Review for Quarterly

Tragedy of the Commons

The depletion or degradation of shared resources due to individuals acting in their self-interest, disregarding the common good.

Sustainability

Meeting present needs without compromising the ability of future generations to meet their own needs.

Green Revolution

Period of increased agricultural productivity through the adoption of high-yielding crop varieties, modern farming techniques, and chemical inputs.

Genetically Modified Crops

Advantages include increased crop yield and resistance to pests and diseases, while disadvantages include environmental concerns and potential harm to non-target organisms.

Environmental Impacts of Farming

Land impacts include soil erosion, deforestation, and loss of biodiversity, while water impacts include pollution, aquifer depletion, and altered water flow.

Tilling Methods

Conventional tillage, conservation tillage, and no-till, with impacts including soil erosion, compaction, and disruption of soil structure.

Irrigation Methods

Drip irrigation, flood irrigation, and sprinkler irrigation, with benefits of increased crop yields and water efficiency, but drawbacks of water wastage and soil salinization.

Water-intensive Foods

Beef, almonds, and rice require the most water to produce, while fruits, vegetables, and legumes require the least.

Ogallala Aquifer

Located in the central U.S., it is being depleted faster than it's being recharged due to excessive water use in agriculture.

Pesticide Resistance

Pesticide use can lead to the development of resistant pests, reducing the effectiveness of the pesticide over time.

Concentrated Animal Feeding Operations (CAFOs)

Benefits include increased efficiency and higher production, but drawbacks include environmental pollution and animal welfare concerns.

Antibiotic Use in CAFOs

Can lead to antibiotic resistance, affecting human health.

Meat Consumption

Generally, industrialized countries have higher meat consumption per capita compared to developing countries.

Greenhouse Gas Emissions

Raising cattle, especially beef, generally results in higher emissions compared to poultry and pork.

Free Range Grazing

Benefits include improved animal welfare and potential environmental benefits, but drawbacks include lower efficiency and land use concerns.
