Why is fresh water important?

FOOD WE EAT

A huge amount of humanity?s available fresh water — 70% of it — is used for agriculture. What?s more, freshwater fish and other species are an important part of many people?s diets. The lesson is simple. Without water, we?d starve — and so would the fish.

ENERGY TO FUEL GROWTH

If you?re reading this on an electronic device, water made it possible. That?s because energy extraction and production requires the use of water. It?s the driver for hydropower, the cooling mechanism for power plants and the reason biofuels can grow. Water powers our lives.

WATER WE DRINK

The average person can go for three weeks without food, but only three days without water. Yet less than 1% of the fresh water on Earth is readily accessible for human use. We have to use what we have responsibly. And we must protect the natural places, like forests and wetlands that store, filter and supply clean water for everyone on the planet.
