Lazy landlady

I was cruising through some of my classmates posts when I read that someone hates their community. I strongly dislike my lazy landlady. It seems that instead of purchasing the proper recycling recepticals for sorting the recyclables she has resorted to chucking them in the garbage. Sometimes I think she does it on purpose to spite me because I am an enviro-sci student. My landlady talks the talk but doesn't walk the walk. My roommate too. I don't push them to do stuff. I prefer to lead by example and provide info when they ask me about it.

So how do I engage these people in a way that doesn't have them running to do the opposite out of spite? (haha actually that is my landlady's MO whether environemtally related or not.) Do I just walk away and try to be content knowing that the seed of being a bit more sustainable has been planted? With these two personalities--yeah that is probably the best course of action but my head says I should try a different tactic. Perhaps I need to use reverse psychology.
