The document discusses shark finning, which involves removing a shark's fins and discarding the rest of its body at sea. It notes that tens of millions of sharks are killed annually for their fins to supply the lucrative shark fin trade, primarily to meet demand for shark fin soup. This unsustainable practice has led to sharp declines in many shark populations worldwide and threatens marine ecosystem stability. While some regulations have been implemented, more protections are still needed to curb overfishing and finning and allow shark populations to recover.
