Several members of my extended family decided they would take the Ice Bucket Challenge, where each poured a bucket of ice water over his or her head and challenged others do the same or make a donation to fight ALS within twenty-four hours. Starting this week and running through the rest of October the 4Liters Challenge involves living on just 4 liters of water per day in an attempt to educate the general public about water poverty. That converts to just a little over 1 gallon of water a day. For most of us here in the U.S. water is in abundant supply, but for many people in third world countries water is in scarce supply and often not safe for human consumption. Considering that on average most Americans use more than 400 liters of water per day, using 4 liters per day is definitely a challenge; one that I would like to invite everyone to attempt. Taking the 4Liters Challenge won’t make for quite the photo op that the ice bucket challenge did, but it will certainly be a great opportunity to learn first hand how precious having clean, easily accessible water on a daily basis is.
