Some good news for sharks: The US has banned the odious shark-fin trade, a move conservationists hope will help protect millions of sharks butchered every year. The Shark Fin Sales Elimination Act, introduced in 2021, is now law, making it illegal to possess, buy, sell, or transport shark fins or any product containing shark fins. Violators (who are truly vile) face up to $100,000 in fines.
