In an age when the environment is garnering more attention and global warming seems to be an increasingly popular topic, it is no surprise that iPhone apps are taking cues and beginning to focus on beloved Mother Earth. One such app, which turns recycling into a game, is i-Dig: The Recycling Challenge. The game is based on an ecological adventure in which the goal is to help a worm collect (and properly recycle) as much trash as possible. There are obstacles to amp up the excitement of rummaging and recycling, and the game also offers single and multi-player modes. At the end of the day, though, i-Dig is just reinforcing some eco-friendly habits which, let’s face it, we all need to adopt.
