The need to protect our environment is broadly accepted and yet support for taking action to ensure an environmentally sustainable future appears to be dwindling. This book provides an empirical and theoretically informed discussion, with case studies from the Global North and Global South, to examine the reasons for this gulf and the ways in which society can start to reconcile demands for comfort, wealth and job security with a fragile, uncertain environmental future. This book offers a broad conceptualisation of environmentalism and provides geo-environmental analytical framework to assess what environmentalism is achieving, why, and how it could be supported to do more.
