Evidence categories with use limits.
Each source group supports a different kind of claim. Global statistics are useful for direction, but local design
still requires local measurements, community consent, code review, and ecological observation.
Source category
Land use and food-system emissions
Supports: Agriculture occupies a very large share of habitable land, livestock dominates agricultural land use, and food systems are a major greenhouse-gas source.
Caveat: Global averages do not automatically describe every local farm. Use local land, diet, and production data where available.

Biodiversity and land/sea-use change
Supports: Land/sea-use change, exploitation, climate, pollution, and invasive species are major biodiversity drivers; many species face extinction risk.
Caveat: Biodiversity loss is multi-causal. Do not reduce all extinction risk to factory farming alone.

Livestock environmental pressure
Supports: Livestock systems affect greenhouse gases, land, water, nutrient pollution, manure management, and biodiversity.
Caveat: Livestock systems vary widely. Extensive, integrated, pastoral, and high-welfare systems should not be treated as identical to dense confinement systems.

Antimicrobial resistance
Supports: Routine antimicrobial use in healthy food animals can select for resistant bacteria; WHO recommends reducing growth-promotion and routine preventive use.
Caveat: Treatment of sick animals remains important. The evidence supports better husbandry and targeted veterinary use, not neglect.

Zoonotic and One Health risk
Supports: Zoonotic risk is shaped by land-use change, wildlife exploitation, animal protein demand, agricultural intensification, food-supply changes, travel, and climate change.
Caveat: No single driver explains all pandemic risk. Use One Health framing across human, animal, and environmental systems.

Tax, nonprofit, and land trust boundaries
Supports: Donations, restricted gifts, land gifts, and conservation easements require documentation, qualified nonprofit review, and often legal/tax/appraisal support.
Caveat: This website is educational only. It does not issue receipts, verify deductibility, provide legal advice, or appraise property.
