The document discusses coastal areas and how human activities can negatively impact them. It defines coastal areas as the transitional zone between land and sea, and notes that almost half the world's population lives in these areas. Tourism, coastal developments, and overfishing are described as activities that can degrade coastal environments through pollution, habitat destruction, and unsustainable fishing practices. The document aims to explain how these human uses of coastal resources can become problematic if not properly managed.
