English for Academic Purpose 1The small particles of plastic present in the environment coming from a variety of sources such as clothing, cosmetics and industrial process are known as microplastics. Primary microplastics (direct result of human product and material use) and secondary microplastics (microscopic plastic fragments) persist in high levels in the environment, mainly in marine and aquatic ecosystem. Plastics do not break down for a number of years and this is the major reason behind their ingestion, incorporation and accumulation in the tissues and bodies of various organisms. Complex mixture of chemicals are associated with microplastics that increase their chances of getting transferred to the human body or other organisms upon exposure. These microplastics enter the human body via consumption of food such as fish and significantly impact the health ofthe humans.The prevalence of microplastics is increasing in the seas and oceans, soils, inland waters, inland and outdoor air and food web. There are far reaching societal benefits of plastic but on the other hand this valuable commodity has resulted in becoming a subject matter of increasing environmental concern. There are several causes of the presence of microplastics in the environment. The durability of plastic is the reason which makes it highly resistant to degradation which further creates problems in the disposing of waste plastic. Only a small part ofthe plastic waste is recycled and the major part ends up in landfill where it takes centuries for breaking down and decomposition. Such plastic enters the marine environment in the end (Cole, Lindeque, Halsband & Galloway, 2011).Furthermore, the presence of microplastics in the environment is also the result of clothing consisting of synthetic fibres. Polyester and acrylic shed off their tiny fibres at the time of washing. Fibres cannot be removed even by the facilities that treat waste water allowing them to reach the oceans. Microplastics are also present in the environment i.e. oceans in the form of granules or pellets also known as nurdles which are largely utilized by manufacturers for the purpose of manufacturing plastic items. These are also by the marine animals by assuming them as prey. Also, plastic particles are also present in the products for the purpose of enhancing their cleaning ability and abrasiveness such as soaps, toothpastes, facial scrubs and facial cleansers (Crampton, 2017). These microplastics also adversely impact the environment by impacting in sentinel species, ecosystems and population, trophic transfer in food webs and accumulation,
