a) Identify and describe a human health condition that arises from food or vitamin deficiencies

One human health condition that arises from food or vitamin deficiencies is iron-deficiency anemia. Iron is an essential mineral that helps red blood cells carry oxygen throughout the body. When the body doesn't get enough iron, it can't make enough healthy red blood cells, leading to anemia.

Anemia can cause fatigue, weakness, shortness of breath, and other symptoms. It can also increase the risk of infection and other health problems.

b) Describe one advantage and one disadvantage to using genetically modified organisms as crops and food sources

One advantage of using genetically modified organisms (GMOs) as crops and food sources is that they can be engineered to be more resistant to pests and diseases. This can lead to higher yields and lower food costs.

One disadvantage of using GMOs is that they could potentially have unintended environmental consequences. For example, GMOs could cross-pollinate with wild plants, leading to the spread of modified genes into the environment. This could have negative impacts on biodiversity and ecosystems.

c) Discuss the connection between meat production and air pollution

Meat production is a major source of air pollution. The process of raising livestock, especially cattle, produces large amounts of methane, a greenhouse gas that is more potent than carbon dioxide. Methane is released from the digestive systems of cows and other ruminants, as well as from manure lagoons.

In addition, the transportation of livestock and meat products also contributes to air pollution.

d) Explain and describe one environmental and societal disadvantage to using conventional pesticides

One environmental disadvantage of using conventional pesticides is that they can harm beneficial insects, such as bees and butterflies. This can lead to a decline in biodiversity and ecosystem health.

One societal disadvantage of using conventional pesticides is that they can pose a risk to human health. Pesticides can be absorbed through the skin, inhaled, or ingested, and can cause a variety of health problems, including cancer, birth defects, and reproductive problems.

e) Name a US federal agency that is responsible for regulating pesticide use in some way. Identify one federal law associated with assessing health effects or allowable limits of pesticide products.

The US Environmental Protection Agency (EPA) is responsible for regulating pesticide use in the United States. One federal law associated with assessing health effects or allowable limits of pesticide products is the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).

FIFRA requires the EPA to review and register all pesticides sold in the United States. The EPA assesses the health and environmental risks of each pesticide before it can be registered for sale.

FRQ 2

a) identify and explain two environmental impacts food production has on the ecosystem

b) discuss one pro and one con concerning the use of aquaculture to produce more food

c) explain what integrated pest management (IPM) is and a disadvantage to this method

d) other than IPM identify two environmentally sustainable agricultural practices to food production

and one more federal law for the last question E

a) Identify and explain two environmental impacts food production has on the ecosystem.

Habitat destruction: Clearing land for agriculture can destroy natural habitats, leading to loss of biodiversity. Water pollution: Runoff from agricultural fields can contain fertilizers and pesticides, which can pollute waterways and harm aquatic life. b) Discuss one pro and one con concerning the use of aquaculture to produce more food.

Pro: Aquaculture can help to reduce overfishing of wild fish populations. Con: Aquaculture can contribute to water pollution and the spread of disease. c) Explain what integrated pest management (IPM) is and a disadvantage to this method.

IPM is a pest control strategy that uses a combination of methods to manage pests, including biological, cultural, and physical controls. IPM can be more expensive and time-consuming than using pesticides.

d) Other than IPM, identify two environmentally sustainable agricultural practices for food production.

Crop rotation: Planting different crops in the same field each year can help to improve soil health and reduce the need for pesticides. Cover cropping: Planting cover crops between growing seasons can help to prevent soil erosion and improve soil fertility.

I. Introduction

The early 19th century saw growing tensions between the North and South, caused by economic differences and disputes over the institution of slavery. The North’s industrial economy increasingly opposed slavery, while the South’s reliance on enslaved labor caused it to defend the practice as essential to its way of life. Although early compromises, such as the Missouri Compromise of 1820, temporarily eased these tensions, they failed to resolve the fundamental causes of sectional conflict. By the 1830s, debates over slavery’s expansion and morality caused further division, bringing the nation closer to war.

Debates over slavery from 1830 to 1860 significantly escalated tensions that led to the Civil War by exacerbating sectional divisions through political compromises, the rise of abolitionism, and violent confrontations. These debates not only shaped national policies but also entrenched irreconcilable differences that made conflict inevitable.

II. Body Paragraphs

A. Political Compromises and Their Failure (Causation)<br /> Topic Sentence:<br /> Political compromises aimed at addressing slavery's expansion highlighted the deep divisions between the North and South, ultimately failing to prevent conflict.

Evidence:<br /> - The Compromise of 1850: Temporarily eased tensions by admitting California as a free state and strengthening the Fugitive Slave Act, angering both sides.<br /> - Kansas-Nebraska Act (1854): Repealed the Missouri Compromise, introducing "popular sovereignty," which led to "Bleeding Kansas."<br /> - Dred Scott Decision (1857): Declared African Americans could not be citizens and nullified the ability of Congress to restrict slavery in territories, enraging abolitionists and empowering Southern slaveholders.

Explanation:<br /> These attempts at compromise failed to address the root causes of sectionalism, instead intensifying disagreements over slavery.

B. The Rise of Abolitionism (Change Over Time)<br /> Topic Sentence:<br /> The growing abolitionist movement transformed slavery from a regional to a national moral crisis, heightening tensions.

Evidence:<br /> - William Lloyd Garrison’s The Liberator (1831): A radical abolitionist newspaper that galvanized Northern opposition to slavery.<br /> - Frederick Douglass’s speeches: Spread awareness of the brutality of slavery and mobilized public opinion.<br /> - Harriet Beecher Stowe’s Uncle Tom’s Cabin (1852): Influenced public sentiment in the North, portraying the moral evils of slavery.

Explanation:<br /> Abolitionism broadened the ideological divide, with the North increasingly viewing slavery as immoral, while the South defended it as essential to their way of life.

C. Violent Confrontations (Causation and Comparison)<br /> Topic Sentence:<br /> Violent events during this period underscored the inability to resolve the slavery issue through political means and set the stage for war.

Evidence:<br /> - Nat Turner’s Rebellion (1831): Heightened Southern fears of slave uprisings and led to stricter laws.<br /> - "Bleeding Kansas" (1854-1856): Violent clashes between pro-slavery and anti-slavery settlers demonstrated the failure of popular sovereignty.<br /> - John Brown’s raid on Harpers Ferry (1859): Intensified Southern fears of Northern aggression and abolitionist conspiracies.

Explanation:<br /> These violent episodes revealed that slavery was not just a political issue but one that provoked life-and-death struggles, making compromise increasingly unviable.

III. Conclusion

A. Restate Thesis:<br /> From 1830 to 1860, debates over slavery deepened sectional tensions by exposing the failure of political compromises, the polarizing impact of abolitionism, and the escalation of violence, ultimately leading to the Civil War.

B. Complexity:<br /> On the other hand, some might argue that economic differences or states' rights, rather than slavery itself, were the primary causes of the Civil War. However, slavery was inextricably tied to these issues, as Southern economic dependence on slavery and its insistence on protecting the institution under states' rights proved central to the conflict.
