A vibrant team of eco-warriors and communicators birthed this book. I cannot thank enough the experts who provided valuable input, new ideas and salient facts. Some of them feature prominently in this book; some of them are mentioned in passing. Their knowledge and experience is broad and deep, and I have simplified and summarised it in ways they may not appreciate. All omissions and errors are mine so, if you know better, sympathise with them and save your ire for me.
