Impacts on marine ecosystems The most visible impacts of plastic debris are the ingestion, suffocation and entanglement of hundreds of marine species. Marine wildlife such as seabirds, whales, fish and turtles mistake plastic waste for prey; most then die of starvation as their stomachs become filled with plastic.

How do plastic bags harm animals?
Plastic in an animal's gut can prevent food digestion and can lead to a very slow and painful death. As plastic bags can take up to 1,000 years to break down, once an animal dies and decays after ingesting plastic, the plastic is then freed back into the marine environment to carry on killing other wildlife.
Why is plastic so harmful to animals in the ocean?
Sea animals often eat microplastics because of their small size. And plastic contains toxic chemicals, which can increase the chance of disease and affect reproduction. After ingesting microplastics, seals, and other animals, may suffer for months or years before they die.
How does plastic affect coral reefs?
In areas polluted by plastic, corals are more susceptible to disease development. Contact between debris and corals could cause physical injury to coral tissues and thus promote their infection by bacteria present on plastic debris. This study highlights the importance of combating plastic pollution in the oceans.
How does plastic get into the ocean?
Wastewater, wind, rain and floods also carry plastic from the land into the oceans, especially single-use plastics — bags, straws, cotton buds or wrappers — which, being lightweight, are easily carried on the wind to the coast or find their way to the river network before reaching the sea.
How does marine pollution affect marine life?
This sharp increase in plastic entering our waters harms not only marine life but also humanity. Plastic kills fish, birds, marine mammals and sea turtles, destroys habitats and even affects animals' mating rituals, which can have devastating consequences and can wipe out entire species.
How does plastic affect the ocean facts?
Marine plastic pollution has affected 100% of marine turtles, 59% of whales, 36% of seals and 40% of seabirds of those examined. Over 1 million seabirds and 100,000 marine mammals are killed by ocean plastic every year. 700 species of marine animals are in danger of extinction due to plastic.
How do plastic bags affect the environment?
The Problem With Plastic Bags. Plastic bags start out as fossil fuels and end up as deadly waste in landfills and the ocean. ... This means more plastic in our oceans, more greenhouse gas emissions and more toxic air pollution, which exacerbates the climate crisis that often disproportionately affects communities of color.
How does plastic pollution affect the Great Barrier Reef?
Marine debris is a major threat to the health of the Great Barrier Reef and kills marine life such as turtles, dugongs, dolphins and seabirds. ... More than 80 per cent of marine debris found in the Reef is plastic, which can break up into smaller pieces and travel vast distances, increasing the risk of impacts.
How is plastic pollution affecting the biodiversity on the coral reef?
It is well known that marine plastic pollution harms ocean life, including many species found in Cambodian waters. ... Plastic bags and nets can smother or even kill corals—the cornerstones of marine ecosystems—with recent research also showing that exposure to plastic particles increases coral disease outbreaks.
How much plastic bags end up in the ocean?
In total, we use 100 million tons of plastic every year. Some 10 percent of this plastic end up in the oceans. An estimated 300 million plastic bags every year end up in the Atlantic Ocean alone. All that plastic ending up in oceans is not without consequences.
What is killing marine life?
Sewage carries bacteria and viruses that are harmful to humans and it also can sicken and kill marine life, including corals. ... Finally, marine debris, or trash, strangles, starves and even kills marine animals such as sea turtles and birds. Plastic bags, for example, can be mistaken for food and eaten by sea turtles.
What are harmful effects of plastic?
Chemicals in plastic-like lead, cadmium and mercury directly can come in contact with the humans. These toxins can cause cancers, congenital disabilities, immune system problems and childhood development issues. The other toxins like BPA or health-bisphenol-A are found in plastic bottles and food packaging materials.
How does rubbish affect coral?
Across the study region, researchers found that the presence of plastic rubbish increased the odds of corals getting sick—by a lot. Coral reefs from places contaminated with plastic had an 89% chance of developing a disease. In plastic-free regions, these odds were just 4%!
What are the impacts of marine debris?
Marine debris can injure or kill marine and coastal wildlife; damage and degrade habitats; interfere with navigational safety; cause economic loss to fishing and maritime industries; degrade the quality of life in coastal communities; and threaten human health and safety.
How does marine debris affect coral reefs?
Trash such as plastic bags, bottles, and discarded fishing gear (also called marine debris) that makes its way into the sea can snag on corals and block the sunlight needed for photosynthesis, or entangle and kill reef organisms and break or damage corals.
