With dissolved sulfuric acid and nitric acid that are formed in the air from sulfur dioxide and nitric oxide generated by power plants, smelters, other industrial plants, factories and cars, acid rain can seriously injure plants (Miller, 2001). A decrease in applied water can cause production and yield to decrease. Most of the absorbed water in plants is lost through transpiration and only about 1 percent or less is used in the various biochemical processes (Devlin, 1975;  Mader, 1993). Water is also used in agriculture, such as to keep livestock clean and healthy, and to grow crops and produce. Water and carbon dioxide are the two key components of plant photosynthesis, which is how plants make their food. Likewise, under similar conditions,  growth cracks occur as exemplified by bursting heads of cabbage and cracked fruits of tomato and roots of carrot and sweet potato.
