We are making a smart phone app that is called Cleaner. The app will show you a map of your surroundings. In this online map you will see where in your neighborhood lies plastic trash. If you cleaned it up you can send a video/photo of the collected trash, and if you cleaned it up you get a online medal. If you have many medals you can collect prizes that have something to do with nature.
