Solutions to Diminishing Ground Water
Water is a defining feature of the earth and absolutely essential for sustaining life. In total, 70 percent of the earth’s surface is covered with water. However, 97.5 percent of that is salt water, which makes it undrinkable for humans and unusable for irrigation. Fresh water accounts for the other 2.5 percent, but about two thirds of that is locked up in glaciers and thick ice sheets on the north and south poles.
