Why do we need to save water?

97.5% of the world’s water is locked in seas and oceans, too salty for human use. And most of the remaining 2.5% is in the ice caps.

So we humans depend on the tiny bit available as fresh water – an essential natural resource for life.

But we don't just use water for drinking. We wash in it, clean with it, and use it to produce everything from clothing to food. Crop production – including feed for livestock and biofuels – is putting a great strain on fresh water supplies.

Some Facts and Figures About Water Use

• Water covers 70.9 percent of the planet’s surface.
• 97 per cent of the that water is salt water.
• Around the world, 2.1 billion people still lack access to safe water.
• Water use is growing at twice the rate of population growth. Unless this trend is reversed and we come up with a way to share water fairly and sustainably throughout the planet, two-thirds of the global population will face water “stress” by 2025
• In the USA, the average water footprint per year per capita is as much as the water needed to fill an Olympic swimming pool, an average of 7,786 litres of water per person per day.
• In China, the average water footprint is 2,934 litres of water per person per day.
• In the Netherlands, 95 per cent of the water footprint of consumption lies somewhere else in the world (due to the amount of imported goods consumed), whereas in India and Paraguay only 3 per cent of the national water footprint of consumption is external.
• It requires around 1500 litres of water to produce 1 kilogram of wheat, and a huge 10 times more to produce the same amount of beef.
• The water footprint of a cup of coffee is around 140 litres, a cup of tea only around 34 litres.
