Industrial Agricultural:

The Business of Food


Industrial Agricultural: Key Elements


Economies of Scale

Synthetic Inputs


Industrial Agriculture Practices

Large Scale Farming


  • Food travels long distances to reach consumer

  • Large amounts of fossil fuels are required to operate farm machinery and to transport food

  • Farms owned by corporations. Fewer small family farms




  • Loss of plant and animal diversity, ecosystems.

  • Disease and crop failure. If one plant gets sick in a monoculture, then all of the other plants are also susceptible to the disease.

  • Increased dependence on pesticides and herbicides.

  • Depletion of soil nutrients and biological activity.


Heavy Inputs


  • Soil, water, and air pollution

  • Depletion of ground and surface water supplies

  • Soil erosion and depletion

  • Elimination of beneficial microorganisms in soil

  • Insects and bacteria develop resistance to pesticides


Use of hormones and antibiotics


  • Soil, air, and water pollution from concentrated animal waste and dead animals

  • Harmful bacteria, resistant to antibiotics, spread disease quickly, and possibly affect humans

  • Mistreatment of animals.


CAFOs (Concentrated Animal Feeding Operations)


  • Huge amounts of animal waste, stored in areas called lagoons

  • Lagoon spills and overflows contaminate soils and groundwater, and destroy aquatic ecosystems

  • Cattle waste produces large amount of the greenhouse gas, methane, a big contributor to climate change.

  • Quick spread of disease between many animals confined to a small area

  • Animals are fed diets their bodies cannot digest

  • Discomfort, stress, injuries, and lack of exercise for animals

  • Animals are crowded in pens or sheds where movement is restricted and daylight is limited


Genetically Modified (GM) Crops


  • Potential risks posed to humans and wildlife

  • Genetically modified plants could breed with surrounding wildlife, infecting non-GM crops with GM material

  • Food grown for durability, not taste. Loss of quality

  • Loss of biodiversity (seeds)


Environmental Impacts

  • Deforestation and Species Displacement

  • Loss of Pollinators

  • Soil Erosion and Depletion

  • Loss of Genetic Diversity

  • Water depletion and pollution

  • Dependent on Fossil Fuels


Health Impacts

  • Water

    • Over two-thirds of the fresh water used by humans is used for agriculture.

  • Residue on food

  • Antibiotics, Growth Hormones, GMO

    • Antibiotic resistant strains of bacteria

    • Introduction of genetically engineered proteins to human body (rBGH)

  • Taste

Case Study:

The Green Revolution

From the 1950s to the 1970s, new agricultural technologies were introduced around the world with the goal of increasing food production. This was known as the Green Revolution.
