The type of people who care about greenhouse gases and the rain forests and generally just wine about people who don't drive priuses. Tend to like the obsolete solar power technology.
E.g(1) Human:I just filled up my 5.0Litre or bigger engine(liter for U.S)with 60L of petroleum, then chopped down a tree to keep warm.
Enviro-emo: Oh no how could you, don't you know what effect that has on the environment.
E.g(2)I love Priuses I am an Enviro-emo I think I'll go get as much attention as I can by bitching abount people that drive reasonable cars.
