Food Insecurity
the state of being without reliable access to sufficient quantity of affordable, nutritious food
Food Desert
place where nutritional food is inaccessible
Wasting Food
all resources used to make food wasted; waste less food, less food grown, decrease in greenhouse gases, more available land, increase in water and biodiversity

Commercial
sell for profit
Subsistence
enough to get by
Intensive
highly concentrated, needs outside inputs
Extensive
lots of land, ex. free range cattle
Monoculture
one crop specific, specialization of equipment and knowledge
Polyculture

Changes in Farming since WWII
subsistence -> agrobusiness, family -> corporations, increase in size of average farm, decrease in number of farmers, increase in mechanization, crop dusters -> safer spread of pesticide, improved refrigeration -> greater distribution distance, increase in crop yield, increase in grazing
Share of Land
shared area of land that is available land that can be used to grow stuff
Green Revolution
US state department program, bring agricultural tech to other countries, increase in food production leads to political stability, high yield varieties of cereal, chemical fertilizers and pesticides, soil treatments, controlled water supply, increase in mechanization
G.M Foods
bad, chemicals, grow faster, "non-GMO" used to persuade buyers, can't prove a negative, can't prove the safety of something, only that something isn't safe
