Plastic pollution is the accumulation of plasticproducts in the environment that adversely affects wildlife, wildlife habitat and humans.[1][2] Plastics that act as pollutantsare categorized into micro-, meso-, or macro debris, based on size.[3] Plastics are inexpensive and durable, and as a result levels of plastic production by humans are high.[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 have led to a high prominence of plastic pollution in the environment.
Plastic pollution can afflict land, waterways and oceans. Living organisms, particularly marine animals, can be harmed either by mechanical effects, such as entanglement in plastic objects or problems related to ingestion of plastic waste, or through exposure to chemicals within plastics that interfere with their physiology. Humans are also affected by plastic pollution, such as through disruption of various hormonalmechanisms.
As of 2018, about 380 million tonnes of plastic is produced worldwide each year. From the 1950s up to 2018, an estimated 6.3 billion tonnes of plastic has been produced worldwide, of which an estimated 9% has been recycled and another 12% has been incinerated.[6] In the UK alone, more than 5 million tonnes of plastic are consumed each year, of which only an estimated one-quarter is recycled, with the remainder going to landfills.[citation needed]. This large amount of plastic waste inevitably enters the environment, with studies suggesting that the bodies of 90% of seabirds contain plastic debris.[7][8] In some areas there have been significant efforts to reduce the prominence of plastic pollution, through reducing plastic consumption and promoting plastic recycling.[9]
Some researchers suggest that by 2050 there could be more plastic than fish in the oceans by weight.[10]

പ്ലാസ്റ്റിക് മലിനീകരണം എന്നത് പ്ലാസ്റ്റിക് വസ്തുക്കളുടെ സംഭരണമാണ് (ഉദാ: പ്ലാസ്റ്റിക് കുപ്പികൾ, അതിലധികവും) വന്യജീവികൾ, വന്യ ജീവികൾ, മനുഷ്യർ എന്നിവയെ പ്രതികൂലമായി ബാധിക്കുന്ന ഭൂമിയുടെ അന്തരീക്ഷത്തിൽ. മലിനീകരണമെന്ന നിലയിൽ പ്രവർത്തിക്കുന്ന പ്ലാസ്റ്റിക്ക്, വലുപ്പത്തെ അടിസ്ഥാനമാക്കി, മൈക്രോ, മീസോ, അല്ലെങ്കിൽ മാക്രോ അവശിഷ്ടങ്ങൾ ആയി തരം തിരിച്ചിരിക്കുന്നു. പ്ലാസ്റ്റിക്കുകൾ വിലകുറഞ്ഞതും മിതവുമാണ്, ഫലമായി മനുഷ്യരുടെ പ്ലാസ്റ്റിക് ഉത്പാദനത്തിന്റെ അളവ് വളരെ കൂടുതലാണ്. എന്നാൽ മിക്ക പ്ലാസ്റ്റിക്കുകളുടെയും കെമിക്കൽ ഘടന അവരെ പല തരം പ്രകൃതിദത്ത പ്രക്രിയയെ പ്രതിരോധിക്കും, തത്ഫലമായി അവ മന്ദഗതിയിലാകും. [5] ഈ രണ്ടു ഘടകങ്ങളും പരിസ്ഥിതിയിൽ പ്ലാസ്റ്റിക് മലിനീകരണത്തിന്റെ ഉയർന്ന പ്രാധാന്യം നൽകുന്നു.
