Water
is essential for all dimensions of
life. Over the past few decades, use of water has increased, and in
many places
water availability is falling to crisis levels. More than eighty
countries, with forty
percent of the world’s population, are already facing water shortages,
while by year
2020 the world’s population will double. The costs of water
infrastructure have risen
dramatically. The quality of water in rivers and underground has
deteriorated, due to
pollution by waste and contaminants from cities, industry and
agriculture. Ecosystems are
being destroyed, sometimes permanently. Over one billion people lack
safe water, and three
billion lack sanitation; eighty per cent of infectious diseases are
waterborne, killing
millions of children each year.
