Courtesy of Rozalia Project A separate small study in the Republic of Ireland released in June also found microplastic contamination in a handful of tap water and well samples.
Pollution of the Ocean by Plastic and Trash Pollution of the Ocean by Plastic and Trash Garbage has been discarded into the oceans for as long as humans have sailed the seven seas or lived on seashores or near waterways flowing into the sea.
Since the s, plastic use has increased dramatically, resulting in a huge quantity of nearly indestructible, lightweight material floating in the oceans and eventually deposited on beaches worldwide. As the graph shows, trash items encompass a variety of materials. Sources of marine debris include: Items that are brought to the beach and left there by beachgoers; Garbage deliberately or accidentally discarded by ships at sea or from offshore oil platforms; and Material carried to sea by rivers and estuariesespecially from large coastal cities.
City storm sewers are a significant source of solid waste entering the sea from land sources. Effects on Wildlife Aside from its unsightly appearance and potential impact to human health, marine debris has harmful effects on wildlife.
Fish, birds, marine mammals, reptiles, and other animals can become entangled in discarded or lost nets that continue to do what they were designed to do—catch living animals—but now they catch them indiscriminately, a process called "ghost fishing. Woven plastic onion sacks floating in the sea have entrapped endangered hawksbill sea turtles.
Plastic bags become invisible to birds diving for This graph shows the average number of trash items counted for several years along a popular 7-mile stretch of Mustang Island Gulf Beach, Texas. Beverage cans are single drink containers and include plastic bottles; chemical containers are 5-gallon pails and drums of chemicals; green bottles are bleach bottles from Mexico common on Texas beaches ; egg cartons and milk jugs are standard grocery items.
Plastic is also mistaken for food and is eaten at sea by birds, turtles, and even whales. This can choke them, poison them, or simply make them think they are full when this "food" has no nutritional value. Many marine animals get entangled in fishing lines used by recreational anglers.
Efforts to Reduce Debris Unsightly littered beaches gained public attention in the early s and efforts were made to find out how much garbage there was, where it came from, and what its effect was on ocean wildlife.
Medical waste and other floatable debris washing ashore at public beaches of the eastern United States, primarily in New York and New Jersey, was a particularly disturbing and highly publicized aspect of ocean pollution by municipal solid waste.
The incidents in New York and New Jersey spurred the passage of the federal Medical Waste Tracking Act which has since transferred to individual states as well as subsequent federal and state laws designed to better regulate the handling, treatment, transportation, and disposal of medical waste.
Since the early s, medical waste in U. However, Royal terns Sterna maxima are among several species of seabirds that dive from the air into the water to catch fish with their sharp beaks. A plastic bag floating at the surface would be invisible to the tern, and may even have attracted the fish in the first place.
In this photograph, the tern's bill penetrated the plastic and left the bird wearing the bag around its neck like a shroud. Scientists and environmental groups since the s have more closely addressed the problem of marine debris and its effect on public health and wildlife. The general public has helped in organized beach cleanups using data sheets to record the types and numbers of items found.
Cleanups were at first limited to beaches bordering the United States ocean coastlines, but soon international efforts were organized, and cleanups were also done along riverbanks, lakeshores, marinasand even by divers to recover submerged items along jetties and fishing piers.
Due in part to the public attention paid to marine debris, an international agreement MARPOL, or The International Convention for the Prevention of Pollution by Garbage from Ships; Annex V was reached by many of the world's governments to prohibit or limit the quantity of garbage that can be discharged at sea or in waterways that lead to the sea.
The United States ratified Annex V in In some areas like the Gulf of Mexico, there is a total ban on discharging plastics into the sea. All vessels must carry signs informing crews of the laws and must provide containers for different types of materials that will be offloaded at the next port of call rather than dumped into the sea.
Improving the general public's awareness, concern, and attitude towards littering; Reducing the use of plastic and other materials for disposable packaging; and Enforcing existing laws, especially at sea, to punish habitual litterers.
As the twenty-first century opened, marine debris continued to wash ashore on beaches around the world, including the United States.
There has been some reduction in the quantity of trash on America's ocean beaches, partly because of adherence to the law, partly because of self-imposed company rules, and partly owing to increased public awareness.
Much of the credit for this must be given to the beach cleanups that have given the public a first-hand look at the problem. Even so, marine mammals, reptiles, birds, and other ocean life continue to sustain injuries from ingesting or becoming entangled in plastic debris and fishing gear.Planet Ark is all about creating positive environmental actions, for everyone – but especially for you.
And the easiest way to learn about those actions is to subscribe to one or more of our e-newsletters. Tragically, research indicates that half of sea turtles worldwide have ingested plastic. New studies find plastic pollution is so pervasive on many beaches that its affecting their reproduction.
Hundreds of thousands of seabirds ingest plastic every year. Plastic fibres found in tap water around the world, study reveals leading to calls from scientists for urgent research on the implications for health.

The research into bottled water involved buying packs from 11 different global and national brands in countries chosen for their large populations or their relatively high consumption of bottled. The overwhelming majority of research conducted to date on plastic pollution (all size fractions) has focused on marine ecosystems.
In comparison, only a few studies provide evidence for the presence of plastic debris in freshwater environments. Plastic pollution is the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat and humans.
  Plastics that act as pollutants are categorized into micro-, meso-, or macro debris, based on size. .
