The link between geology and human health may not seem obvious, but it many ways geology can affect public health in a variety of crucial ways. Certainly, the relationship between geological factors and water and air quality is one that continues to interest policy makers and others. This site explores these issues, and it was created by the people at Carleton College's Professional Development for Geoscience Faculty initiative. Here visitors can make use of a wide range of educational and supporting materials, including classroom activities, key visualizations, and collections of external links. First-time users may wish to start at the "Resources for Educators" area, which includes a brief overview titled "Essential components of geology and human health" and several helpful posters. The remaining materials can be viewed in sections that include "Bookshelf", "Visualizations", and "Internet Resources".
