Ever hear of developers muttering about getting medieval on some pointy headed environmentalist who held up construction of a gadzillion dollar dam because of some slimy fish that was on the endangered species list?
That pointy-head has power, an ecologist type who can halt construction dead.
Assuming they're honest, that is. Rumor has it that construction and engineering firms have ecologists in their employ who will investigate sites for environmental worthiness and basically tell their employers what they want to hear.
The site's environmentally sound, the ecologist assures the boss.
