This book argues that one of the key roles of education, whether at home or school, is to prepare young people for a future that will be very different from today. It is a practical book which outlines the key elements of a more green and sustainable future and how these can be explored with young people. In particular it sets out ways of thinking more critically and creatively about the future and sets out eight visual scenarios which illustrate different aspects of a more sustainable future. It emphasises the need for engaged optimism with a range of practical activities for young people involving both envisioning and practical action for change.
