5.1 & 5.2 The Tragedy of the Commons / Clearcutting
5.3-5.6 Agriculture / Irrigation / Pest Control
5.7-5.8 Meat Production / Overfishing
5.9 Mining
5.10 Urbanization
100
Cutting and burning vegetation to return nutrients to the soil and plant crops there.
Slash & Burn
100
The farming of one specific crop
Monoculture/Monocropping
100
Agricultural meat, dairy, or egg facilities where animals are kept and raised in confinement
CAFO
100
A rock that contains metal or an economically useful mineral
Ore
100
This refers to a metropolitan area spreading out into surrounding rural areas.
urban sprawl
200
The process where components of soil are lost due to running water, wind, or both
Soil Erosion
200
This efficient irrigation method delivers water directly to plant roots through tubes or pipes.
drip irrigation
200
Animals are allowed to graze on grass outside and grow at a natural rate without hormones
Free Range Grazing
200
Layer of soil and rock overlying a mineral deposit. Surface mining removes this layer
Overburden
200
This is a major consequence of urban sprawl, involving the loss of trees and native vegetation.
deforestation
300
"New Year New TRIPLE"
What are the three major benefits that Forest provides?
Filter of Air Pollutants
Removal & Storage of CO2 from atmosphere
Habitat for Organisms
300
This irrigation system uses gravity to channel water through small trenches between crop rows.
furrow irrigation
300
Large open storage pits for animal waste
Manure Lagoons
300
The removal of large portions of soil and rock, called overburden, in order to access the ore underneath. An example is strip mining, which removes the vegetation from an area, making the area more susceptible to erosion.
Surface Mining
300
This type of land use includes roads, sidewalks, and parking lots that do not absorb water.
impervious surface (or impermeable surface)
400
The tendency of a shared, limited resource to become depleted because people act out of self-interest for short-term gain is generally referred to as
the Tragedy of the commons
400
The process where a pollutant increases in concentration as it goes up trophic levels
Ex. DDT
Biomagnification
400
Dragging a large net across the floor
Bottom Trawling
400
water is normally rich in heavy metals that drain from either tailings or underground mines
Acid Mine Drainage
400
Describe the cause of saltwater intrusion
Excessive groundwater withdrawal near coast lowering water table pressure, allowing saltwater to seep into groundwater
500
What are Externalities?
negative costs associated with a human action, that are not accounted for in the price (unintended side-effects)
500
Describe how soil salinization occurs
Salinization is the process of salt building up in a soil over time
Groundwater used for irrigation naturally has small amounts of salt
Water evaporates, and salt is left behind in soil. Over time, it can reach toxic levels, dehydrating plant roots & preventing growth
500
What is a solution to the overgrazing of free rage grazing animals?
Rotational Grazing
500
This term describes the restoration of mined land to a natural or economically usable state.
land reclamation
500
What is one solution to prevent urban sprawl?
urban growth boundaries, public transport& walkable city design, mixed land use
