| Agricultural production is highly dependent on inorganic substances including fertilizers. High-yielding crop varieties, such as corn, require large amounts of primary nutrients including nitrogen, phosphorus and potassium. Farmers often add a surplus of nutrients to crops to maximize yields. Utilization of primary nutrients has increased by more than 300% while that of nitrogen alone has increased by more than 600% between 1960 and 2007 (USDA, 2009). From 1964 to 2007, the use of nitrogen in the corn sector alone increased from 1,623,000 to 5,714,000 nutrient tons (USDA, 2009). While increasing production, increased fertilizer use can potentially create negative externalities in the form of nitrate-nitrogen contamination in groundwater.... |

| Economists, ecologists, private industries and government decision-makers have long been interested in the relationships between economic growth and environmental quality. These relationships are often the subject of intense public policy debates such as the current debate surrounding global climate change issues. From an ecological or environmental perspective, the argument is often made that economic growth is bad for the environment. But, what story do the data tell? In order to address the question, a estimable model was used to analyze the effects between gross domestic product (GDP) and environmental indications for air pollution in over 100 metropolitan statistical areas in the United States from 2001-2005. The analysis is then expanded to... |
