Answer:
Some 650 million people, or one in 10 of the world's population, do not have access to safe water, putting them at risk of infectious diseases and premature death.
Dirty water and poor sanitation can cause severe diarrhoeal diseases in children, killing 900 under-fives a day across the world, according to United Nations estimates - or one child every two minutes.
Among newborn babies, the World Health Organization says infections caused by a lack of safe water and an unclean environment cause one death every minute somewhere in the world.
The U.N. says access to safe drinking water and adequate sanitation services is vital to human health.
According to a UN estimate, by 2025 more than half of the world's nations may be seriously short of fresh water. By the middle of this century, this figure may rise to three-quarters
Even today, one of six people, or more than a billion people worldwide, are short of fresh water to some extent.
This sad forecast rests on several factors. First of all, the world population is rapidly growing, creating more blessings of civilization that, in turn, require enormous amounts of water. The current global climate change is turning fertile lands into deserts and making agricultural production increasingly water-intensive.
In the most recent estimate, every man on Earth needs 1,000 cubic meters of water on the average for drinking, washing, and producing food. Provision with water depends on the region, since the distribution of water resources is very uneven.
It is especially difficult to provide enough water in the arid regions of the Third World, which has a highly dense and rapidly growing population.
