Document Summary
The world cancer research fund recommends we eat no more than 500g of cooked red meat per week. Equivalent to about 750g raw per week. Equivalent to around 39 kg per year. As income rise, more meat is consumed, meaning more grain is needed and more fertilizer used. Livestock sector- single largest user of land. Of all arable land- feed production. Deforestation (for expansion of grazing land and cropping land for livestock) key issue in latin american. Water use (>8% of global human water supply) Livestock production is largely an expression of poverty, particularly in developing countries. Ghg emissions climate variable & change. Modern agriculture currently contributes around 14% of greenhouse gas emissions. Of these, animals are responsible for 31%, and fertilisers for 38% Approximately half of all cereals grown globally are fed to animals. Global agriculture consumes 70% of all freshwaters extracted for human use. Intensive livestock production is probably the largest sector- specific source of water pollution.
