Shark Stories

Have Shark Populations Boomed?


Listen Later

In this episode, we dive into the ongoing debate about whether shark populations are truly booming or if this claim is based on misconceptions. With growing concerns from fishermen, particularly in the U.S. and viral discussions on social media, we explore whether sharks are increasing in numbers or simply recovering to historical baseline levels. Joining the conversation is marine ecologist and investigative journalist Spencer Roberts, who provides insights into the factors fueling the "shark overpopulation" hysteria. Tune in for an evidence-based look at shark conservation, media narratives, and what’s really happening in our oceans.
