Animals living in high-altitude environments face unique welfare challenges from thin air, cold, and limited food that climate change is disrupting.
High-altitude wildlife has evolved specific physiological adaptations to extreme conditions — low oxygen, cold temperatures, limited food diversity — that make them vulnerable to rapid environmental change. As temperatures rise, species adapted to cold high-altitude conditions have nowhere to retreat to once they reach the summit. Welfare impacts include nutritional stress from changing vegetation patterns, increased competition as ranges compress, and greater human contact as previously remote areas become accessible. Climate action is the most important welfare intervention for high-altitude species.
