Is the average ecological footprint getting larger or smaller globally? What will be an ideal response?
The average ecological footprint is growing. Most of the citizens of planet Earth live in developing

ecological footprint goes up (and Americans generally refuse to lower those), the strain on the Earth’s
limited resources increases.
