Don't see too many nutcases anymore.
There are the influential groups like Greenpeace and the Sierra Club. At the federal and state levels there are scientists and researchers and administrators within the the EPA who don't look anything like the Granola crunchers of the past.
Then there are the grassroots groups like "Stream Keepers" and "Trout Unlimited", both of which have openly voiced their disdain for development regardless of the steps taken to protect the environment.
The people wielding the political power are legit and seemingly unstoppable.
