This book explores the human relationship to changing biodiversity by bringing together multidisciplinary insights into human-nature relations from the humanities. New animal and plant species arrive and previously existing ones may disappear. However, the historical and social perspectives of the changes have been understudied so far. This book approaches the human relationship with changing biodiversity from three different angles: belonging and non-belonging, emotions, and environmental policy. The question of belonging and non-belonging is crucial when it comes to changing biodiversity. The authors ask who decides where species can move and live and when invasive becomes native. Similarly, emotions have a big role in human-nature relations. The book shows why we grieve the loss of some species and hate some other species, and how our emotions change over time. The writers also aim to show how environmental policies, or the practice of governing species, are affected by societal discussion, emotions, scientific research, and topical concepts as well as how these policies shape biodiversity and our perceptions of different species. The authors provide fresh insights into human-nature relations and explain why we need multidisciplinary approaches in order to fully understand their complexity.
