Although she’s had some transgressions over the years — like allegedly taking a private jet to Obama’s inauguration — Alba deserves cred for the green nursery she built for daughter Honor Marie. In fact, her whole home is pretty green, outfitted with used furniture and accessories, non-toxic paint, and a saltwater pool. She shops at the farmers market, drives a Prius, bikes around Paris, bakes vegan cupcakes for her kid, and lends her support to a ton of worthy causes, like Johnson’s Clean Water Initiative. And did we mention she chose an all-natural hypnobirth?
