  • VS

  • Aquatic Food Production: Food is harvested from high tropic levels (large top consumersexample salmon.Photosynthesis is less efficient by producers due to light reflection of water

  • Terrestrial Food Production:Most food harvested from low tropic levels (producers / herbivores)

  • BiodiversitySoilWater AirHuman Health

  • Loss of grasslands forests and wetland for cultivationLoss of genetic diversity (wild crops replaced with monocrops)

  • ErosionLoss of fertilitySalinizationDesertificationIncrease soil pH

  • Waste water producedAquifer depletion from increased irrigation

  • Large fossil fuel use in farming equipment causes release of greenhouse gases (CO2, N2O, and CH4)Pesticide sprays

  • Nitrates in Drinking water Blue babyPesticidesBacterial contamination of meat (E. coli)

  • Inputs: Fertilizers, pesticides, fossil fuels, labor, sunlight, water equipment Characteristics: Heavy use of fossil fuels, lots of farming technology, monocrops (only one crop)Socio- Cultural: Fast production, large amounts, lots of wasteEnvironmental impact: loss biodiversityOutputs: Air pollution , water pollution, wheat/corn, lots of income ($$)

  • See slash and burn and shifting cultivation

  • Inputs: lots of human labor, water, sunlightCharacteristics: grow only enough to eat/ low techSocio- Cultural: mostly LEDC, poorEnvironmental impact: maintains biodiversity, reduces pollutionOutputs: Usually mixed crops; corn, beans and squash (all in same field)

  • Inputs: Labor, Cattle feed/ grazing grassCharacteristics: large herds of cattle, used as only food source Nomadic HerdingSocio- Cultural: Cattle THE source of life (even used as currency) Environmental impact: overgrazing, nomadic behaviorOutputs: meat, milk

  • Inputs: antibiotics, fish food, cages, laborCharacteristics: fish raised in large quantitySocio- Cultural: MEDC, employs large number of workersEnvironmental impact: growth of algae, water pollutionOutputs: salmon, water pollution

  • Inputs: labor, seed Characteristics: fish and rice grown together in same, self sustaining ecosystem (fed by natural food chain)Socio- Cultural: LEDC countries, Environmental impact: reduces waste maintains biodiversityOutputs: rice, fish, income

  • Slash and burn- Farmers will slash or cut down a forest and burn the area in order to create a field for farming. Shifting Cultivation- Farmers utilize soil and forests for harvesting wood and crops until soil loses fertility, then they will move to a new area.

  • GMO- Genetically Modified OrganismsChange genetic make up of living things to make them look, feel, and taste differentPesticides- used to kill pest organismsHerbicides- used to kill weedsFertilizers- used to grow larger cropsIrrigation- used to bring in more waterAntibiotics/ Growth Hormones- used to grow healthier and larger animals

  • Food production in our country has a direct impact on the lifestyle and income of others around the worldhttp://vimeo.com/8812686
