Tigers, tuna and otters show nature can still recover

The latest Living Planet report, produced by WWF in collaboration with the Zoological Society of London, reveals that wildlife populations worldwide have plummeted by an average of 73% since 1970. However, amidst this grim statistic, there are glimmers of hope that nature can bounce back when given the chance. This story explores several species that have shown signs of recovery, highlighting the importance of proper protections and conservation measures.

Among the species that have made notable comebacks are tigers, sea otters, southern African elephants, green turtles, and Atlantic and Pacific bluefin tuna. For instance, wild tiger numbers have increased by around 70% since 2010, thanks to dedicated conservation efforts. Similarly, European bison, once extinct in the wild, have been reintroduced to ten countries over the past five decades.

The Atlantic bluefin tuna, once abundant off the British coast but now endangered, is a prime example of a species that has rebounded with tighter management from governments and the fishing industry. Populations have recovered enough for the bluefin tuna to be spotted and caught once again in British waters. Otters, once pushed to the brink of extinction in the UK, have made a remarkable resurgence across much of the country, with beavers and white-tailed eagles also successfully reintroduced after disappearing altogether.

However, these success stories are overshadowed by the fact that wildlife is still declining globally. The report attributes this decline to several major drivers, including habitat destruction, agriculture, and climate change. Agriculture remains the largest cause of habitat loss, while climate change exacerbates the challenges already faced by vulnerable ecosystems.

The consequences of these losses extend far beyond the wildlife themselves. Healthy ecosystems provide essential services such as food production, clean water, fresh air, and medicines, and play a crucial role in regulating the climate. In fact, WWF estimates that nature underpins around half of the global economy, valued at approximately $58 trillion in 2023.

While these recoveries provide grounds for hope, the report warns that some ecosystems may reach "tipping points" beyond which recovery becomes increasingly difficult, or even impossible. Warm-water coral reefs, for example, are considered especially vulnerable to tipping points.

The message from these success stories is clear: recovery depends on sustained action rather than mere hope. The downward trend is not irreversible, but it is a sobering reminder of the urgent need for continued conservation efforts. The lessons learned from these species that have rebounded serve as a reminder that change can accelerate once there is enough momentum behind a positive shift.
