Calculate an individual’s carbon footprint, ecological footprint, and water footprint.
DefinitionCalculation should include recording an individual’s daily activity in a journal and using mathematics to determine the amount of carbon emitted by an individual’s activity over a given timeframe (e.g., day, week, lifetime).
- What do you throw away over a one week period?
- How much does the amount of beef you eat contribute to your carbon footprint?
- What are the countries of origin for your food during one meal at home?
- What is the carbon footprint of a box of macaroni and cheese (or ramen noodles, pizza, Big Mac)? How did the food get to you?
