1. For each food item listed above, calculate the ecological footprint for the amount consumed and complete the last column of the table.

2. Calculate the total ecological footprint for an individual in the United States consuming all of these food items. How does this footprint compare with the world ecological footprint for food consumption, which is 0.9 ha per person per year?

3. Identify three ways in which you can reduce your personal ecological footprint for food consumption.
