Under a Metal Sky

The discovery of minerals beneath our feet has transformed our species. Ochre first prompted humans to express themselves in art; tin and copper helped instigate the Bronze Age and later the Industrial Revolution; silver kick-started the engines of global trade. Each of these substances generated a leap forward in technology, each one opened the imagination a little further - and each one brought with it a cache of unexpected dangers. 'Under A Metal Sky' begins and ends in Philip Marsden's homeland of Cornwall, one of the world's great geological hotspots. Rich with revelations, this book traces the dazzling achievements and dark consequences of our ability to extract what we want from the earth, and presents a fascinating new perspective on European history and on our troubled relationship with the natural world.
