We all need food to survive but many of us give relatively little thought to where our food actually comes from. The world's population is expanding, placing even greater pressure on the land, which leads to problems such as erosion, pollution and loss of important habitats and wildlife. Farming methods must change to deal with these problems. This book considers examples from across the world that show there are alternative, sustainable ways to provide food for everyone, without further harming the environment. By exploring the idea of sustainable food and farming, this book shows how readers can also play an active part in ensuring a more sustainable future. 'Databank' boxes give key facts, 'Opinion' panels highlight quotes from well-known speakers on the subject. There are also weblinks with useful website addresses which link to sites with more information about a particular topic. - from Amzon
