Today, one fifth of the world's population is without access to safe drinking water and two fifths are without access to suitable sanitation facilities. For both these reasons, 1.8 million infants die every year.
As a result of the growing number of water-related natural disasters such a floods, Landslides, and tidal waves in recent years, over 200 million people are affected by these devastations and more than 50,000 people are losing their lives on average a year. In 2007, floods damaged broad areas of East, Southeast and South Asia, Africa, Caribbean and Latin America, and Oceania. It is worth noting that floods have beset not only developing but also developed countries, including the NK and central areas of the USA.
