Types of farming
Livestock and poultry: meat, dairy, and eggs; utilizes rangeland
Agriculture: growing one crop (monoculture) or many crops (polyculture)
Aquaculture: raising aquatic organisms for food
Malnutrition: a condition caused by not consuming enough necessary nutrients
Famine: a food scarcity so widespread that it causes severe malnutrition throughout large geographic areas
More population = More crops
Overnutrition: Food energy intake exceeds energy use and causes excess body fat
Similar health problems to those who are underfed
Lower life expectancy
Greater susceptibility to illness
The first agriculture recolution began as early as 9000 BC
Nomads àSettlements
Cross pollination first begun
Grew enough to support family and trade
Goals
Stop hunger
Increase crop yield
Minimize crop failure
Methods
New high grain varieties
Pesticides
Fertilizers
Better Management Practices
More technologically advanced machinery
Vision: treat agriculture as a business. Plant a large amount of a single species
Drawbacks: Too expensive, air, soil,, and water pollution to toxic chemicals
Conventional resources
Maximize output—high efficiency
Maximize space
Concentrated Animal feeding operations
Genetically modified crops
Heavy equipment
Chemicals

Sustainable farming
- Sustainable output
- Takes more space
- Pasture/rangeland feeding
- Incorporates more human and animal labor
- Minimize chemical usage
- POLYCULTURE
