Unit 5: Agriculture Review

Consists of raising and growing plants and animals for human use

• domestication
• shifting agriculture
• intensive farming
• commercial farming
• overgrazing

Mid-20th century with the advances in plant biology; the development of higher-yielding, disease-resistant, faster-growing varieties of grains

• Green Revolution
• Columbian Exchange
• Second Agricultural Revolution
• First Agricultural Revolution
• Industrial Revolution

The transition of land from fertile to desert

• desertification
• aquifer depletion
• deforestation
• wetland destruction
• soil degredation

Providing the best outcomes for human and natural environments both in the present and for the future. Relates to development that meets today's needs without compromising the ability of future generations to meet their own needs.

• sustainability
• carrying capacity
• organic farming
• desertification
• wetland destruction

The reduction in available water for consumption due to pumps; ground water depletion

• aquifer depletion
• deforestation
• wetland destruction
• soil degredation
• desertification

Process by which humans use engineering techniques to change the DNA of a seed

• genetically modified organisms (GMOs)
• value added specialty crops
• economies of scale
• biodiversity
• biotechnology

The decline in soil quality as a result of improper use; one of the main arguments against chemical farming is that the pesticides, herbicides, and fertilizers damage the soil quality, which can lead to desertification or loss of top soil

• soil degredation
• deforestation
• wetland destruction
• aquifer depletion
• desertification

Goods that have some other product in them or item attached to them to make them unique and able to sell at higher price

• value added specialty crops
• genetically modified organisms (GMOs)
• economies of scale
• subsistence goods
• commercial goods

Farmers focus on raising one specific crop to sell for profit

• commercial farming
• shifting agriculture
• intensive farming
• extensive farming
• pastoral nomadism

An integrated system common in developed regions, such as the Midwestern United States, northern Europe, and Canada; on these farms, the majority of the crops raised are fed directly to livestock

• mixed crop/livestock
• Mediterranean agriculture
• truck farming
• plantation farming
• organic farming
