Why are japenese sea lions extinct?

Japanese sea lions became extinct primarily due to overfishing and habitat degradation, which reduced their food sources. Additionally, hunting and culling by fishermen, who viewed them as competitors for fish, significantly contributed to their decline. By the mid-20th century, these pressures had led to their disappearance, with the last confirmed sighting occurring in the 1950s. Conservation efforts were too late to save the species, highlighting the impact of human activities on marine life.
