This book presents the current aspects of environmental issues in view of chemical processes particularly with respect to two facets: social sciences along with chemistry and natural sciences. The former facet explores the environmental economics and policies along with chemical engineering or green chemistry and the latter the various fields of environmental studies.

The book was conceptualized in the form of e-learning content, such as Power Point presentation, with explanatory notes to a new style of lectures on environmental science in a university at undergraduate level. Each chapter of the book comprises a summary of the contents of the chapter; a list of specific terms and their explanation; topics that can be taken up for discussion among college students, mainly freshmen in liberal arts, and for enhancing general knowledge; and problems and solutions using active learning methods.
