Water is the driving force of all nature, Leonardo da Vinci claimed. Unfortunately for our planet, water supplies are now running dry at an alarming rate. The world’s population continues to increase but that rise in number has not been matched by adequate supplies of fresh water. Reports show that more than a billion individuals — one in seven people on the planet — now lack access to safe drinking water.

In Sao Paulo, a Brazilian city, drought got so bad that residents began drilling through basement floors and car parks to try to reach groundwater. Officials in this city warned that rationing（配给制）of water supplies was likely soon. Citizens in Sao Paulo might have access to water for only two days a week. In California, US, officials have shown that the state has entered its fourth year of drought. At the same time, its per capita（人均）water use has continued to rise.
