Contaminated drinking water is the biggest cause of death and disease in the world. You can help solve this huge problem by carrying an (empty) bucket in the 5 km Charity Challenge. This is the same distance women and children carry (full) buckets in in the developing world. Sign up for the 5 km Charity Challenge at https://secure.eventsonline.ca/events/crs_scotia/. Get friends to join you. Get sponsors. World developmental economists rank 'giving clean water to rural villages' the most effective use of donor dollars. Let us all do our part.
