Click the link to get the full story. - Just FYI Mark --------------------------- Dirty water kills 5,000 children a day · Sanitation the key to saving millions of lives · UN urges governments to ensure supplies for all Ashley Seager Friday November 10, 2006 http://environment.guardian.co.uk/water/story/0,,1944323,00.html Nearly two million children a year die for want of clean water and proper sanitation while the world's poor often pay more for their water than people in Britain or the US, according to a major new report. The United Nations Development Programme, in its annual Human Development report, argues that 1.1 billion people do not have safe water and 2.6 billion suffer from inadequate sewerage. This is not because of water scarcity but poverty, inequality and government failure. The report urges governments to guarantee that each person has at least 20 litres of clean water a day, regardless of wealth, location, gender or ethnicity. If water was free to the poor, it adds, it could trigger the next leap forward in human development. Many sub-Saharan Africans get less than 20 litres of water a day and two-thirds have no proper toilets. By contrast, the average Briton uses 150 litres a day while Americans are the world's most profligate, using 600 litres a day. Phoenix, Arizona, uses 1,000 litres per person on average - 100 times as much as Mozambique (story continues) . . . . ------------------------------------------------------------------------ Cheap nano knowhow cleans arsenic from water Contaminated water that causes illness and fatal poisoning among millions of people worldwide has been made safe to drink using tiny particles created by nanotechnologists Ian Sample, science correspondent Friday November 10, 2006 http://environment.guardian.co.uk/water/story/0,,1944136,00.html Contaminated water that causes illness and fatal poisoning among millions of people worldwide has been made safe to drink using tiny particles created by nanotechnologists. Scientists at Rice University in Houston are adapting the technique to make it cheap and simple enough to use in developing countries such as Bangladesh, where 57 million people drink water from wells with dangerously high levels of arsenic. The discovery emerged after tests with precision-engineered particles showed they were 100 to 1,000 times more effective at stripping toxic contaminants from water than existing filters. The scientists have since used the findings to develop a cheap alternative for people to purify water in their own kitchens (story continues . . .)
