How the global demand for seafood is leading Chinese factories to pollute an African nation

Gunjur, a town of some fifteen thousand people, sits on the Atlantic coastline of southern Gambia, the smallest country on the African continent. During the day, its white-sand beaches are full of activity. Fishermen steer long, vibrantly painted wooden canoes, known as pirogues, toward the shore, where they transfer their still-fluttering catch to women waiting at the water’s edge. The fish are hauled off to nearby open-air markets in rusty metal wheelbarrows or in baskets balanced on heads. Small boys play soccer as tourists watch from lounge chairs. At nightfall, work ends and the beach is dotted with bonfires. There is drumming and kora lessons; men with oiled chests grapple in traditional wrestling matches.
