  2. 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. 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.

  4. Marine debris - Wikipedia

    en.wikipedia.org/wiki/Marine_debris

    Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean.Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack.

  5. Marine plastic pollution - Wikipedia

    en.wikipedia.org/wiki/Marine_plastic_pollution

    Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic.

  6. Marine conservation - Wikipedia

    en.wikipedia.org/wiki/Marine_conservation

    Marine conservation is a relatively new discipline which has developed as a response to biological issues such as extinction and marine habitats change. Marine conservationists rely on a combination of scientific principles derived from marine biology, Ecology, oceanography, and fisheries science, as well as on human factors, such as demand for ...

    But this vital underwater habitat is in decline – with a loss of about 7% a year globally – due to factors like coastal development, climate change, overfishing and pollution.

  9. 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 ...
