Sustainability is a pressing concern for people and governments around the world, but it is also an essentially contested concept that requires an understanding of the stakes, trade-offs, and complex politics at play. Sustainability: The Basics offers an accessible and interdisciplinary introduction to the concept, and discusses key questions such as:

• What are the core principles of sustainability?
• What are the key ethical considerations for questions of sustainability?
• How do we measure sustainability?
• What are the critical obstacles to achieving global sustainability?
• What happens when societies fail to observe principles of sustainability?

Fully updated in its second edition, Sustainability: The Basics now includes coverage of the Sustainable Development Goals, a global range of case studies and explores the complex social dynamics of Earth system changes that affect our critical life supports. The second edition also proposes a new, "sustainable humanism" that animates much of our work to make a better, more humane world.

As the world reels from the effects of the Covid-19 pandemic, this book is an ideal starting point for anyone who wants to know more about what we need to do to sustain civilization, humanity, and the world we live in.
