 The UN conference in Paris was attended by 150 Heads of State and Government from around the world, as well as by 117 ministers responsible for international climate negotiations. Some of these treaties are administrative in their nature and not immediately visible because some results will come up later, in a few years.

 While there is some contention over their size, the U.S. National Oceanic & Atmospheric Administration classifies micro plastics as less than 5 mm in diameter. In: Arthur, C., J. Baker and H. Bamford in International Research Workshop on the Occurrence, Effects and Fate of Microplastic Marine Debris. University of Washington Tacoma, Tacoma, WA, USA, 2008.
 Two classifications of micro plastics currently exist: primary micro plastics are manufactured and are a direct result of human material and product use (like shampoo, cosmetics and scrubbers), and secondary micro plastics are microscopic plastic fragments derived from the breakdown of larger plastic debris.

Five vast areas of Open Ocean, known as the subtropical gyres, act as a trap for ocean plastic. We specifically focus on the North Pacific accumulation zone - also known as ‘the Great Pacific Garbage Patch’ - since about 1/3 of all oceanic plastic is concentrated in that one area between Hawaii and California (Cózar et al., 2014)”.

 From the Eunomia report  this quote; ‘The main contributor is larger plastic litter, including everyday items such as drinks bottles and other types of plastic packaging. Primary micro-plastic emissions also have an important role. The remainder comes from plastics released at sea, the majority as a result of fishing activities – for example, due to lost and discarded fishing gear. 94% of the plastic that enters the ocean ends up on the sea floor. There is now on average an estimated 70kg of plastic in each square kilometre of sea bed. Barely 1% of marine plastics are found floating at or near the ocean surface, with an average global concentration of less than 1kg/km2. This concentration increases at certain mid-ocean locations, with the highest concentration recorded in the North Pacific Gyre at 18kg/km2. By contrast, the amount estimated to be on beaches globally is five times greater, and importantly, the concentration is much higher, at 2,000kg/km2. While some may have been dropped directly, and other plastics may have been washed up, there is a ‘flux’ of litter between beaches and the sea’.
