Prior to beginning work on this discussion forum, view video  The Ecological Footprint Explained (Links to an external site.) . The ecological footprint is a tool for helping us to visualize the impacts we make on the environment. In this week’s class discussion, you will have the opportunity to learn more about how connected you are to the ecosystems and biosphere that you inhabit.

In a course-long project beginning this week, you will take on the challenge of lessening your impacts on the environment through reducing the size of your ecological footprint. Specifically, you will identify possible lifestyle changes that would reduce the amount of resources you use and/or the amount of carbon dioxide emissions that you produce. In a course-long experiment, you will determine whether or not it is possible to make a measurable difference in your environmental impact through a few simple actions in your daily life. The first step, of course, is to determine your ecological footprint right now. To do that, you will calculate three footprints: an overall ecological footprint that takes most of our daily behaviors into consideration; a carbon footprint that focuses on our daily carbon emissions that are contributing to global climate change; and a water footprint that assesses daily water use.

Part A: Ecological Footprint

Use the footprint tool from the web page What Is Your Ecological Footprint? (Links to an external site.) to calculate your ecological footprint. At every opportunity, please select the “add details to improve accuracy” option. At the end of the footprint activity, make a note of how many Earths would be required if everyone lived like you. Then click on “see details” to obtain the following information:

· Your ecological footprint, in global hectares (a hectare is about 2.5 acres).

· Your top three consumption categories.

· Finally, research some ways you might reduce your footprint, identifying a few specific ones that you might put into practice throughout the course.

Part B: Household Carbon Emissions Footprint

Next, use the Carbon Footprint Calculator (Links to an external site.) to calculate your household carbon emissions footprint. After answering all the questions,

· Make a note of your carbon emissions footprint in pounds. Is that above or below the average household carbon footprint in the US?

· Explore specific actions you might take to reduce your footprint. Which of them might be practical to undertake in the next five weeks?

Part C: Water Footprint

Finally, use the Water Footprint Calculator (Links to an external site.) to calculate your daily water footprint. After answering all the questions,

· Make a note of your gallons-per-day water footprint.

· Record the top three contributors to it.

· Scroll down the page to access a series of “Tips” buttons you can click on for advice on reducing your footprint. Again, make a note of some specific ideas you see that might be practical to implement over the next five weeks.

Discussion Post Requirements

Your discussion should include all the information you gathered about your consumption habits from your three footprint calculations, including all numbers with units.

Footprint Table

Copy the table above and paste into your post, then add your data for each category.  You can also access the Footprint Table here   Download Footprint Table here. Then, in a well-crafted post of at least 200 additional words, examine the numerical results of your three footprint calculations by answering the following questions:

· What did you learn that surprised you about your consumption habits?

· What lifestyle changes could you make that would reduce one or more of the three footprints? Propose a minimum of five. (These do not have to be the ones you use in this course-long project; over the course of the discussion, you may opt to select other ones based upon classmates’ recommendations. You will be recording your final choices for lifestyle changes in your Journal at the end of the week.)

· For each lifestyle change, which footprint would you be lowering? Discuss potential obstacles to making those changes, and then suggest ways you might overcome those obstacles.
