Foxes, buzzards, crows, badgers, weasels, seals, kites - Britain and Ireland's predators are impressive and diverse and they capture our collective imagination. But many consider them to our competition, even our enemies. The problem is that predators eat what we farm or use for sport. From foxes and ravens attacking new-born lambs to weasels eating game-bird chicks, predators compete with us, putting them directly into the firing line. Farming, fishing, sport and leisure industries want to see numbers of predators reduced, and conservation organisations also worry that predators are threatening some endangered species. Other people, though, will go to great lengths to protect them from any harm. This clashing of worlds can be intense. So, what do we do? One of the greatest challenges facing conservation today is how, when and where to control predators. It is a highly charged debate. Mary Colwell travels across the UK and Ireland to encounter the predators face to face. She watches their lives in the wild and discovers how they fit into the landscape. She talks to the scientists studying them and the wildlife lovers who want to protect them. She also meets the people who want to control them to protect their livelihoods or sporting interests. In this even-handed exploration of the issues, Mary provides a thoughtful and reasoned analysis of the debates surrounding our bittersweet relationship with predators.
