Actress Diane Lane and conservation advocacy group Oceana on Thursday hosted an event on Capitol Hill to encourage lawmakers to ban U.S. participation in the shark fin trade.

The trade is “something that needs to come to a graceful but quick end,” said Lane, who was sporting a silver shark necklace.

Lane is lobbying for the Shark Fin Trade Elimination Act of 2017. The bill, sponsored by Sen. Cory Booker Cory Anthony Booker3 reasons why Biden is misreading the politics of court packing Bipartisan praise pours in after Ginsburg's death DHS opens probe into allegations at Georgia ICE facility MORE (D-N.J.), outlaws buying, selling and transporting shark fins and imposes penalties on those who break the law, aiming to reduce the number of sharks killed in the fin trade.

Seventy-three million sharks are killed each year for “finning,” said Lane, using the term for the practice.

The push also comes during "Shark Week," The Discovery Channel's annual weeklong programming event intended to improve education and conservation efforts for sharks.

Lane, a longtime activist for the ocean, said she spoke with lawmakers on Wednesday, including Speaker Paul Ryan Paul Davis RyanKenosha will be a good bellwether in 2020 At indoor rally, Pence says election runs through Wisconsin Juan Williams: Breaking down the debates MORE (R-Wis.) and House Majority Leader Kevin McCarthy Kevin Owen McCarthyMcCarthy says there will be a peaceful transition if Biden wins GOP lawmakers distance themselves from Trump comments on transfer of power McCarthy claims protests in Louisville, other cities are 'planned, orchestrated events' MORE (R-Calif.), and is hosting more meetings today on ending shark finning.

“I had a marvelous day,” Lane told The Hill. “It’s wonderful to have unifying legislation that people can support, especially during Shark Week."

"Sharks are in trouble,” she continued. “I managed to have a moment with Speaker Ryan and he was kind of impressed with the number of sharks that perish every year with this being allowed to continue and how it is not sustainable."

“As you all know, facts matter, and science matters, and this isn’t playing around,” Lane added.

Lawmakers voiced optimism about moving the bill.

“It’s not just the big states like Texas, New York and California. It’s the small but powerful state of Rhode Island,” he said.

Whitehouse also joked about the bipartisan support for the bill highlighting Royce’s efforts on animal conservation.

“I know that Republicans aren’t supposed to like Democrats and for sure, members of the House are not supposed to senators, but he has been a terrific partner,” he said.

At the event, Lane also touted the economic value of shark tourism, which brings $221 million a year to Florida alone.

“I’m grateful that people are experiencing the majesty of this species firsthand,” she said.

And she said that ocean conservation should be seen as a global effort.

“It's one huge body of water that we share on the planet,” she said. “I think we need to do our part as leaders in the U.S. as far as setting the example.”
