I always enjoy reading from the extreme sides of an issue in toward the middle. I suspect that reality usually lies somewhere in between extreme viewpoints, so I like to tackle issues by reading from the outside in.
It helps to know what both sides are shouting about (and convenently ignoring) when trying to find that elusive rascal called truth. For example, I regularly listen to both Sean Hannity (far right on just about everything) and Keith Olbermann (far left on just about everything). I also always read Charles Krauthammer (right wing writer for the Washington Post) and Paul Krugman (Princeton economics Professor, recent Nobel prize winner and New York Times writer who is usually to the left of things).
Personally, I don't completely agree with any of these people, but understanding their perspective helps me figure out my own. I definitly agree with some of these guys more than others by the way, and on some issues more than others, but being a good, objective instructor of economics, I'm going to keep that bit of information to myself. ;)
In EVS/ECN 330 we've been talking about trash and recycling (CERMES students should be reading that lecture about this same time), so here are a couple of opposing viewpoints to consider:
In the right corner we have PERC (Property and Environment Research Center)
In the left corner we have EDF (The Environmental Defense Fund)
