  2. Marine pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_pollution

    While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.

  3. Marine plastic pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_plastic_pollution

    Loss can occur during both the manufacturing and transport stages. [72] When released into the open environment, they create persistent pollution both in the oceans and on beaches. [73] About 230,000 tonnes of nurdles are thought to be deposited in the oceans each year, where they are often mistaken for food by seabirds, fish and other wildlife ...

  4. Marine mercury pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_mercury_pollution

    Mercury can enter seas and the open ocean as a result of the down stream movement and re-deposition of contaminated sediments from urban estuaries. [12] For example, high total Hg content up to 5 mg/kg and averaging about 2 mg/kg occur in the surface sediments and sediment cores of the tidal River Mersey, UK, due to discharge from historical industries located along the banks of the tidal ...

  5. Human impact on marine life - Wikipedia

    en.wikipedia.org/wiki/Human_impact_on_marine_life

    Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]

    Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...

  8. Garbage patch - Wikipedia

    en.wikipedia.org/wiki/Garbage_patch

    A garbage patch is a gyre of marine debris particles caused by the effects of ocean currents and increasing plastic pollution by human populations. These human-caused collections of plastic and other debris are responsible for ecosystem and environmental problems that affect marine life, contaminate oceans with toxic chemicals, and contribute ...

  9. Water pollution - Wikipedia

    en.wikipedia.org/wiki/Water_pollution

    Water pollution is a major global environmental problem because it can result in the degradation of all aquatic ecosystems – fresh, coastal, and ocean waters. [75] The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical changes
