On this edition of "Earth Matters Monday" I am joined by my gal-pal, the Emmy Award-winning journalist and best-selling author Jenniffer Weigel. We're gearing up for a tag-team public event at the Climate Action Museum in Chicago on September 11th and in preparation for the program, we are talking about some of the basics of earth science, how important it is to keep the water supply chain as healthy as possible and what the challenges might be in taking too much, and not giving enough back in terms of environmental stewardship.
