Tomorrow, Wednesday, March 22nd, is World Water Day. 11 marches (sponsored by Ethos Water and Starbucks) will take place is the USA.
The idea is to remind us in developped countries that many people(most often women) in the world have to walk as much as 6 miles to get to a water source.
If you cannot join one of the walks, you can sign up as a virtual participant. Tell your friends and spread the word on your website or blog.
I read about it on the Ted Blog today
