All Flashcards
How can no-till farming help protect the environment?
Reduces soil erosion and improves soil health.
How can crop rotation help protect the environment?
Helps maintain soil fertility and reduces pest problems.
How can integrated pest management (IPM) help protect the environment?
Uses a combination of methods to control pests while minimizing the use of pesticides.
Define slash and burn agriculture.
Cutting down vegetation and burning it to clear land for farming.
Define tilling.
Turning over the soil to prepare it for planting.
Define fertilizers.
Substances added to soil to promote plant growth.
Define pesticides.
Substances used to kill pests.
Define herbicides.
Pesticides that kill plants (weeds).
Define insecticides.
Pesticides that kill insects.
Define rodenticides.
Pesticides that kill rodents.
Define eutrophication.
Excess nutrients in water bodies causing algal blooms.
Define biomagnification.
Toxins become more concentrated as they move up the food chain.
Define no-till farming.
Agricultural technique that reduces soil erosion and improves soil health.
What are the environmental consequences of slash and burn agriculture?
Deforestation, soil erosion, and air pollution.
What are the environmental consequences of tilling?
Soil erosion, loss of nutrients, disrupted soil microbes.
What are the environmental consequences of fertilizer use?
Eutrophication, dead zones, water contamination.
What are the environmental consequences of pesticide use?
Harm to non-target species, pesticide resistance, human health issues.
What is the effect of soil erosion on waterways?
Increased sedimentation, which can harm aquatic ecosystems.
What is the effect of algal blooms on aquatic life?
Depletion of oxygen, leading to the death of aquatic organisms.
What is the impact of deforestation on biodiversity?
Loss of habitat and reduced biodiversity.
What is the effect of pesticide use on human health?
Can cause cancer, birth defects, and neurological problems.
What is the effect of tillage on carbon sequestration?
Reduced carbon sequestration in soil.
What is the effect of fertilizer runoff on water quality?
Contamination of drinking water sources.
