The Brazilian NGO SOS Mata Atlântica launched a few months ago a campaign aiming to raise awareness on water conservation at domestic level. The campaign is entitled "xixi no banho" ("Pee in the shower": it is indeed one of the main advices given to citizens if they want to consume less water).
The campaign was a success in Brazil and is starting to expand at international level, thanks to an animated film which circulated widely on television and on the internet: http://www.youtube.com/watch?v=XZ_D....
