Demi Moore and Ashton Kutcher headed to Guatemala to work with Habitat for Humanity on building houses for local organic farmers, inspired by Scout, Moore’s daughter with Bruce Willis. Meanwhile their other daughter, Rumer, made an appearance last week at a Power of Paws event in Manhattan, an animal-friendly initiative that promotes the benefits of bonding with pets. 

Celebs on the line: In Australia, an effort to hang clothes outside in the sun to dry, instead of using gas or electric dryers, is spearheaded by The Hills (not to be confused with MTV's [un]reality show). Hills makes a line of clotheslines for yards and apartments - an oldie-but-goodie idea that’s making a comeback, thanks to celebrity spokes-folks like singers Dannii Minogue and Olivia Newton-John, and actor Matthew Rhys (Brothers & Sisters). "Hang out your clothes to dry…not the planet," Says Rhys. FYI, electric dryers suck 6% of the total electric bill, second only to the fridge. Line-drying, on the other hand, is like tapping into solar power—without the costly panels.
