You are like Water on Earth moving continuously through the water cycle of evaporation and transpiration (evapotranspiration), condensation, precipitation, and then run off, usually reaching the sea to my heart. Evaporation from one and transpiration to another contribute to the precipitation over land(my life). Like Water you are used in the production of a good or service is known as the virtual you.
Safely drinking you is essential to me and other lifeforms even though it provides no calories or organic nutrients. Access to safe drinking you has improved over the last years in almost every part of my world, even though approximately one billion people still lack access to you and over 2.5 billion have access to adequate sanitation.
