Consumptogenic System Fuels Health Inequity
- The global consumptogenic system drives planetary health inequity through policies, institutions and commercial activities.
- Transforming that system is essential to reduce harms to human and planetary health.
Heat As A Direct Health Threat
- Climate change directly harms bodies via heat stress, raising respiratory and cardiovascular risks.
- Australia models predict heat-related mortality could increase by about 200% with 2°C warming.
Biodiversity Loss Threatens Nutrition
- Biodiversity loss and pollinator decline threaten food security and deepen undernutrition and overnutrition.
- Those worst affected will be socially and economically disadvantaged populations.
