First Published in 2000. The timing of this book is auspicious in that we can look backwards at the twentieth century as the period of maximum environmental impact by humans in their history, while looking forward to a new era of potential improvement by drawing on and learning from this experience. This book's purpose, therefore, is to consider how to address education for children to become informed and concerned adults who will be able to understand critically the implications of these choices and act wisely in the wider interests of society and the planet as a whole.
