The World Health Organization (WHO) reports that as many as 2.5 billion people around the world do not have access to adequate toilet facilities.
Poor sanitation results in contaminated drinking water and the spread of infectious diseases including Cholera and Dysentery, which cause severe diarrhoea, dehydration and if left untreated, death (see my blog, ‘Everyone should have a human right to water’).
Every year, around 1.5 million people – mostly children under five years old – die from diarrhoea. Drastic action is needed in order to make safe sanitation accessible to all.
Only last week, I observed that we sometimes have a tendency to take things for granted in the developed world. My blog, ‘Chemical engineer develops sanitary towels to help girls stay in school’ was well received and has prompted me to look at some other work by chemical engineers who are making a difference in the developing world.
