Animal Welfare and Climate Change: Intersecting Crises

Climate change is emerging as one of the most significant threats to animal welfare globally, affecting wild animals through habitat loss and extreme weather, and farm animals through heat stress and disease, while dietary shifts toward plants reduce both emissions and animal suffering.

Key Facts

Welfare Considerations

Climate change and animal welfare are deeply interconnected. The environmental stressors of climate change — extreme heat, drought, flooding, wildfire, and ocean acidification — cause direct welfare harm to animals across every ecosystem. Wild animals facing habitat transformation have limited capacity to adapt within generations. Farm animals exposed to increasingly frequent extreme heat events suffer from heat stress that impairs wellbeing, fertility, and immune function. The dietary choice dimension of this relationship is significant: reducing animal product consumption reduces the greenhouse gas emissions driving climate change while simultaneously reducing the number of animals in welfare-compromised farming systems. The same dietary shift that addresses climate change addresses farm animal welfare — making diet change one of the highest-leverage welfare and environmental interventions available to individuals.
