Urbanization and Ecological Footprints
Define urbanization.
Urbanization: removing of vegetation to convert natural landscape to city.
Define integrated pest management.
Define sustainability.
Sustainability: consuming a resource in a way that does not deplete it for future generations.
What is sustainable forestry?
Harvesting lumber in a way that is minimizes damage to ecosystems.
What is aquaculture?
Raising fish or other aquatic species in enclosures under water.
Define ecological footprint
Ecological footprint: measure of how much a person/group consumes in terms of land
What was the green revolution?
The green revolution was a shift from small scale farms to large, industrial farms
True or false: As the human population grows, resource depletion grows.
True
What is the no till method?
Method of sustainable agriculture that involves leaving leftover crop remains in soil instead of tilling them under.
What are some consequences of urban runoff?
pollution, decreased groundwater recharge.
What are some factors that can increase one's ecological footprint?
Traveling (gas), meat consumption, fossil fuel usage, etc/
GMO's, pesticides, advanced irrigation, and synthetic fertilizers.
What is maximum sustainable yield?
The maximum sustainable yield of a resource is how much can be used/harvested without depleting it for future use.
What is selective cutting?
Only cutting the biggest/oldest trees in an area to maintain biodiversity.
What are the pros of aquaculture?
reduces the risk of fishery collapse, requires only a small amount of space
How does urbanization impact groundwater?
What are some downsides of IPM?
What are some resources that are commonly harvest in unsustainable ways?
Why are prescribed burns ultimately helpful?
Prescribed burns remove trapped biomass that could potentially cause a bigger fire in the future.
What are the cons of aquaculture?
high density = high disease risk and high waste output
What is a solution to urban sprawl?
Urban growth boundaries: zoning laws to prevent development beyond a certain boundary
What is biocontrol?
Introducing a natural predator to eliminate pests
How does increased biodiversity signify sustainability?
high biodiversity = less harmful disruptions to ecosystem = more resources.
What is contour plowing?
plowing parallel to natural slopes to prevent water runoff and soil erosion.
How can pervious pavement help decrease urban runoff?
Allows for infiltration, decreases the amount of water that flows into storm drains or surface water
