low- pressure spray irrigation that sprays water downward toward plants and by using drip irrigation systems that target individual plants and introduce water directly onto the soil. Both methods reduce the amount of water lost to evaporation and surface runoff. In addition, choosing crops to match the land and climate in which they are being farmed can save huge amounts of water. Presently, crops that require a great deal of water, such as cotton, rice, and alfalfa, are often planted in hot and arid areas where irrigation is government subsidized. The true cost of water, therefore, is not taken into account as part of the costs of growing the crop. Eliminating subsidies and growing crops in climates that provide adequate rainfall could greatly reduce water use in many parts of the world. In addition, the selective breeding and/or genetic modification of crops is resulting in some varieties that require less water. -Discuss the environmental, quality, and economic issues associated with the manufacture and consumption of bottled water.
