I see no need to reinvent the wheel here, so let me point you immediately to
PLU's ENVT links, where you may find all sorts of information about environmental organizations, internships, and graduate degrees in Environmental Studies. I must give a plug here to my own graduate program in
Environmental Studies at the University of Montana. One of the great moments (of many) for me while I was a student in Missoula occurred when I discovered the newspaper/magazine,
High Country News, where great writers deal bi-weekly with complicated social, cultural, and environmental issues facing the West. If you want to get your finger on the pulse of life in Western America, the best thing to do is to spend lots of time here, travel around, and pay attention. The next best thing is to read HCN. Folks affiliated with my other graduate alma mater, the University of Colorado, have produced a number of
interesting studies related to environmental issues in the West. In other parts of the country, countless people are working for environmental and social justice issues. The first organization I joined back in the 1980s, Save Our Cumberland Mountains, has
mission, values and vision statements worth noting. Meanwhile, the Everglades Foundation strives (with the help of a really interesting group of
board members) to protect America's most threatened wilderness, which happens to be one of my favorite areas of the planet.
