Even though Earth Day is over, you can still help the planet by doing something that they already do—shop! While setting out on spring shopping this April, you can participate in nationwide recycling programs in Geneva by bringing used flip-flops to Old Navy. Through May 21, shoppers of Old Navy can deposit their used flip flops in colorful collection bins found inside any Old Navy store. TerraCycle will then recycle the flip-flops into playgrounds which will be donated to communities around the country.
