CLIMATE CHANGE & AGRICULTURE
‘Modern agriculture has become the art of turning oil into food.’
-B. Clark & R. York (2008:13)
“…I want to highlight the fact that among options for mitigating climate change, changing diets is something one should consider."
-Rajendra Pachauri, IPCC head

-late 19th C – global chicken population ~100,000,000
-today: chickens killed annually ~50,000,000,000
-in the US, more chickens killed in 1 day today than were killed all year in 1930

grain-fed livestock: “reverse protein factories” (Lappe)
Our ‘Ecological Hoofprint’ -protein, carbohydrates, minerals, etc. lost in
cycling feed through livestock = as livestock production expands, extra land space needed for agriculture
LIVESTOCK Prod’n =18% of anthropogenic GHG
- clearing forested land (biggest)- fertilizer (prod’n + transport)- farm vehicles- ruminant flatulence
