The quality of the ecosystem is affected globally due to the large production, ubiquitous\u0000usage, and poor plastic waste disposal. Plastic debris is categorized based on its size as macroplastics, mesoplastics,\u0000microplastics, and nanoplastics, respectively. Microplastics are the emerging contaminant that occurs in varying\u0000shapes like tiny beads, spheres, films, fragments, fibres, and filaments. The use of microplastics in cosmetics and\u0000abrasion from large plastic items including textile fibres and tyres are suspected to contaminate the environment\u0000when it reaches the aquatic ecosystem. Indian coastal waters are polluted by microplastics owing to\u0000industrialization, overpopulation, tourist and maritime activities. Many species of fishes, reptiles, birds, and\u0000mammals are directly threatened by entanglement or ingestion, and some marine mammals consume a large\u0000amount of microplastic debris by raptorial feeding thereby leads to trophic transfer. Humans are considered as the\u0000most exposed organisms than other vertebrates as they occupy at the top of the food chain. Certain government\u0000legislations have been put forth to ban some products that are considered as the major contributor to plastic debris.\u0000Recently, the use of bioplastics is increased all over the world to replace microplastics in industrial and commercial\u0000products. However, there is little awareness of the microplastic pollutants among the public, thus the main motive\u0000of this review is to provide public awareness and responsibility to limit the use of plastics that adversely damage\u0000our environment","PeriodicalId":321881,"journal":{"name":"International Journal of Zoological Investigations","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130974667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
