Plastic waste has become a menace in our society with a lot of increasing challenges every day. This paper examined plastic wastes and environmental deterioration in Sabon Layi Rusai area of Naraguta 'B', ward Jos, Plateau State. The objectives are to examine the sources of plastic waste and to proffer strategies for solving the problem of environmental deterioration in study area. The methodology employed for this study was physical observation, oral interview and the review of related literature. Purposive random sampling technique was used to identify 40 houses under the study area. It is a good recommended sample size because it reflects the population of the study. The study revealed that indiscriminate disposal of wastes from plastics and plastic products cause hazardous negative impact on the environment, such as air pollution from burnt plastics, sewage system blockage leading to flooding, and aesthetic defacement of the built environment. The study therefore recommends that sufficient awareness programmes on the dangers of plastic in the environment be organized; improvement in proper plastic waste collection, treatment and disposal, among others.
