Arctic and Antarctic wildlife tourism exposes polar animals to human disturbance that can affect breeding success and individual welfare.
Polar wildlife disturbed by tourism shows measurable stress responses including elevated corticosterone. Breeding animals disturbed during critical periods may abandon nests or fail to recognize returning mates. The cumulative effect of thousands of tourist visits per season at popular sites may be ecologically significant. Climate stress is already reducing population resilience, meaning that tourism-added stress may have greater welfare impact than in more stable conditions.
