Model: Water is a unique component on our planet. We call it the “Blue Planet”. Unfortunately, 97 percent of the water on the Earth is salty and people can’t use it. The remaining 3 percent is fresh - meaning essentially “unsalty” in live organisms and in glaciers*. Fresh water is in springs and geyzers. Millions of people in the world are facing water shortages nowadays which could lead to a global crisis. What should we do to overcome such challenges?
