Plastic pollution involves the accumulation of plastic products in the environment that adversely affects the wildlife,wildlife habitat, or humans. Plastics that as a pollutant are categorised as micro,meso, or macrodebris depending on size. Plastic pollution has increased since 1964,reaching 311million tones in 2014.It is expected to double again in 20 years and almost quadruple by 2050.
Microplastics are small plastic particles in the environment that are generally smaller than 1 mm (0.039 in) down to the micrometre range. They can come from a variety of sources, including cosmetics, clothing, and industrial processes.
Macroplastic is clearly visible plastic that can be caught, to say it in an easy way, and will not (with a few exceptions) have a direct impact on the food chain. Macroplastic degrades into microplastic due to different processes such as hydrolysis,photodegradation or mechanical/physical degradation
Marine debris and ‘marine’ litter are used interchangeably. UNEP defines marine litter as “any persistent, manufactured or processed solid. material discarded, disposed of or abandoned in the marine and coastal environment.
