Roads and Wildlife Welfare: Infrastructure as a Welfare Issue

Road infrastructure causes extensive wildlife welfare harm through direct mortality, habitat fragmentation, and chronic stress from traffic noise and pollution.

Key Facts

Roads kill an estimated 1 million vertebrates per day in the US alone
Noise from roads causes chronic stress in wildlife up to 1 kilometre from major highways
Chemical pollution from road runoff affects aquatic wildlife in roadside water bodies
Light from roads disrupts wildlife chronobiology and behavior
Road networks have fragmented habitats across entire landscapes reducing wildlife welfare

Welfare Considerations

Roads are perhaps the most pervasive human infrastructure welfare impact on wildlife, causing direct mortality, habitat fragmentation, chronic noise stress, and chemical pollution across vast areas. Infrastructure design that incorporates wildlife welfare from the start — crossing structures, noise barriers, reduced light pollution, drainage management — reduces these impacts substantially. Retrofitting existing infrastructure is possible but far more expensive than designing for wildlife from the beginning.
