Plastics are integral part of the society and have varied application. They are composed of a network of molecular monomers bound together to form macromolecule (polymers). A polymer may contain additives like plasticizers, stabilizers, lubricant, UV absorbing material, flame retardants to improve performance. The rise of plastics since the mid 20th century, both as a material element and also as a growing environmental pollutant, has been widely described. Plastic pollution represents one of the most significant environmental problems facing mankind. There is massive accumulation of plastic debris and its degradation products in marine ecosystems. A large number of marine species is known to be harmed or killed by plastic debris. Marine animals are mostly affected through entanglement and ingestion of plastic litter. The plastic ingestion is increasing in sea birds that will reach 99% of all species by 2050. Waste water treatment plants have been identified as a potential source of microplastics. Plastics are widely dispersed in sedimentary deposits and their amount likely to grow several folds over the next few decades. Enhancement of the ecological consciousness through education, a proper legislation, and effective waste management systems can be the best way to solve such environmental problem.
