I just saw in The Daily Barometer here at OSU that there's a new engineering degree offered, Ecological Engineering.

I don't have a copy of the Barometer handy at the moment (and the web version is a day or so behind) but I seem to recall them saying this was the first of it's kind in Oregon.
So if you like nature, which I'm sure you do if you're on ifish, and your heading to college soon or are still undecided on your degree, this might be worth looking into.
