On his trip to Asia, President Trump ate shark fin soup in Vietnam. While this meal is considered a status symbol, delicacy and a sign of wealth in Asian culture (it can sell for over $100 a serving in restaurants), the continued consumption of shark fin soup has a devastating effect on shark populations around the world.
Shark fin soup is believed by some to have medicinal healing properties and its proponents view its consumption as a cultural right. Sharks rely heavily on international and regional treaties for protections and management measures, and in some countries domestic regulations have been adopted.
