Overview: In this assignment, you will complete a Nitrogen Footprint online activity(http://www.n-print.org) to learn about the nitrogen cascade and human effects of nitrogenpollution. Then, you will answer a set of questions (link located in Week 5) based on what youlearned. You must complete the online activity in order to answer the questions.Learning Objectives:1. Describe the ways in which human activity affects the nitrogen cascade.2. Explain how reactive nitrogen separately affects climate, air quality (smog), andwater quality.3. Discover your contribution to nitrogen pollution.4. Evaluate the importance of diet and food choices on nitrogen pollution.5. Describe ways you could reduce your nitrogen footprint.Grading Rubric:You will have the opportunity to earn a total of 60 points on this assignment. There are a totalof 25 questions, but you are required to answer only the appropriate 19 of them, depending onwhether you are currently an omnivore, vegan, or vegetarian. These questions are under theWeek 5 link in Canvas as a “quiz” titled “Assignment #4: Discover Your Contribution toRegional and Global Nitrogen Pollution”.Please be sure to complete these questions to receive credit for this assignment.These 19 questions are worth a total of 60 points, which is the maximum score you can earnon this assignment. Canvas may tell you that “you didn’t answer some questions” for thequestions we will ask you to skip. Just know that you are required to answer the appropriate 19questions (including the required three at the end) for the opportunity to earn full credit.NOTE: To receive full credit, you must correctly complete the arithmetic on this assignment,and show your work in a separate document you will upload to the appropriate place in Canvas.Before completing the Canvas test, you must first determine your personal nitrogenfootprint by following the steps below.2Instructions:There are two parts to this assignment. Please make sure to complete both Part 1 and Part 2• Part 1 requires you to calculate your nitrogen footprint using the following website:http://www.n-print.org.• Part 2 requires you to complete a “quiz” in Canvas AND separately upload your work sowe can grade your assignment.A. Calculating your Nitrogen Footprint1. You may use a calculator, Excel or equivalent for this assignment. However,you must show your arithmetic calculations to have the opportunity to earn fullcredit. You can either show your calculations in the text box, or you can uploadit as an image of your calculation sheet.2. Go to the Nitrogen Footprint calculator website: http://www.n-print.org3. On this website, go to About à Background on Nitrogen. Read this page fromtop to bottom. Skip the UVA Earth Week Expo video but make sure to watchthe Nitrogen Cascade video (8:41) and read the table below it.4. Then, go back over to the Home link (in the top menu), and click on the greenbox labeled “Calculate your N footprint using the original N-Calculator in Flash”.Your Flash player must be up-to-date.5. Go through the first few menusi. Select the language you wantii. Read the introductioniii. Choose units as US Customary (pounds, miles, feet)iv. Choose United States as your country6. On the right side of the page, you’ll see a graph of the average nitrogenfootprint of a person from the US. Note that below the bars is the percentcontribution of each category. You can select the small circle icon above the bargraph to see this footprint as a pie chart, which shows you the overallcontribution (in percent) of each category. From the pie chart, you can go backto the bar graph by clicking the little bar icon above the pie chart.7. Next, we are going to explore the absolute size of your annual nitrogen footprintin addition to the contributions to nitrogen pollution from each sector of your life.Click on the “Continue” button beneath the place where you chose yourcountry.8. Starting with Food consumption (then Housing, Transportation, andGoods/Services), read the information in the introduction to each section.9. Then, slide the bars to input data for each of the different activities in your life.After each section, click Continue to go to the next section.10. The default values on the bars that you see are for the average American. If youdon’t know the answer to one of the questions, use the average value (i.e. donot move the bars). If you move the bars accidentally and want to move themback to the average value, consult the tables at the end of this handout that listthe average values for a typical American in each of the categories.11. Make sure to read the info paragraph and input values for the rest of thecategories, Housing, Transportation, and Goods/Services.312. When you have completed all the sections (Food, Housing, Transportation, andGoods/Services), go to the Result menu and select United States again from thedrop down menu. You do not have to enter your email or click on the box thatasks if you want to stay informed, but you can if you want to (this is notrequired).13. Then click on the Compare and Modify Your Footprint button to see your annualN footprint compared to the national average.14. Write down your total annual N use (in lbs), as well as your N use for each of theFood, Housing, Transportation, and Goods/Services categories (record these inboth lbs and percent of total). You will use these values later when answeringthe questions.15. Then write down the total annual N use for an average American (in lbs), as wellas an average American’s N use for each of the categories (record these in bothlbs and percent of total). You will use these values later when answering thequestions.B. Exploring other food choicesIf you are an omnivore (you eat animal products, i.e. not vegetarian or vegan), answerquestions 1-4 below, then skip to questions 9 and 10. If you are a vegetarian or vegan,skip to questions 5-8, then continue on with questions 9 and 10.1. Imagine if you were to become a vegetarian, meaning you eat no meat orseafood, but you do eat milk, cheese, and eggs. To do this on the NitrogenFootprint Calculator, click the Go Back button from the Results section and goback up to the Food Consumption area. Slide all of the meat (poultry, pork,beef, and seafood) slider bars to zero. Note that when you slide the bar to anew value, wait a few seconds – it takes a few seconds for the N footprint bargraph on the right to rescale.2. Write down (manually or electronically) the new value for your FoodConsumption nitrogen use and Total nitrogen use as a vegetarian (in lbs; youcan add them up from the individual food, housing, transportation, andgoods/services bars). You’ll use these numbers later.3. Do the same thought experiment but this time become a vegan, meaning youeat no animal products at all (no meat, milk, cheese, or eggs). Slide all the meat,milk, cheese, and eggs bars to zero. Note that when you slide the bar to a newvalue, it takes a few seconds for the N footprint bar graph on the right torescale.4. Write down the new value for your Food Consumption nitrogen use and Totalnitrogen use as a vegan (in lbs).5. If you are an omnivore, skip to Question 9 and 10. For vegetarians and vegans:Imagine if someday you became an omnivore, meaning you eat meat andmilk/cheese/eggs. To do this on the Nitrogen Footprint Calculator, slide all of themeat (poultry, pork, beef, and seafood), dairy, and eggs slider bars to theAmerican average values that are in the tables at the end of this handout). Notethat when you slide the bar to a new value, it takes a few seconds for the Nfootprint bar graph on the right to rescale.6. Write down (manually or electronically) the new value for your FoodConsumption and Total nitrogen use as an omnivore (in lbs). You’ll use thesenumbers later.47. If you are a vegan, do the same thought experiment by becoming a vegetarian(eliminate all meat, but keep cheese, dairy, and eggs in your hypothetical diet). Ifyou are a vegetarian, do the same thought experiment by becoming a vegan(eliminate all meat, cheese, dairy, and eggs in your hypothetical diet). Note thatwhen you slide the bar to a new value, it takes a few seconds for the N footprintbar graph on the right to rescale.8. Write down the new value for your Food Consumption nitrogen use and Totalnitrogen use as a vegetarian or vegan (whichever one you are not in real life) (inlbs).9. All students resume here: Now go back to the main N Footprint website bypasting the URL into your browser (http://www.n-print.org). Click on the “YourN Footprint” tab, then click on the Reducing Your N Footprint link to read aboutsome ideas on what you can do to make a difference.10. Now, go back over to Canvas, complete the quiz under Week 5, and answer the19 required questions associated with this assignment.11. Make sure you calculate the arithmetic correctly for full credit.For reference, the N footprint of the average American (per capita) is on the follow
