Analyse how the global shift of different industries affects the environment (12)
Place
Amazonia, Brazil, South America
The global shift of food production
Brazil - a middle income country whose economy never shifted to a focus on tertiary (services) and quaternary (innovation) industries
Processes
- why has global food production shifted here?
Primary and secondary (manufacturing) industries still essential to economy
The country is using what it's got to develop economically: land
The global food production system:
Agro-industrial production
Agribusinesses: TNC's involved in production and resources (seeds, fertilisers, chemicals)
Transport innovation
International market demand
Global meat consumption: 1950: 44 Mil. T > 2009: 280 Mil. T
Soy significance: global meat consumption; 1:4 protein-carb ratio for meat growth.
Power
Consequences
Environmental
Deforestation > clearance > fire
Transboundary effects of this
13 Mil. Ha of cattle grazing land was Amazon
Direct biodiversity loss
Local climate change > loss of vegetation > evapotranspiration and the water cycle
Soil erosion and land degradation
Water pollution: sedimentation, fertiliser (eutrophication), chemicals
Irrigation
Loss of carbon sink
Added emissions:
livestock alone accounts for 15% of global CO2 emissions
Methane: livestock, 15 years in atmosph., 21 times as insulating as CO2
Nitrous oxide: fertilisers and manure, 100 years, 296 times CO2 at trapping heat.
Carbon footprint
Processing > storage > transportation...
Shipping lane pollution...

Fire and PM 2.5 inhalation
Loss of biodiversity, DNA and innovation
Displacement of indigenous culture
