Actress Bo Derek joined lawmakers at the California state Capitol on Monday promoting a bill that would ban selling, trading or possessing shark fins, which are used in a soup that is considered a delicacy in some Asian cultures.

"Sharks have been around for nearly 400 million years, and yet many stocks may be wiped out in a single human generation due to the increasing demand for shark fins," Derek, who is a US secretary of state special envoy opposing wildlife trafficking, told the Senate Appropriations Committee.
