For each activity, such as eating lunch or traveling to school, make as complete a list as you can of the resources and fuels that went into the activity and try to determine the impacts of using those resources. After completing your inventory, visit the website for the Global Footprint Network (http://www.footprintnetwork.org) and complete the personal footprint calculator. Compare the impacts you described with the impacts you are asked to identify in the personal footprint calculator. Write a reflection of this activity on the same page as your activities.
