This book is divided into three chapters. Chapter one is definitional. I define what sustainability means, including different perspectives that may help you to understand and apply the concept. The second chapter is normative. Norms are about our values and value system. Essentially, norms related to how people live and what they value. The third chapter is instrumental. It’s a way of applying sustainability in your life. In this chapter I will work through some things to consider when making choices about essential items such as fashion, food, and everyday living.
