March, among other things, is also known as World Water Month, and if you'll be residing in the US during that time, you should keep an eye out for the UNICEF logo around town.
Tavis Coburn has worked with UNICEF and design studio Droga5 to create this years campaign for the Tap Project, a charity event being rolled out in participating restaurants and communities across North America. It gives you the chance to help the citizens of Third World Countries by funding the most basic of modern requirements; access to fresh, clean water.
All you have to do is pay $1 for your glass of tap water. If you would like to become part of the movement, visit the UNICEF page here, where lists of restaurants in your town or city will become available nearer the month.
And for those of us who live outside the USA, you can donate here.
