We are dealing with environment issues more then 20 years. Since 2012 we started mapping illegal dumps in Czech republic. In 2013 we formalized our initiatives under NGO Ukliďme Česko (Let's Clean Up The Czech Republic) and we started to organized (with Let’s Do It support) voluntary cleaning events all over the Czech Republic (and even in a few places outside of it :-). Since 2018 we are national organizers of World Cleanup Day in Czech republic.
