envio-fascist
A) People who radically care about the current condition and outcome of the planet Earth.

B) People who wish to combat pollution, global warming,  toxic chemicals, and the use of non-renewable resources; 

Envio-Fascists can be seen daily recycling, cleaning up debris from the roadside and/or (but not limited to) beaches, rivers, and forrests.
They often use every ounce of their energy spreading their ideals of protecting our planet, and get angry when you litter.
(they may also support Al Gore)
