What is ocean pollution
What Has Been Done? The sum of those values divided by 3 the the maximum pressure-goal value expresses the total affect of that pressure on the goal.

But the failure of public municipal waste infrastructure is the primary source of chronic levels of marine debris near coastal megacities in Asia. Samples of sea sand and seawater collected from Europe, India, Japan and the Pacific Ocean were found to be contaminated, with up to parts per million of some of these components of plastic decomposition. It is estimated that of the 1. Education, Legislation, and Awareness The starting point of all greater good does remain education and information. Icelandic shore.
Furthermore, in some areas where marine debris concentrates so does marine life, such as in the STCZ. Auman, J. Bythat number jumped to The Aggressors The obvious and simple answer is: us… Behind each and every piece of littered plastic debris there is a human face. They have been linked to the masculinisation of female polar bears and spontaneous abortions and declines in seal populations.
It has been discovered that the majority of the plastic ends up in the ocean through rivers, especially seven rivers in Asia, Bonnie Monteleone, oceans plastic researcher at the University of North Carolina at Wilmington and executive director of the Plastic Ocean Project, told ABC News.
Marine trash is a pressure for several of the Ocean Health Index goals. They are: plastic cigarette butts, food wrappers, plastic beverage bottles, plastic bottle caps, and plastic straws and drink stirrers. Inour global plastic consumption worldwide has been estimated at million tons, and, according to a report by Global Industry Analysts, plastic consumption is to reach Fact 7: There is an island of garbage twice the size of Texas inside the Pacific Ocean: the North Pacific Gyre off the coast of California is the largest oceanic garbage site in the entire world.
It is believed that this made it difficult for the animal to forage and feed effectively.

Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic or getting entangled in it.

Chemical pollution Chemical pollution is the introduction of harmful contaminants. In , twenty containers full of rubber ducks were lost overboard from a ship traveling from China to Seattle. Among the most seriously affected are coastal communities increased expenditures for beach cleaning, public health and waste disposal , tourism loss of income, bad publicity , shipping costs associated with fouled propellers, damaged engines, litter removal and waste management in harbors , fishing reduced and lost catch, damaged nets and other fishing gear, fouled propellers, contamination , fish farming and coastal agriculture. Polypropylene PP — Used in ketchup bottles, yogurt and margarine tubs, medicine and syrup bottles, straws, and Rubbermaid and other opaque plastic containers, including baby bottles. It has been strongly linked to asthma and allergies in children. Navy for testing and training causes some of the same effects—and has been linked to mass whale strandings , too. Environmental Protection Agency asking the government to regulate plastics as a pollutant under the Clean Water Act and will keep pushing for plastic pollution to be treated as the hazardous waste that it is. DEHP is an endocrine disruptor that mimics the female hormone estrogen. Unnatural noises interrupt communication , disrupting migration, communication, hunting, and reproduction patterns for many marine animals. The amount of plastic in the Atlantic Ocean has tripled since the s. The Center has petitioned the Environmental Protection Agency to begin regulating plastics as a pollutant and is working to stop plastic pollution at the source, before it ever has a chance to reach the ocean.

An estimated fourth fifths of the oceanic debris is litter blown seaward from landfills and urban runoff washed down storm drains.
In essence, humans are eating their own waste. InRyan et al obtained evidence that PCBs in the tissues of Great Shearwaters were derived from ingested plastic particles from Derraik,
