Enviro-nut 

Crazy people that will put the environment before human life, and don't realize that "saving the environment" wont do us any good if you have killed us all off.

Person1: You should join me in the hug a tree parade, and help us stop evil SUV polluters!
Person2: Ya right, I'm not a enviro-nut!

Environati 

1. Any of various groups claiming special environmental enlightenment.

2. persons who claim to be unusually enlightened regarding the environment, climate change, or any new-age nature-based religion (usu. one that worships some kind of earth goddess) that serves as religious justification for extreme environmentalism.

3. The educated, fanatical, and self-righteous members within the larger environmentalist movement.

1. While most people agree that climate change is a real, man-made phenomenon, the Environati continually refuse to acknowledge the argument that cutting carbon to 1950s levels would plunge the world economy into a global depression.

2. The Environati is claiming another victory today after the city council agreed to tax the holy shit out of residents in order to fund construction of a light rail transit system that no one will ever use.

3. "The Environati was protesting genetically modified crops outside Safeway again today. I told one of them that going back to organic agriculture would result in the starvation of 2 billion people, but he just mumbled something about 'Frankenfood' and handed me a flier."
