Bluefin tuna comeback shows nature can recover, says WWF

WWF says bluefin tuna have returned in large numbers off the British coast after nearly disappearing from UK waters, highlighting how conservation can work. The charity’s Living Planet Report 2026 links the tuna recovery to international actions such as reducing catch quotas, setting size limits, and protecting spawning grounds, backed by consumer, chef and retailer campaigns. WWF-UK’s chief scientific adviser, Mike Barrett, told the BBC it’s “not too late.” The report also notes that monitored wildlife populations worldwide have fallen by an average of 73% since 1970, even as some regions show gains. WWF tracks nearly 36,000 populations across almost 6,000 species.
