As Southern California experiences another water crisis, an awareness campaign meant to convince residents to reduce waste inevitable--and let's hope it's something better than, "If it's yellow let it mellow" this time. Here's one good option: Rethink Your Green , which targets the lush lawns and landscaping that is estimated to use 60% of available water in the state. The designers, finalists in the INDEX: AIGA Aspen Design Challenge, target the traditional, emotional needs for having a lawn.
Designers: Manuel Garcia; Eileen Hsu; Pouya Jahanshahi; Masato Nakada; Michelle Park and Maece Seirafi-Najar of California Institute of the Arts (CalArts)
