We Can Only Live a Few Days Without Water
- "...the hydrologic cycle starts with evaporation, primarily from the oceans, leaving the salt behind. As this moisture or water vapor rises into the atmosphere, it cools and the moisture condenses to form water droplets, or if cold enough, ice crystals, and then falls as precipitation, much of this over the ocean, but also over the continents. This natural distillation or desalting process gives us the supply of fresh water that the lives of the Earth's 7.1 billion people are totally dependent upon. We can live for weeks without food, but only a few days without water." - excerpt from article the Santa Cruz Sentinel by Gary Griggs.
