Exactly my point, on urban planning. As for the environmental sciences grad, she wasn't going into environmental sciences as a career field. She was looking into geographic information systems--which is not exactly a "fluff" field either.
They are the ones who draw up maps of cities and counties for emergency services and the like, to show "best/quickest routes" for fire/ambulance/police first-responders.
They also do disaster evacuation planning for cities and counties. My in-laws do this for Pierce County in Washington state. During flood season, they've had to draw up computer models for how the area is likely to flood, and show the best routes for evacuation should the river in the area exceed its banks by X amount.
16 dead and 20 missing and it's dollars to doughnuts the flood danger areas hadn't been marked in 21 years.
