mankind abuse the water supply

modern man must think better about washing machines, dish washers, showering or bathing once or even twice a day, running the tap while preparing vegetables instead of just filling the bowl, run the tap to get hot water, ( this can be as much as two gallons) , in the pool that everyone has to have but never uses

Taken over nearly 40 years, photographs show the drying up of several bodies of water around the world - receding as mankind's demand for water grows.
Included in the shocking collection is the once mighty Aral Sea in Central Asia.

1999: More than 25 years on the sea has noticeably shrunk to less than half its size


2009: Satellite image taken last year shows a situation described as 'one of the planet's worst'

The drying is due to overuse of the lake's feeder rivers. In the 1960s the former Soviet Union diverted the Syr Darya and Amu Darya for the irrigation of cotton and paddy fields.
Now 50 years later the water is at a dismal 10 per cent of its level when the projects first began.
