Last month in Cambridge, volunteers from the community group Fin Free Cambridge delivered a petition with over three and a half thousand signatures to the Guildhall. The group, and all the signatories, are hoping to make Cambridge the first UK city to ban the use of shark fins. Currently four businesses in Cambridge use shark fins and the UK is ranked 19th in the world for shark fin exports. Shark finning is a cruel and wasteful activity, with around 73 million sharks being killed each year for their fins alone. The number of threatened shark species in the world has grown to more than 180 from a total of just 15 in 1996.
