A crash course in changing the world.
I've chosen this video because it's about a project in my own country. It is about a local currency called "Chiemgauer". There are severals advantages of local currencies. For example it keeps the local business alive. The Chiemgauer is just as valuable as a euro. But only for three months. Then the Chiemgauer losing two percent of it's value. With this money social services are supported.
