How to change the world

![CDATA[This chapter will be different from the rest of this book because it is not about theory; it is about applying the knowledge that you have learnt. Specifically, it is about using your knowledge to change the world. What, you may ask, is a textbook doing telling me to change the world? Well, we hope that by reading the first 21 chapters of this book you have become more aware of two things that highlight why you should contribute to positive social change. The first is about the complex issues that surround us, and their relevance to you. You may have felt a sense of connection with or concern about some of the issues covered in this book: from the racism discussed in Chapter 9, to the environmental injustice outlined in Chapter 18, and the social inequality highlighted in Chapters 6 and 11. Hopefully the conversations we have had across these chapters have also made you look more critically at the world around you, and you may now recognise other injustices: bullying in your neighbourhood, homelessness, issues around access to food, or the health and wellbeing of your community.]]
