Aquatic Food Production: • Food is harvested from high tropic levels

(large top consumers…example 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)

Biodiversity Soil Water Air Human Health

Loss of grasslands forests and wetland for cultivation

Loss of genetic diversity (wild crops replaced with monocrops)

Erosion Loss of fertility Salinization Desertification Increase soil pH

Waste water produced Aquifer 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 baby

Pesticides Bacterial 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 waste

Environmental impact: loss biodiversity

Outputs: Air pollution , water pollution, wheat/corn, lots of income ($$)

See “slash and burn” and “shifting cultivation”

Inputs: lots of human labor, water, sunlight

Characteristics: grow only enough to eat/ low tech

Socio- Cultural: mostly LEDC, poor Environmental impact: maintains

biodiversity, reduces pollution Outputs: Usually mixed crops; corn,

beans and squash (all in same field)

Inputs: Labor, Cattle feed/ grazing grass Characteristics: large herds of cattle,

used as only food source “Nomadic Herding”

Socio- Cultural: Cattle THE source of life (even used as currency)

Environmental impact: overgrazing, nomadic behavior

Outputs: meat, milk

Inputs: antibiotics, fish food, cages, labor

Characteristics: fish raised in large quantity

Socio- Cultural: MEDC, employs large number of workers

Environmental impact: growth of algae, water pollution

Outputs: 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 biodiversity Outputs: 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 Organisms• Change genetic make up of living things to

make them look, feel, and taste different Pesticides- used to kill pest organisms Herbicides- used to kill weeds Fertilizers- used to grow larger crops Irrigation- used to bring in more water Antibiotics/ 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 world
