I am a professional hydrologist who retired from his 'day job' following a 37 year career as a principal investigator, supervisor, and manager with the U.S. Geological Survey. Teaching provides me an opportunity to give back to the profession and to inform students about the critical role that earth science plays in their daily lives. It is critically important to understand the dynamics of our planet, its natural processes and their interactions. As informed citizens, we need to insist upon the application of sustainable human activities acceptable within the physical limitations of our environment that insures health and prosperity as individuals, as a nation, and as a global community.
