This book, on the subject of global environmental crisis and climate change that has threatened the very existence of humankind and the living system on planet Earth, claims that the current Anthropocene is the most dangerous era of environmental, and ecological crisis the planet Earth has ever witnessed. This book not only insightfully reflects upon the crisis manifested by climate change, breakdown of planetary ecosystem, extinction and annihilation of millions of species, acidification of oceans, desertification of productive lands, and toxic pollution attributing to the current dominant neoliberal economic model but also  presents a new ethical development framework that recognizes and promotes the instrumental, relational and intrinsic values in the Earth system which form the basis for social and environmental sustainability. This is a useful book for all stakeholders involved in environmental protection, UN, and development agencies, INGOs, civil societies, NGOs, governments officials and professionals, media personnel, universities faculties, students, and researchers.
