The declines in Pacific bluefin tuna populations during this time could potentially be linked to the global popularity of sushi. As sushi became more popular worldwide, there was likely an increase in demand for Pacific bluefin tuna, leading to overfishing and a decline in their populations.
Two ways that humans around the world could help Pacific bluefin tuna populations increase include implementing stricter fishing regulations and enforcement to prevent overfishing, and promoting sustainable fishing practices that allow the population to recover. Additionally, consumers can also help by choosing sustainably sourced tuna and avoiding purchasing products that contribute to the decline of Pacific bluefin tuna populations.
