So how can we help to begin to clean up our act? Before we can answer that question we must find your family's ecological footprint. Complete the reading assignment and then answer the questions in the exercise below.
As you can guess, our footprint is much too large and we all must reduce our footprint if we are to create a sustainable balance with the Earth's ecosystems.
Calculating Your Family's Ecological Footprint. Complete the calculation activity on the web site and record your metric footprint size.
Now comes the most important part of all!
How can we all reduce our ecological footprint?
Our goal is to reduce the amount of water, energy and materials that our families use so that others after us will have the same opportunities we did!
