A drop of water can save your life

Abstract

Every year, people around the world celebrate World Water Day on 22 March. This year the theme is ‘Water and Sustainable Development’. Water is at the core of sustainable development. This means that we need to protect our water resources and manage them so that we can grow our cities and towns while making sure that we all have enough water to go around. But it is not just our factories and farmers that need water. Water is also essential to human health. The human body can last weeks without food, but only days without water. This means that water is essential to our survival.
