Water, or h2o
Once upon a time water was simply taken for granted. Essential to all life as we know it, and considered the most universal solvent. In it's pure form water is tasteless, colorless, and oderless. Water elements consist of 2 parts hydrogen and 1 part oxygen, abbreviated as H2O. Water is one of the most abundant substances on Earth and is the single most factor in supporting life as we know it. Without water there can be no life is the scientific way of seeing things, when it comes to this subject.
Water is found in all over the earth and even in our atmosphere. From the land we see it in oceans, rivers, lakes, and polar ice. In the atmosphere we see it in the clouds and through rain and snow. Water is constantly being filtered and is moving always. Through a cycle of evaporation into the atmosphere, and condensating back into droplets of precipitation, or rain, then falling back to earth, and finally "running off" back into the bodies of water all around us.
Many places today in our world are lacking this natural resource. Our populations have grown to an epic level where this resource is now more important than it ever was. Water that is consumable by humans is called "potable" water. The lack of this consumable water is become more evident as we move into the future. The availability of this resource has become a major economic and social concern around the world.
