Imagine you wish your country totally clean, 50K people helped and tons of garbage is gone in one single day! This happened to Rainer Nolvak in Estonia. This year 94 countries are in. Annette Dölle is initiator at Keep It Clean Day! On the 21st of September the country will be cleaned from all litter and trash and you can help to make it happen! Annette speaks at the DIY Conference about organizing this massive clean up, obstacles, culture issues, activating people and getting them enthusiastic.
