Within two days, authorities launched an emergency vaccination programme for more than 5,000 of the species, an intervention unprecedented in scale and urgency. The effort reflects a broader truth: in an age of accelerating ecological disruption, the fate of a beloved creature and the fate of a nation's economy can be inseparable.
