Help save the earth a little at a time. Here's a really easy and fun way to do just that. Old Navy stores are taking your old flip-flops and giving them to TerraCycle, who in turn recycles them into Playground sets. Here's a video about what TerraCycle does and how they re-use everyday garbage. I was just thinking about purging my old worn out ones from the summer but haven't gotten around to ditching them yet. Good thing I didn't. Now I can put them to better use!
