Maria, Josh, Laura Activity 1: Carbon Cycle 1. Identify 3 ways you are having an impact on the carbon cycle by increasing carbon in the atmosphere. a. I am having an impact by driving, using the heater in my dorms, and using pencils. 2. Think about which changes in your life would be the easiest ones to make to reduce this impact, and which changes would the most difficult. a. Using public transportation would be the hardest and switching to something else to write notes would be the easier one. 3. Identify ways that government, business, personal connections, and other outside factors could make these changes easier for you to make. a. The government could make stricter policies in burning fossil fuels for factories and make people go electric for their transportation. A lot of factors are out of our control but the small things we can change/ switch we should to make a not-so-harren carbon impact. Activity 2: Nitrogen Pollution 1. What share of the nitrogen pollution into Chesapeake Bay is contributed by agriculture? a. 38% is contributed by agriculture 2. What is the largest source of nitrogen air pollution? a. Vehicles and powerplant industry 3. According to Figure (b), changing practices in which sector provides the cheapest nitrogen reduction strategies? What is the cost per pound of nitrogen saved? a. Restored/constructed wetlands. It is about $1.50 per pound 4. How does the percentage of nitrogen coming from natural sources compare to that from a) agricultural sources? b) wastewater treatment and other urban/suburban sources? a. 48% agricultural b. 46% wastewater 5. Considering what you have learned, name at least one source of nitrogen pollution that is not addressed by the reduction strategies in Figure (b). a. Algae blooms create an increase in nitrogen pollution and can cause a lot of fish and other plants to die 6. Consider the cost per pound of the different strategies in Figure (b). Overall, do natural solutions or human-engineered solutions cost more? Support your answers with data from the Figure. a. I would say that natural solutions cost less. It takes a lot more for humans to restore something that shouldn’t have been messed with in the beginning. 7. Given the sources in Figure (a) and the reduction strategies in Figure (b), what strategies do you recommend communities in the Chesapeake Bay area do to reduce nitrogen in the bay? Imagine you are a consultant hired to prepare recommendations for what should be done and who should do it. Make your case using the figures and information you have learned to support your position.

a. With the information given, I’d say that stormwater is very expensive but also accumulates a lot of Nitrogen as well. I’d advise the Chesapeake Bay to find out how to exclude nitrogen from causing emissions to stormwater
