100

The measure of the area of land and water an individual, population, or activity requires to produce all the resources it consumes and to process the waste it generates.

ecological footprint

100

Consuming a resource or using a space in a way that does not deplete or degrade it for future generations.

Sustainability

100

Introducing a natural predator to control pest population.

Biocontrol

100

Crops that live year round and one harvested numerous times.

perennial crops

100

What is aquaculture

Raising fish, or other aquatic species in cages/enclosures underwater

200

What is a carbon footprint?

  • All CO2 released from an individual or groups consumption & activities

200

What is Maximum Sustainable Yield?

The maximum amount of a renewable resource that can be harvested without reducing or depleting the resource for future use

200

What is a drawback of IPM?

Can be more time consuming & costly than just crop dusting pesticides

200

Plowing parallel to natural slopes of land instead of down slopes, which prevents water runoff and soil erosion.

Contour Plowing

200

Why are prescribed burns beneficial to forests?

Uses up dead biomass (fuel), preventing larger forest fires later

300

Identify THREE factors that can INCREASE an ecological footprint


  • Affluence (wealth) increases carbon & ecological footprint (Larger houses, More travel (gas), More resources needed for material goods (cars, etc.)

  • Meat consumption - more land, more water, more energy

  • Fossil fuel usage (heating, electricity, travel, plastic)

300

What are TWO major consequences of Urban Runoff?

Decreased infiltration (groundwater recharge)

Rain washes pollutants into stormdrains & into local surface waters

300

What type of IPM can prevent pests from becoming established in the soil?

Crop Rotation

300

How does Green Manure improve soil fertility?

leftover plant matter from cover crop  left on field  breakdown and releaase nutrients into soil 

300

What are THREE benefits of Aquaculture

  • Requires only small amount of water, space, and fuel

  • Reduces risk of Fishery collapse (90% population decline in a fishery)

  • Doesn’t take up any land space (compared to beef, pork, chicken)





400

Identify THREE factors that can DECREASE an ecological footprint

  • Renewable energy use (wind, solar, hydroelectric)

  • Public transportation (less gas)

  • Plant-based diet

400

What are the FOUR Environmental Indicators of Sustainability?

Biodiversity

 Food Production

Atmospheric Temp & CO2

Human Population/ resource depletion.  

400

What are THREE benefits of IPM

Reduces death & mutations of non-target species

Reduces effects on human consumers of produce

Reduces contaminants of surface & ground water

400

Which type of plants should you plant during crop rotation that have nitrogen-fixing bacteria in their roots?

peas/beans (legumes)

400

What are the FOUR drawbacks of Aquaculture?

  • High density produces high concentration of waste (e. coli & eutrophication risks)

  • High density increases disease risk, which can be transmitted to wild populations as well

  • May introduce non-native species or GMOs to local ecosystem if captive fish escape

  • Fish are fed antibiotics which can contaminate water via their waste






500

If everyone lived like an average U.S. resident, it would take approximately _____________ Earths to sustain global consumption 

 5.0 to 5.1

500

What are FOUR solutions to urban runoff?

Permeable Pavement

Rain Garden

Public Transit

Building Up, not out

500

Describe Intercropping

Push-pull system

  • “Push” plants emit volatile chemicals that naturally repel pests away from crop

  • “Pull” plants emit chemicals that attract moths to lay eggs in them, instead of crop
500

How does Limestone neutralizing the soil improve soil fertility?

  • Acidic soil has high H+ ion concentration, which displaces + charge nutrients from soil (leeching them out)

500

Identify FIVE sustainable forestry practices

  • Selective cutting or strip cutting

  • Using human & pack animal labor to minimize soil compaction from machinery

  • Replanting same species being logged

  • Using recycled wood, or simply reusing without recycling (furniture, decoration)

  • Selectively removing diseased trees to prevent spread of infection through entire forest
