阅读理解 Far more people in India have access to a mobile phone than to a toilet, according to a UN study. India's mobile users totaled 563.73 million at the last count, enough to serve nearly half of the country's population. But just 366 million people-around a third of the population-had access to proper sanitation (卫 生设施) in 2008, said the study published by the UN University, a UN thinktank. 'It is a tragic irony (讽刺) to think in India, a country now wealthy enough that roughly half of the people own phones, so many people cannot afford the basic necessity and quality of a toilet, ' said UN Univers ity director Zafar Adeel. Adeel heads the UN University's Institute for Water, Environment and Health, based in the Canadian city of Hamilton, which prepared the report. Worldwide, an estimated 358 billion dollars is needed between now and 2015 to achieve the UN Millennium Development Goal (MDG) of halving the proportion of people with inadequate (不充分的) sanitation from 2000 levels. 'Proper san itation could do more to save lives, especially those of young people, improve health and help pull India and other countries in similar circumstances out of poverty than any alternative investment, ' Adeel said. Poor sanitation is a major contributor to waterborne diseases (水传播疾病), which in the past three years alone killed an estimated 4.5 million children under the age of five worldwide, according to the study. The report gave a rough cost of 300 dollars to build a toilet, including labour, and materials.The world could expect a return of up to 34 dollars for every dollar spent on sanitation through improved productivity and reduced poverty and health costs, said Adeel.He said improving sanitation was an economic and humanitarian opportunity of historic proportions. 1.
