This book could not have been possible without generous help from many colleagues, friends and organisations. First of all, I would like to thank Dr Adam Abukari. I owe an enormous debt of gratitude for his generosity, dedication and intelligence which contributed greatly to this book. I am also immensely grateful to my fellow researchers and colleagues including Dr Stuart MacLennan, Dr Donato Vozza, Dr Reinhard Kreissl, Dr Fanou Rasmouki, Dr David Wright, Dr Matthew Hall, Dr Franz Reger, Stephanie Öner, Peeter Paisuots, Dr Daniel Frendo, Daniel MacGinty, Cristina Farinha, Berta Santos, Rui Felix, Ana Djakovic, Engin Erken, Nilimesh Baruah, Dr Hieke Luecke, Prof Brigitte Unger, Prof Nicholas Ryder, Dr Alison Lui, Sam Bourton, Dr Lorenzo Pasculli, Dr Stuart MacLennan and Dr Costantino Grasso. It has been a great pleasure to work with them all, who are genuinely interested in and happy to render a constructive critique for the pressing global issues which this book aims to tackle. Thank you for being there through the extraordinary and hard times which COVID-19 has imposed on us. Finally, I want to thank my wife, Jo, and my children for tolerating my anti-social working hours and disappearances in the process of writing yet another book.
