The book combines a state-of-the-art review of current knowledge of plastics' harms to human health and the global environment with an exploration of the social consequences and the ethical foundations of the plastics crisis. The book gathers contributions of scientists, ethicists, economists, policy makers, and religious leaders. The plastics crisis is more than an environmental threat, and like climate change, air pollution, biodiversity loss, and escalating inequality, it is also a social and ethical challenge. It is a crisis that demands solutions that are based on the best science but that are also just and ethically sound.
