I understand Ryan's quote, and think it's a good one. Move to a city or college town, and you'll understand.
The environmentalists sit at drum circles (probably playing the music we talked about in the other thread.
![Stick out tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
) and talk hypotheticals.
Let's break the two words down here.
They both have the "ism" suffix:
http://en.wikipedia.org/wiki/-ism
Other than that, there are the root words: Environment and Conserve.
They are both a philosophy, but given that "conserve" is a verb, it is also falls into the "action, process..." area. Conservationism mandates action. All environmentalism takes is a little bit of hot air.
That's my hot air on the subject.
Keeping in mind that I'm clearly joking about the "drum circles" comment. There are many faux environmentalists that do just that though.
