In honor of Earth Day, take a step toward making your iPhone a little easier on the planet by dressing it in some eco-friendly gear. We gathered cases made of bamboo, the fastest growing wood on the planet; cork, which can be harvested without cutting down the cork oak tree; and biodegradable plastics to use with your phone for less tech impact on the environment.
