Shark and ray populations have dropped by over 50% since 1970, threatening ocean ecosystems.

Shark and ray populations have fallen by over 50% since 1970, with overfishing, pollution, and habitat loss as key factors. The study, tracking 1,199 species, shows that large species' decline could lead to a loss of up to 22% of their ecological functions. Researchers highlight the importance of reducing fishing pressure and improving governance to protect these crucial ocean predators.
