While politicians, entrepreneurs, and even school children could tell you that sustainability is an important and nearly universal value, many of them, and many of us, may struggle to define the term, let alone trace its history. What is sustainability? Is it always about the environment? What science do we need to fully grasp what it requires? What does sustainability mean for business? How can governments plan for a sustainable future? 

This short, accessible book written in the signature question-and-answer format of the What Everyone Needs to Know series tackles these and numerous other questions. Sustainability is a porous topic, which has been adapted and reshaped for developing ecological models, improving corporate responsibility, setting environmental and land-use policies, organizing educational curricula, and reimagining the goals of governance and democracy. Where other treatments of this topic tend to focus on just one application of sustainability, this primer encompasses everything from global development and welfare to social justice and climate change. With chapters that discuss sustainability in the contexts of profitable businesses, environmental risks, scientific research, and the day-to-day business of local government, it gives listeners a deep understanding of one of the most essential concepts of our time.
