In less than 3 months, a major international city will likely run out of water
In Cape Town, South Africa, they're calling it "Day Zero" -- the day when the taps run dry. City officials had recently said that day would come on April 22. This week, they moved up the date to April 12. Cape Town is South Africa's second-largest city and a top international tourist draw. Now, residents play a new and delicate game of water math each day.
