Rewilding and Wild Animal Welfare: Predation Ethics

Rewilding returns predators and natural processes to ecosystems. This raises profound welfare questions about predation, prey suffering, and whether wild animal suffering matters morally.

Key Facts

Wolves reintroduced to Yellowstone in 1995 transformed riparian vegetation through a trophic cascade
Natural predation typically involves pursuit, exhaustion, and a kill that may take minutes to hours
Wild animal suffering from predation, disease, parasitism, and starvation is orders of magnitude larger than farmed animal suffering by some calculations
The wild animal welfare movement is a growing academic field examining whether we have obligations to wild animals
Compassionate conservation argues that individual animal welfare must be considered alongside species and ecosystem goals
Some philosophers argue that predator reintroduction increases net suffering; others that it enables ecosystem function that supports flourishing

Welfare Considerations

Rewilding raises the most philosophically challenging welfare questions in the field. Does predation cause morally significant suffering? Do we have obligations to reduce it? The emerging consensus among welfare philosophers is nuanced: wild animal suffering is real and morally relevant, but large-scale human intervention in natural predation is neither practically feasible nor clearly beneficial given ecosystem complexity. The most tractable wild animal welfare interventions are those targeting suffering caused by human activities — habitat destruction, pollution, climate change — rather than natural processes. Rewilding, on balance, creates conditions for richer ecological communities and appears consistent with welfare when individual welfare impacts are considered alongside ecosystem outcomes.

What You Can Do

Engage with the wild animal welfare academic literature rather than dismissing the question
Support rewilding projects that include compassionate conservation principles in their monitoring frameworks
Advocate for wild animal welfare considerations in environmental impact assessments
Follow researchers like Oscar Horta, Alasdair Cochrane, and Jeff Sebo on wild animal suffering ethics
Support habitat protection and pollution reduction as the most tractable wild welfare interventions
