Identify one method used in the Green Revolution to increase crop production.

The use of synthetic fertilizers and pesticides was a key method to boost crop production during the Green Revolution.

100

What is the main purpose of irrigation in agriculture

Irrigation supplies water to crops for optimal growth

100

What are the main categories of pesticides and what are they used to eliminate or control?

Herbicides - plants

Rodenticides - rodents

Insecticides - insects

100

What is the primary concern regarding antibiotic use in livestock?

The overuse of antibiotics in livestock can lead to antibiotic-resistant bacteria.

100

What is bycatch, and why is it a concern in commercial fishing?

Bycatch is the unintended capture of non-target species during commercial fishing, raising ecological concerns.

200

How has mechanization in agriculture contributed to climate change?

Mechanization has increased agricultural efficiency but also contributes to carbon emissions.

200

Explain the concept of cone of depression in aquifers.

A cone of depression occurs when excessive groundwater pumping lowers the water table, potentially drying nearby wells

200

Describe the pesticide treadmill and its impact on pest populations.

The pesticide treadmill occurs when pests evolve resistance to pesticides, leading to the need for stronger chemicals.

200

Identify two benefits of CAFOs in meat production.

CAFOs are praised for their efficiency and ability to meet high demand for meat.

200

Describe what is meant by "fishing down the food web.

Fishing down the food web describes the practice of shifting fishing efforts to smaller species after depleting larger fish populations.

300

Describe one environmental disadvantage of using synthetic fertilizers in agriculture.

Synthetic fertilizers can increase crop yields but also contribute to nutrient runoff and water pollution.

300

What is the primary benefit of using furrow irrigation compared to other methods?

Furrow irrigation channels water directly into small trenches along crops, reducing water loss compared to other techniques.

300

Identify one method of integrated pest management (IPM) and its effectiveness

Integrated Pest Management (IPM) combines biological, chemical, and cultural methods for effective pest control.

300

Describe the concept of overgrazing and its consequences on soil health

Overgrazing occurs when livestock consume too much vegetation, leading to erosion and poor soil health.

300

What are the negative impacts of bottom trawling on marine ecosystems?

Bottom trawling involves dragging nets along the ocean floor, harming habitats and biodiversity.

400

What are High-Yield Variety (HYV) crops, and how do they differ from traditional crops?

High-Yield Variety (HYV) crops were developed to produce higher yields than traditional crops and often require more inputs like fertilizers and pesticides.

400

Describe how overwatering can lead to soil salinization

Overwatering can lead to soil salinization, the accumulation of salts in the soil, harming plant growth.

400

What role do GMOs play in pest management, and what is a potential risk associated with their use?

GMOs can resist pests but may lead to concerns about genetic contamination.

400

What are the greenhouse gas emissions associated with meat production, and how do they compare to plant-based diets?

Meat production releases methane and carbon dioxide, which contribute significantly to global warming, especially compared to plant-based diets.

400

Explain the concept of "Tragedy of the Commons" in the context of overfishing.

The Tragedy of the Commons describes how shared resources are overused, such as in the case of overfishing.

500

Explain how the Green Revolution has impacted global food supply and one negative consequence associated with it.

The Green Revolution greatly increased global food supply but also led to issues such as pesticide resistance and soil degradation.

500

Compare and contrast drip irrigation and flood irrigation in terms of efficiency and impact on soil health

Drip irrigation minimizes water use while flood irrigation can lead to waterlogging, differing in efficiency and impact on soil health.

500

Discuss the benefits and drawbacks of using biocontrol methods in pest management

Biocontrol uses natural predators to control pests but can sometimes disrupt local ecosystems

500

Evaluate the environmental impacts of Concentrated Animal Feeding Operations (CAFOs) versus free-range grazing.

CAFOs contribute to deforestation and pollution, while free-range grazing requires more land but has lower emissions.

500

Propose a solution to address fishery depletion and discuss its potential effectiveness.

Implementing marine reserves and catch limits can help address fishery depletion and protect global fish stocks.
