Rather like reading a travel guide in preparation for a journey, this first block introduces some of the language and ideas that you need to make sense of environmental change. You start by looking at two crucial global issues - loss of biodiversity and climate change - to get a sense of the influence of people on a dynamic planet. You then assess your own environmental impact in terms of your'carbon footprint' and consider how to reduce it towards a more sustainable level.Unfortunately due to copyright restrictions the DVD material refered to in this book is not available for sale as a result study of some of the activities is limited.
