Water is one of the world’s most precious resources – but as the planet’s climate changes and the population rises, up to 5.7 billion people could be living in areas where water is scarce for at least one month a year by 2050. That’s why companies and individuals are exploring ways of saving this life-giving liquid.
Humans need water to survive – and not just fresh water for drinking. We rely on different kinds of water for a huge range of services and products, from sanitation and healthcare through to growing food crops and making clothes. In our daily lives, we use water for taking showers and washing laundry, and it’s also a key ingredient in a wide variety of the products that we buy. But even though 71 percent of the Earth’s surface is covered by water, less than 1 percent is fresh water that is suitable for human consumption. Today, around 1 in 3 people live without safe drinking water, and global water demand is expected to increase by more than 50 percent by 2040.
