Sharks have a far more to fear from us than we do from them. The staggering statistic of 11,000 sharks dying every hour due to industrial fishing opens the discussion about their shocking mortality rates. Challenges in data collection and underreporting complicate our understanding of these figures. Advanced techniques like machine learning are helping to improve estimates. Meanwhile, conservation efforts, though well-intentioned, can sometimes backfire, exacerbating the decline in shark populations.
