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 .
"Garbage that reaches the ocean from the west coast of the United States and from the east coast of Japan is carried by four main currents—including the California Current, the North Equatorial Current, the North Pacific Current, and the Kuroshio—into the North Pacific subtropical gyre, the clockwise rotation of which draws in and traps solid matter such as plastics. Some 80% of the plastics in the garbage patch come from the land. It takes years for debris to travel from the coasts to the gyre, and, as it is carried along, photodegradation causes the plastics to break down into tiny, nearly invisible bits. While there are some larger objects that come from ships and offshore oil rigs, the garbage patch incorporates mostly micro plastics." 
Even though scientifically it has been known since 1980s, it came to public attention mainly after 1997, when a sailor, Charles Moore, coincided with the sea of plastics on his route, which he revisited the following year and found that it was expanding and getting denser. Thus, the research foundation Algalita -that he had founded in 1994- began to engage with the marine litter problem. In 2006, a series of articles published in the Los Angeles Times about the garbage patch won a Pulitzer Prize and raised general awareness of the problem .
In 2015 and 2016, the Dutch-based organization Ocean Cleanup pointed out that the density of the debris in the garbage patch was much greater than expected and that the plastics absorbed pollutants, making them poisonous to marine life. 
The amount of debris in the Great Pacific Garbage Patch accumulates, and plastics make up the majority of marine debris for two reasons. First, due to plastic’s durability, low cost, and malleability, it has been used continuously more for industrial products and individual packaging for consumers. Second, plastic goods are not biodegradable but instead break down into smaller pieces. Additionally, the seafloor beneath the Great Pacific Garbage Patch may also be an underwater trash heap. Oceanographers and ecologists recently discovered that about 70% of marine debris actually sinks to the bottom of the ocean.
The amount of plastics in oceans impact the entire marine ecosystem and marine food webs. Seals and other marine mammals are especially at risk. They can get entangled in abandoned plastic fishing nets, which are being discarded more often because of their low prices.
Moreover, 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, i.e. organisms that can produce their own nutrients from oxygen, carbon, and sunlight. If algae and plankton communities are threatened, the entire food web gets adversely affected. Animals that feed on algae and plankton, such as fish and turtles as well as predators such as tuna, sharks, and whales will have less available food. Eventually, nutrition in the entire marine ecosystem and seafood for people will be less available as well as more expensive for people. 
There have been several international awareness raising campaigns especially since 2017. One example is a French anti-plastic campaigner, Ben Lecompte, who has begun a swimming route of 8,000 km on 5th of June, 2018 between Japan and San Francisco, which will be passing through the Great Pacific garbage patch . Another instance is the creation of a large catamaran out of plastic bottles: the Plastiki. The sturdiness of the Plastiki displayed the strength and durability of plastics, the creative ways that they can be repurposed, and the threat they pose to the environment when they do not decompose. In 2010, the crew successfully navigated the Plastiki from San Francisco, California, to Sydney, Australia .
Scientists and ecologists agree that limiting and/or eliminating the global use of disposable plastics and increasing the use of biodegradable resources will be the best way to clean up the Great Pacific Garbage Patch. Organizations such as the Plastic Pollution Coalition and the Plastic Oceans Foundation are using social media and direct action campaigns to support individuals, manufacturers, and businesses in their transition from toxic, disposable plastics to biodegradable or reusable materials .
However, some organisations like Plastic Pollution Coalition also underline that plastic pollution is an environmental and social justice issue and that fence line communities are most adversely affected by it at every stage of its life cycle. Thus, they have initiated campaigns in order to reject single-use plastics . Moreover, it had already been investigated that the marine debris, especially plastic debris are negatively affecting traditional fisher communities .
Even though there have been projects and initiatives, in which fisher people engaged with collection of plastics and garbage from the sea [15, 16, 17, 18, 19, 20, 21], it is obvious that without stopping the use of (especially single-use) plastics, and growing use of materials in global economies, such huge and global environmental justice problems cannot be solved.
