The book titled 'Environmental Laws and Sustainable Development in the Niger Delta, Nigeria" vividly describes the Niger Delta environment, the negative impact of exploitation of its natural resources, and the role of environmental laws in creating sustainable development in the region. The major themes in the book are international and domestic environmental laws, agencies for implementing environmental laws in Nigeria, sustainable development, contending issues in the Niger Delta region, and the challenges and roadmap for the application of environmental laws. These themes were thoughtfully selected based on current issues, such as environmental degradation, youth restiveness, and other illicit activities proliferating in the region. This book is relevant to all segments of society due to the interdependence between humans and the environment. Man, as a product of the environment, needs to be sensitised on the usefulness of the environment and the urgent need to protect it for sustainability.
