Do 11,000 sharks die every hour?

The More or Less podcast investigates the claim by marine conservation charity Sea Shepherd Global that 100 million sharks are killed annually. Host Lizzy McNeill interviews Dr. Boris Worm, a professor of marine conservation, who explains the methodology behind this estimate, highlighting the challenges of data collection and the reliance on estimations due to incomplete or unreliable government data, bycatch, and the varying sizes of sharks. Dr. Worm clarifies that the figure is an estimate with a wide margin of error, potentially ranging from 60 to 270 million, and discusses the impact of finning bans on shark mortality.
