Human activities are pushing the ecological boundaries of Earth. Rapid changes in climate and the environment create a complex, intertwined tangle of wicked problems. Sustainability science, whose focus is the interactions between humankind and nature, is the academic world’s response to the call to solve these problems. The Avenues to Sustainability – Key Lessons from Sustainability Science is a comprehensive introduction to the concepts and theories of sustainability science, as well as to the ways in which the sustainability transformation of society could be accomplished. It also discusses how daily life, learning, cultural heritage, and art can foster a sustainable way of life. A timely guide to sustainability science and theory both to policymakers and ordinary citizens, The Avenues to Sustainability can also be used as a university textbook. In addition to research-based knowledge, the book includes contributions from actors in the public sector, businesses, NGOs, and others in Finland.
