I read this article today about the declining shark population. Hopefully they are declining at our pier!Shark Populations Plummet
The global population of sharks and rays in the high seas has fallen by more than 70% in the last 50 years, according to a study published yesterday. The researchers estimate almost three-quarters of the 31 species of pelagic sharks and rays—those that roam the open ocean—are at risk of extinction, up from one-third in 1980. Overfishing is noted as the primary cause for the decline, with the species not only targeted but often inadvertently caught as bycatch. The smooth hammerhead was the only species to see a population rise.
The researchers surveyed global data for sharks using 57 previous studies and datasets. They estimate the losses could be even deeper, as mass fishing started before population charting began in 1970. It is estimated more than 100 million sharks are killed by humans each year.
The good news? There is evidence of conservation efforts helping some localized populations rebound.
