Plastics refer to a broad category of synthetic or semi-synthetic materials that contain polymers as their primary component. They can be extruded, molded or pressed into solid objects of diverse shapes due to their plasticity. They are accumulated extensively in natural ecosystems due to their durability, improper waste management and irresponsible use. They do not degrade naturally and pollute natural ecosystems, such as oceans and rivers. Plastics of all sizes, shapes as well as origins are widespread in the marine environment a negative have an impact on a variety of marine species that ingest or become entangled in plastics. This book provides significant information of this subject to help develop a good understanding of the current status and challenges related to the management of plastics in the aquatic environment. It presents the complex subject in the most comprehensible and easy to understand language. Those in search of information to further their knowledge will be greatly assisted by this book.
