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.
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]
The history of environmental pollution traces human-dominated ecological systems from the earliest civilizations to the present day. [1] This history is characterized by the increased regional success of a particular society, followed by crises that were either resolved, producing sustainability, or not, leading to decline.
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 ...
The 2017 United Nations Ocean Conference was a United Nations conference that took place on 5-9 June 2017 which sought to mobilize action for the conservation and sustainable use of the oceans, seas and marine resources. [1] [2] [3]
The Great Pacific Garbage Patch formed gradually as a result of ocean or marine pollution gathered by ocean currents. [39] It occupies a relatively stationary region of the North Pacific Ocean bounded by the North Pacific Gyre in the horse latitudes. The gyre's rotational pattern draws in waste material from across the North Pacific ...
In solidarity with the annual UN themes, The Ocean Project launched a five-year Conservation Action Focus on plastic pollution prevention and helping with solutions for a healthy world ocean. The World Ocean Day Youth Advisory Council launched in 2016, and current cohort includes 25 diverse young leaders (ages 15–23) from 22 countries. [8]
The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
