Burning Man Festival began all the way back in 1986 as a small get together but now it is so much more. Along with being one of the biggest festivals in the world, it also boats 10 key principles, one of these being that there should be no physical traces left of the festival. This means that every festival is cleaned up after by their own guests using the MOOP map, as well as guests being told to take any rubbish they bring, home with them.
Wouldn't it be amazing if you could incorporate an idea like this at your event?
Or your daily life, by always making sure, whatever you are doing, the area around you looks the same, or better, by the time you leave?
