Check out the EPA's official web site at
http://www.epa.gov/, or the
Department of Interior's web site. These two sites have many great links. Then try a state environmental agency's site, such as
Oregon's Department of Environmental Quality.
Ohio's Department of Natural Resources is also very useful.
Another site to look at is one created by
Alaska's Department of Environmental Conservation that, at one point, was selling authentic oil samples from the Exxon Valdez spill.
The web pages of environmental organizations such as the
Sierra Club, the
National Wildlife Federation, and the
Nature Conservancy provide a wealth of information about the environment and natural resources.
