"As long as we must choose between present comfort and future climate, there can be no joy!" So declares Mr. Sustainable, as he searches for a way to feel good while doing good. In this before and after, can new advances in ultra light winter wear and "fresh perspectives on intergenerational relationships" help Mr. Sustainable and his spouse end a long, tense period of thermostat wars? Actors are Steve Hiltner, Basha Parmet and Cheryl Jones. Performed in wintry march at the Princeton Public Library as part of the Princeton Environmental Film Festival.
