Answer:

Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects wildlife, wildlife habitat, and humans.[1][2] Plastics that act as pollutants are categorized into micro-, meso-, or macro debris, based on size.[3] Plastics are inexpensive and durable making them very adaptable for different uses; as a result levels human produce a lot of plastic.[4] However, the chemical structure of most plastics renders them resistant to many natural processes of degradation and as a result they are slow to degrade.[5] Together, these two factors allow large volumes of plastic to enter the environment as mismanaged waste and for it to persist in the ecosystem.

Plastic pollution can afflict land, waterways and oceans. It is estimated that 1.1 to 8.8 million tonnes of plastic waste enters the ocean from coastal communities each year.[6] It is estimated that there is a stock of 86 million tons of plastic marine debris in the worldwide ocean as of the end of 2013, with an assumption that 1.4% of global plastics produced from 1950 to 2013 has entered the ocean and has accumulated there.[7] Some researchers suggest that by 2050 there could be more plastic than fish in the oceans by weight.[8] Living organisms, particularly marine animals, can be harmed either by mechanical effects, such as entanglement in plastic objects, problems related to ingestion of plastic waste, or through exposure to chemicals within plastics that interfere with their physiology. Degraded plastic waste can directly effect humans through both direct consumption (i.e. in tap water), indirect consumption (by eating animals) and disruption of various hormonal mechanisms.
