ECO 324
Grand Canyon paper
Mengbo Han
26/11/2012

My idea is, we should forbid or reduce airline near or passed above Grand Canyon to protect the environment there.

The truth is, Grand Canyon has suffered from severe visibility problems, due in great part to pollution in the form of smog and haze. According to the final report of The Grand Canyon Visibility Transport Commission, the political body charged with looking into the issue,

"Research shows that visual air quality in the West experienced a significant decline due to emissions from industrial activity from the 1940s to the 1970s. Visibility-impairing emissions began to decline in the 1970s following enactment of the federal Clear Air Act. Visual air quality at national parks and wilderness areas on the Colorado Plateau has not appeared to change since reliable monitoring data became available in the 1980s."

This paragraph is not focused on the aircraft, but it does shows the air pollution in Grand Canyon is a serious problem.

Industry and transportation contribute the largest percentage of smog forming emissions; trans-border pollution from Mexico was also cited as potentially significant contributors.

For aircraft, it will certainly decrease the air condition. Aircraft create several types of air pollution. Pollution occur both at the airport during fueling, take off and landing and while the aircraft are in flight.

For example, aircraft would make more greenhouse air, carbon dioxide, nitrogen oxide and some water. Also, aircraft fuels contain some sulfur compounds. These are emitted as particulate. These particulates act as nuclei for cloud formation, when they have some reaction with water steam, there would be some low-concentration vitriol, which is bad for rock in Grand Canyon. Because of Hoover Dam, Grand Canyon has less water likes it used to have.

For rocks in Grand Canyon…...

Eco 360 Week 2 Simulation Paper

...Supply and Demand Simulation ECO/365 The simulation addressed many factors including supply and demand in the big picture of both microeconomics and macroeconomics. GoodLife Management is a company that manages rental complexes and has a monopoly of sorts in that it is the only company that rents at seven certain complexes. As Lintech, a new company moves to Atlantis an increase in the demand for housing causes some change in both prices and supply. A good example of one principle of microeconomics in the simulation is the concept of reaching equilibrium, where supply and demand (opposing forces) cancel each other out (Colander, 2010). When Lintech moves to Atlantis there is a sharp increase in which a surplus on the market caused a downward pressure on the price. At that time there was no shortage or surplus because equilibrium was reached. Another principle that demonstrates microeconomics is that of opportunity costs. During the simulation Lintech, a large company moves in to Atlantis which causes the demand for rentals to increase. Opportunity cost is essentially what you give up to attain what you desire (Colander, 2010). The concept of employees of Lintech needing to travel to and from Atlantis and giving up other things in order to either accommodate the travel time and expense or accommodate moving to the city of Atlantis to be closer to work brings to mind opportunity cost. A principle of macroeconomics that is shown in the simulation is when the......

...Economic Activities ECO/372 Principles of Macroeconomics June 24, 2013 Johnny Shull Abstract This paper will review and describe gross domestic product, real gross domestic product, interest rates, inflation and unemployment. This paper will also review the decrease in taxes, massive layoff, and the purchasing of groceries and how they affect households, businesses as well as the government. Everything what happens within an economy sets off a chain reaction whether its big or small. One negative reaction could lead to a whole line of negative reactions which impacts consumers, businesses, and the government and vice versa for the positive impacts. Economic Activities Gross domestic product (GDP) measures the complete market worth for products and services sold and bought by organizations and consumers within an economy in a years’ time. Nominal GDP is a form of real GDP but the difference is that nominal GDP creates room for inflation with in the economy. Interest rate is the percentage of added to an amount that has to be paid back but there are two kinds of interest rates which are nominal and real. Nominal interest rates are those that are inflated and cause your principle balance to be more than what it originally is. Real interest rate is the actual amount of what you would be repaying due to the inflation (Colander, 2010). Economic changes are measured in real GDP which reflects the market value of the products that are sold within the economy for......

...Supply and Demand Simulation Allison Mullen Microeconomics 365 March 11, 2013 Vilma Vallillee Supply and Demand Simulation Macroeconomics looks at the economy as a whole, concentrating on factors such as interest rates, inflation, and unemployment (Colander, 2010). It also studies economic growth and the government’s role to moderate the harm caused by recessions. During the simulation government intervened and tried to set a price ceiling on two bedroom apartments to provide homes for those that were struggling in hard economic times. The simulation also talked about population trends and how they affect decisions in the marketplace. For instance, an increase in population caused demand for two-bedroom apartments to increase, but a change in preferences caused demand to increase. Microeconomics focuses on individual people and individual businesses (Colander, 2010). It analyzes individual entities or activities such as supply and demand in the market, and the effects of behaviors and decisions. The simulation gave two examples of microeconomic behavior as it explained how individuals react when faced with decisions about how to spend their money. It also stated that Atlantis was considered a monopoly because it has no housing development competitors nearby. Their profit incentives lead them to raise prices and lower output in order to get the most out of consumers. In determining the rental rate for Atlantis tenants it is important to understand that......

Case Study: Algoa Bay fin fish farming project 4. Analysis and Policy Implications 5. Conclusion 1. Introduction The global level of fish stocks are on an overall decline due to overfishing. Areas within South Africa such as the Eastern Cape Province are considered to be the second greatest producing province of aquaculture commodities. Because of the rich aquaculture within the Eastern Cape, the Departments of Agriculture, Forestry and Fisheries, through various criteria based on a Strategic Environmental Assessment (SEA), have selected Algoa Bay within the Eastern Cape to introduce fin fish farming. The various fin fish that are intended to be farmed in this area are linked fishery exports that contribute approximately R411 million per annum in the Eastern Cape. Thus study intends to investigate the development proposal aimed at increasing the growth of the aquaculture industry within South Africa as well as conducting an investigation into the economic and environmental issues associated with the introduction of aquaculture within areas such as Algoa Bay. The objectives with the introduction of fish farms are to increase job creation within the area and more importantly to manage the dwindling stocks of wild fin fish. A cost and benefit analysis will be...

Week 2 Individual Paper Eco/372

...Week 2 Individual Paper University of Phoenix Principles of Macroeconomics ECO/372 Week 2 Individual Paper To understand the economy of a country, a person must understand the Gross Domestic Product. The Gross Domestic Product, or GDP, is an economic indicator that measures the total output of products and services of a country (Amadeo, 2014). The GDP includes all products and services produced by every company in that country (Amadeo, 2014). The Gross Domestic Product is separated into several components. One component used to measure GDP is nominal GDP. Nominal DGP indicates the absolute output of a country and is measured quarterly by the Bureau of Economic Analysis (BEA) and is the raw measurement that estimates price increases of products into the GDP (Amadeo, 2014). The BEA must adjust the estimates monthly when updates are received to remain accurate (Amadeo, 2014). Real GDP compares one country to another and is calculated by removing the effects of inflation on products and measures the increase in prices from a year to year (Amadeo, 2014). Real GDP will be lower than nominal GDP because a price deflator is used (Amadeo, 2014). The price deflator is determined by comparing the current-dollar ratio of a series to the corresponding chained-dollar value, and multiplying it by 100 (U.S. Department of Commerce Bureau of Economic Analysis website, 2009). Additional factors that affect the GDP are the unemployment rate, the inflation rate, and the interest rate...

...This document of ECO 372 Week 1 Discussion Questions consists of: 1.The United States is an example of pure capitalism. 2. Price ceilings and price floors have almost always been successful and seldom create a shortage or a surplus. 3. I have used the concept of opportunity costs this week. 4.I could explain what would happen to the price and quantity of a good or service if demand increased and supply decreased. (You do not need to quantify your response, simply use the terms increase, decrease, or it depends on the magnitude of the changes. Provide a scenario that might bring this about and use supply and demand curves for your explanation.) 5. Price is a poor way of rationing scarce resources. [This question needs to be addressed both from the prospective of a consumer (demand) and a provider (supply). The text defines a scarce resource as anything that commands a price.] 6. There are three types of unemployment. 7. The number one trading partners with the United States are Russia, Germany, and France. 8. A firm will maximize profits or minimize losses when they produce at a point where marginal costs equal marginal revenue. 9. Economic activity is not a zero sum game. Whenever trade takes place in a market without force or fraud both parties can win. 10. The law of demand states that demand increases as the price goes down. 11.

...it was scarce and therefore the manufacturing company would pass that higher price onto the retailers in order to make up for these extra costs. Conclusion There are many factors that create shifts in supply and demand such as: scarcity of a product/good, seasonal items, taxes, increase or decrease in income, technology, higher number of competitors producing a particular good, or simply people’s taste. Even though equilibrium is ideal, it is not always beneficial to our economy. Supply and demand shifts are necessary in order to keep the economy moving forward.

Economics Week 2 Paper

...Economic Factors Economics affects everyone on a day to day bases whether aware of this fact or not. Economics in a nut shell is the branch of study and knowledge concerned with the production, consumption and transfer and allocation of wealth. Specifically we will be looking at the branch of economics known as macroeconomics or the economy as a whole and globally. Every action that involves goods, services, and money affects the economy of a country or nation. Simple actions such as shopping or buying groceries can have a huge effect on an individual, business and governmental level. Other factors that have a huge effect on global economics are layoffs and unemployment, as well as government actions such as tax increases or decreases. Food is a necessity for the survival and ability for individuals to thrive. Buying groceries is a task that most have come to hate, but realize the need to continue this act. Every time a grocery cart is loaded, paid for and bagged the economy is affected. Households business and even government are affected by the production, distribution and purchasing of groceries. On an individual and house hold level, families have to budget for groceries. Food is dire for survival, but for some people living pay check to pay check obtaining food can become a constant worry over having the necessary funds. According to “USDA” (2015) “the food-at-home (Grocery store or super market food items) CPI was down 0.5 percent in March and is 1.9 percent......
