One Health: Connecting Human, Animal, and Environmental Welfare

The One Health framework recognizes that human, animal, and environmental health are inseparably linked. Improving animal welfare often simultaneously improves human and ecosystem health.

Key Facts

Over 60% of known infectious diseases have animal origins, many linked to poor welfare conditions
Antibiotic resistance from livestock affects the effectiveness of human medicine directly
Deforestation for agriculture drives both biodiversity loss and zoonotic disease emergence
Wildlife disease surveillance that protects animal welfare also provides early warning for human pandemics
Programs that improve livestock welfare reduce vector-borne disease risk in farming communities

Welfare Considerations

One Health thinking transforms animal welfare from a standalone cause to a component of integrated health systems. Improving farm animal welfare by reducing disease pressure and antibiotic use directly benefits human health through reduced resistance risk. Protecting wild animal welfare through habitat conservation prevents zoonotic spillover. The welfare of animals and the welfare of humans are not competing priorities but mutually reinforcing ones.
