Huff Post Green, Joan Michelson, May 2014 — We cannot exist without water. Water is literally “a vital nutrient to the life of every cell,” according to the U.S. Geological Survey (USGS) website. The body weight of some organisms is as much as 90 percent water. The human body is up to 60 percent water, “the brain and heart are composed of 73 percent water,” while our “lungs are about 83 percent water,” our skin is 64 percent, our muscles and kidneys are 79 percent, and our bones are about 31 percent water. “Each day humans must consume a certain amount of water to survive,” approximately 2-3 liters per day, some of which is consumed through food.
Water scarcity is very scary (is there a connection between the word “scarcity” and “scary”?) for the average person to even think about. Yet, about 38 percent of the U.S. is suffering drought conditions, some of which have continued for nearly 4 years and imperiled the food supply, creating a new “dust bowl.” Many parts of the globe, especially impoverished areas, suffer tremendous water shortages and as climate change continues that will only worsen.
