Chlorinated plastics releases harmful chemicals and toxic substances into the surrounding soil, which can then seep into ground water or other surrounding surface water bodies in the form of a black thick liquid known as leachate causing sever water pollution. This water, if used as drinking water, causes serious harm to both plants and animals. Many advanced polymer composites used in various fields can leach into water forming hurdles. Plastic pollution is potentially poisonous to animals, which can then affect human food supplies. Plastic materials contain a number and variety of chemicals that are carcinogenic and mutagenic in nature. The five R's (recycle, reuse, reduce, remove, and refuse) can control the plastic pollution in our environment. This chapter explores plastic pollution and its effect on the environment.
