This is only tangentially related, but still:

When I was still at college, many ages ago, one of my lab partners lived in an all-female, mostly-vegan co-op, because it was cheap. I came to visit her one day to work on our project, and was informed by one of the vegans that their co-op had no TV, because TVs emit dangerous freon gases, which (as everyone knows) are bad for the environment. It took me a while to recover from that one.
