- Pollination: About 75% of the world’s leading food crops benefit from animal pollination; declines in pollinators reduce yields and crop diversity (FAO).
- Economic value: Animal pollination contributes hundreds of billions of dollars to global crop production annually (estimates commonly cited in the literature).
- Clean water: Wetlands, forests and riparian zones naturally filter pollutants; loss of these systems increases water treatment costs and contamination—unsafe water still causes roughly 800,000+ deaths per year (WHO).
- Climate regulation: Forests and oceans store vast amounts of carbon; land-use change and deforestation account for roughly 10% or more of global greenhouse gas emissions (IPCC/Global Carbon Project).
- Consequence for food and health: The IPBES global assessment warns biodiversity and ecosystem decline undermines food security, nutrition and disease regulation, raising risks of hunger and illness as ecosystem services fail.
