Why is Marine Debris a Problem?
Plastic debris is especially threatening because of its ability to absorb and concentrate toxic pollutants.
Entanglement: Common items, such as fishing line or nets, strapping bands and six-pack rings, can hamper the mobility of marine animals. Once entangled, animals have trouble eating, breathing or swimming, all of which can have fatal results.

Ingestion: Birds, fish, and mammals often mistake plastics and other debris for food. Many endangered albatross birds and chicks have been found dead with stomachs full of plastic, including bottle caps and cigarette lighters. Sea turtles mistake plastic bags for jellyfish, one of their favorite foods. With debris filling their stomachs, animals have a false feeling of being full, and may die of starvation.
Disperse invasive species: Marine debris can provide suitable habitat for marine species, such as oysters, barnacles, or plants, to collect upon. As debris is carried away by the currents, so are the inhabitants. This process can potentially speed up the spread of invasive species.
Endanger human health: Beach visitors can be injured by harmful debris on beaches, such as broken glass and sharp metals. Toxic pollutants can also be transferred up the food chain and consumed by humans.
Hurt businesses and tourism: Increased amounts of debris on popular beaches can make beaches less attractive to visitors, resulting in a decrease in visitation and loss of money to the local community.
