Marine environments have long been places of exploration, subsistence, transport and trade, but it is only recently that marine tourism has extended beyond coastal resorts and beaches. Demand for marine wildlife experiences has grown considerably in recent decades but a corresponding increase in the conservation of these environments as well as adequate legislative and management responses aimed at sustainability has not yet followed. This book demonstrates that through scientific approaches to understanding and managing tourist interactions with marine wildlife, sustainable marine tourism can be achieved. Drawing from disciplines such as marine and conservation biology and behavioural ecology, the effects of human disturbance on marine wildlife as well as management approaches to moderate these impacts are explored. Social science perspectives are also used to understand consumer demand and the ethical and legislative problems that this demand creates. This comprehensive volume provides valuable insights for both researchers and practitioners in marine conservation and tourism.
