All Flashcards
How can no-till farming help protect the environment?
Reduces soil erosion, improves soil health, increases water infiltration, and sequesters carbon in the soil.
How can crop rotation help protect the environment?
Maintains soil fertility, reduces pest problems, improves soil structure, and increases biodiversity.
How can integrated pest management (IPM) help protect the environment?
Reduces pesticide use, minimizes harm to non-target species, and promotes a more balanced ecosystem.
How can using organic fertilizers help protect the environment?
Reduces the risk of eutrophication, improves soil health, and promotes a more sustainable agricultural system.
How can cover cropping help protect the environment?
Reduces soil erosion, improves soil fertility, suppresses weeds, and enhances water infiltration.
How can contour plowing help protect the environment?
Reduces soil erosion by plowing along the contour lines of the land, slowing water runoff.
How can terracing help protect the environment?
Reduces soil erosion on steep slopes by creating level platforms, slowing water runoff and retaining soil.
How can windbreaks help protect the environment?
Reduces soil erosion from wind by planting trees or shrubs to block the wind and protect the soil.
How can reducing meat consumption promote sustainability?
Decreases demand for land and resources used in livestock production, reducing deforestation and greenhouse gas emissions.
How can supporting local agriculture promote sustainability?
Reduces transportation emissions, supports local economies, and promotes more sustainable farming practices.
What are the environmental consequences of slash and burn agriculture?
Deforestation, habitat loss, soil erosion, air pollution (greenhouse gases and particulate matter).
What are the environmental consequences of tilling?
Soil erosion, loss of nutrients, disrupted soil microbes, sedimentation in waterways.
What are the environmental consequences of fertilizer use?
Eutrophication, dead zones, water contamination (nitrates in groundwater).
What are the environmental consequences of pesticide use?
Harm to non-target species, pesticide resistance, human health issues (cancer, birth defects, neurological problems), biomagnification.
What is the effect of soil erosion on water quality?
Increased sedimentation, which can cloud water, harm aquatic habitats, and carry pollutants.
What is the effect of deforestation on climate change?
Reduced carbon sequestration, increased greenhouse gas emissions, and altered regional weather patterns.
What is the effect of pesticide runoff on aquatic ecosystems?
Harm to aquatic organisms, disruption of food webs, and potential for biomagnification of toxins.
What is the effect of fertilizer runoff on drinking water sources?
Contamination with nitrates, which can pose health risks, especially to infants.
What is the effect of intensive agriculture on soil health?
Depletion of nutrients, loss of organic matter, reduced water infiltration, and increased susceptibility to erosion.
What is the effect of monoculture farming on pest populations?
Increased susceptibility to pest outbreaks due to the lack of biodiversity and concentrated food source.
What are the steps of eutrophication?
Excess nutrients runoff, algal blooms occur, algae die and decompose, oxygen depletion, aquatic life dies.
How does pesticide resistance develop?
Initial pesticide application, some pests survive, survivors reproduce, subsequent applications less effective, resistance spreads.
