ZAKARIA: Now for our "What in the World" segment. First, there was the space race between the Soviet Union and the United States.</s>NEIL ARMSTRONG, AMERICAN ASTRONAUT: That's one small step for man, one giant leap for mankind.</s>ZAKARIA: Now two of the world's largest economies are engaged in, well, a toilet race. "What in the World?" That's right, the world's two most populous countries are vying to modernize and they are both making potties a national priority. India's prime minister Narendra Modi and China's president Xi Jinping have launched initiatives to usher in an era of improved public health and at the heart of it is more toilets. We take it for granted but 2.5 billion people around the world still do not have access to adequate sanitation according to the U.N. That's almost four out of every 10 people on earth. And the populations of India and China are the worst off. Over 770 million Indians don't have access to a toilet at home. Neither do 329 million Chinese, according to Water Aid. What does that mean? Well, if you have visited either country, especially India, you would have seen or smelled it. Indeed, more Indians have cell phones than toilets, according to India's census. So Prime Minister Modi is tackling the problem and has coined the superb mantra, "Toilets Before Temples."
