The food system contributes about half of human caused GHG emissions

15-20% processing, transport, packaging, retail (EU study ways 1/4 of all transport is food) 8 -10 is processing and packagin.15-18 percent from land-use change/deforestation (agriculture accounts for 70 to 90% of deforestation)11-15 % from agriculture (chem fertilizers, machinery using oil, methane from cafos)2-4 % wasteTOTAL 43 - 57 p1 ANOTHER ANGLE: 25 TO 40% OF CURRENT excess C02 in the atmosphere comes from destruction of soils and its organic matter . p 3Loss of organic matter. in 20th century cultivated soils have lost from 30 to 75% of organic matterlost from pastures and prairies up to 50%thE FOLLOWING CHANGES could cut GHG emissions in half in 50 years. p51. [using basic agro ecological practices. MY WORDING]..Organic matter could be restored to prehistoric levels within 50 years. could "offset between 24-30% of current global annual GHG emissions."2. shift to local markets to reduce transport3. reintegration of livestock and farmng (no more CAFOS)4. stoppinng land clearing and deforestation
