This book explains the causes, consequences and desirable solutions to the unbalanced and unfair relationship between Homo sapiens and the other species that inhabit Planet Earth in a succinct, enjoyable and thought-provoking way. Major sociological, economic, political, educational, religious and phylosophical perspectives are reviewed in order to understand why we have reached the current alarming status of global biodiversity during the Anthropocene, and how we can react to it to attain not just human welfare, but global happiness. The target audience is wide, from the general public interested in the deep inner causes of environmental degradation, to college and university students and lecturers, notably in the fields of environmental ethics, environmental philosophy, environmental law and environmental politics.
