On Monday, she was joined lawmakers at the California state Capitol 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 that have had their fins sliced off die when tossed back into the ocean.
Derek called shark-finning "a global environmental crisis." She says sharks have been around nearly 400 million years but says "many stocks may be wiped out."
U.S. law restricts the practice but cannot stop it in international waters. The California market for shark-fin soup is the largest outside Asia.
The bill, AB376, was passed previously by the Assembly and is one of hundreds awaiting final action.
