single use plastic carryout bags is an increasing blight problem.  Due to their expansive and lightweight characteristics, littered single use plastic bags are easily carried airborne by wind, where they end up entangled in brush, tossed around along freeways, and caught on fences.*

In addition, within the County's extensive and diverse watersheds, many littered single use plastic carryout bags find their way onto local beaches and eventually into the ocean, where they have been known to impact marine life that ingest them in the following unintended ways:

  • Clogging the throat, thus choking the animal.


  • Artificially filling the stomach so that the animal cannot consume food, depriving them of nutrients.


  • Infecting them with harmful toxins that can poison the animal.


  • Entangling the animal, leading to choking, cuts, and even restricting growth.*
Whales and large birds often swallow plastic carryout bags inadvertently during feeding, which become permanently lodged in the stomach.  Turtles swallow plastic carryout bags since they resemble their main food source, jellyfish.*

Recent studies indicate that littered plastics such as single use plastic carryout bags can transport, adsorb, and when ingested by animals, lead to the bioaccumulation of a variety of persistent organic pollutants. Marine animals that inadvertently ingest single use plastic carryout bags and other plastics are therefore subjected to numerous potential health impacts. In addition, plastic bags can smother plants, restricting growth and destroying the natural habitats of many different species of marine wildlife.*  

© Guardian News and Media Limited 2008Single use plastic carryout bags also affect domestic land animals, such as cows, goats, and horses, which occasionally eat plastic carryout bags found on the ground or entangled in brush.  Single use plastic bag litter is found to have similar undesirable health impacts on these animals.*

The North Pacific Gyre is an area located roughly 1,000 miles from the California coast line, where several ocean circular currents meet, creating an accumulation of marine debris, especially plastics.  Since plastics do not biodegrade, they often accumulate in the Gyre from multiple northern Pacific Rim countries.*
