Vincent Kartheiser: I Won't Have Kids For Environmental Reasons (VIDEO)

Vincent Kartheiser, who plays Pete Campbell on 'Mad Men' and does not own a toilet, appeared on MSNBC Wednesday afternoon to talk about his "green choices," which include avoiding driving, eating meat and having kids.

He said he stopped driving four years ago, when his car flooded and he found that taking the train instead "actually enriched my life. It made my life better to slow down a little bit and walk through the city."

Vincent talked about other choices he has made to minimize his impact.

"I've been a vegetarian for four years and I have chosen not to have children, which are both green choices in my life," he said. "I also xeriscaped my lawn."

Earlier this year, Vincent told UK's Observer that he does not own a toilet.

"I don't have a toilet at the moment," he said. "My house is just a wooden box. I mean I am planning to get a toilet at some point. But for now I have to go to the neighbours. I threw it all out."
