The video discusses the threat of extinction faced by many fish species due to overfishing, focusing on the Atlantic bluefin tuna, whose population has decreased by 70% in 40 years. Historically, bluefin tuna was used as pet food, but its popularity grew with the sushi market, leading to overfishing. Conservation laws now limit the number and size of tuna caught, aiming to allow young fish to reproduce. However, not all countries adhere to these laws, posing challenges to conservation efforts.
