Agriculture
What is monocrpping ?
Growing only one crop over a large area.
What is clear cutting ?
Cutting down all trees in an area at once.
What is subsurface mining ?
Extracting minerals from deep underground.
What is overfishing ?
Removing fish faster than that popullation can reproduce.
What is the largest use of freshwater globally?
Agriculture/irrigation.
Name a negative environmental effect of industrial agriculture ?
Soil degradation and water pollution.
Why is clear cutting harmfull ?
Increases erosion along with habitat loss.
Name one impact of urban sprawl.
Habitat fragmentation and more pollution.
What is aquaculture ?
Farming fish or aquatic organisms.
What is the difference between point and nonpoint pollution?
Point: Specific source; Nonpoint: Diffuse source.
What is integrated pest management (IPM) ?
Using multiple methods to control pest with minimal environmental harm. Cultural, mechanical, biological, and chemical, to control pests in a sustainable way
Define sustainable forestry.
Managing forests to meet current needs without harming future generations.
What is reclamation in mining ?
Restoring land after mining activit.
Give one pro or one con of aquaculture
Pro: Efficient protein; Con: Pollution, disease
What’s one method to conserve water in agriculture?
Drip irrigation.
What does organic agriculture aviod using ?
Synthetic fertilizers and pesticides.
what U.S law governs forest land use ?
Why is urbanization a problem for water systems ?
Increases runoff, pollution and reduces infilltration.
What’s a marine protected area?
An ocean space where fishing or drilling is restricted or banned.
What is desalination ?
Removing salt from water to make freshwater.
What is the “Tragedy of the Commons,” and how does it apply to overgrazing in agriculture?
What is the overuse of shared resources due to individual self-interest, leading to resource depletion, such as overgrazing shared pastures?
Compare the ecological impacts of clear-cutting vs. selective cutting.
What is that clear-cutting removes all trees, causing severe habitat loss and erosion, while selective cutting removes specific trees, minimizing ecosystem disruption?
Explain how urban heat islands form and their relationship to land use.
What is the trapping of heat in urban areas due to dark surfaces (asphalt, buildings) and reduced vegetation, which alters local climate and energy use?
Describe two regulations or techniques that help make fishing more sustainable.
What are catch limits, size restrictions, seasonal closures, marine protected areas, or gear modifications like turtle excluder devices?
Explain how groundwater overdraft can lead to land subsidence and reduced water availability.
What is that removing groundwater faster than it’s replenished can cause the land to sink and lower the water table, reducing long-term water supply?
