Great Pacific Garbage Patch, North Pacific Ocean

The Great Pacific Garbage Patch located between Hawaii and California is the largest accumulation of ocean plastic in the world


The Great Pacific Garbage Patch is a marine area in the Pacific Ocean between Hawaii and California with a high concentration of marine debris and plastic waste. The extent of the area is considered to be around 1,600,000,000 km2 and it is the largest and best known among other similar zones, some of which exist in the Atlantic and Indian oceans [1, 2, 3, 10]. A scientific article published in 2018 indicated that at least 79,000 tonnes of ocean plastic are floating inside this marine area [10].

The Conflict and the Mobilization
Intensity of Conflict (at highest level)MEDIUM (street protests, visible mobilization)
When did the mobilization beginIn REACTION to the implementation (during construction or operation)
Groups MobilizingInternational ejos
Local scientists/professionals
Forms of MobilizationArtistic and creative actions (eg guerilla theatre, murals)
Creation of alternative reports/knowledge
Development of a network/collective action
Development of alternative proposals
Involvement of national and international NGOs
Media based activism/alternative media
Public campaigns
Environmental ImpactsVisible: Biodiversity loss (wildlife, agro-diversity), Loss of landscape/aesthetic degradation, Surface water pollution / Decreasing water (physico-chemical, biological) quality, Large-scale disturbance of hydro and geological systems, Other Environmental impacts, Food insecurity (crop damage)
Potential: Global warming
OtherAdverse impacts on the entire marine ecosystem and marine food webs:

As micro plastics and other trash collect on or near the surface of the ocean, they block sunlight from reaching plankton and algae below. Algae and plankton are the most common autotrophs that are organisms producing their own nutrients from oxygen, carbon, and sunlight. If algae and plankton communities are threatened, the entire food web becomes endangered since most of marine animals such as fish and turtles feed on algae and plankton, which will than affect the predators such as tuna, sharks, and whales. Eventually, seafood would become less available in the marine ecosystem as well as more expensive for people. [3]
Health ImpactsPotential: Exposure to unknown or uncertain complex risks (radiation, etc…), Other Health impacts
OtherToxic impacts of micro plastics are identified even in the bodies of babies [11, 12].

Some plastics decompose within a year of entering the water, leaching potentially toxic chemicals such as bisphenol A, PCBs, and derivatives of polystyrene [11].
Socio-economic ImpactsVisible: Loss of livelihood
Potential: Other socio-economic impacts
OtherSeafood might become less available and more expensive [3].
Project StatusIn operation
Pathways for conflict outcome / responseGlobal awareness raising
Development of AlternativesThe environmentalists, international EJOs, and fisher people claim for the reduction and/or ban of (especially single use) plastics, and point to the need of reusing and recycling of plastics and materials.
Do you consider this as a success?No
Why? Explain briefly.The Great Pacific Garbage Patch is currently getting bigger and denser.
