I just love this idea from TEARFUND:

This year, World Water Day (22 March) falls on the same day as Mothering Sunday.

It’s an opportunity to be reminded that many mothers will spend Mothering Sunday walking for hours to collect water for their families, or caring for children suffering from illnesses associated with poor sanitation and unclean water.

To mark Mothering Sunday, we’re launching a new action. We want to get 500 mothers to speak out and sign our letter to Gordon Brown.

Tearfund will arrange to deliver the letter in the week before Mothering Sunday. We believe this is the first time this has been done, so by taking part you’ll be making history.

Getting involved will take you seconds.

If you’re a mother – send us an e-mail to campaigning@tearfund.org with your name, the name and ages of your children and the town you live in.

If you’re a son or daughter – tell your mum about what we’re doing, and ask her permission to add her to our letter. Then e-mail us at campaigning@tearfund.org.
