By the year 2025 it is predicted that, “1800 million people will be living in countries or regions with absolute water scarcity and that two-thirds of the world population could be under stress conditions caused by water scarcity”(IFAD). This data suggests an imminent and terrifying reality, earth is slowly running out of drinkable fresh water. This reality will most likely cause wars, starvation, and death for water is vital for human life with 20 to 50 liters needed daily to sustain basic human functions (IFAD). Unless we find a solution to this international human crisis, life as we know it will not be sustainable. Fortunately, scientists across the globe have made its their mission to prevent this crisis from occurring through…show more content…
Soil salinity problems also develop and are “known to increase the incidence of water-borne diseases like malaria, filariasis, yellow fever, dengue, and schistosomiasis (Bilharzia) in many areas” (Wikipedia). Not only does rising water increase the risk of disease it can also cause the soil to dissolve nutrients which causes high levels of these nutrients in ground water. Nitrates are an example of a nutrient that is dissolved into water from high water tables, and it is incredibly toxic to infant under 6 months causing death in many regions (Wikipedia).
Current irrigation systems are not only dangerous to humans they are incredibly wasteful. With most the worlds water being used for these methods these wasteful processes are slowly causing the loss of fresh drinking water for many parts of the world. California is an example of how wasteful irrigation practices have destroyed this region. The former Arizona governor and U.S. Secretary of the Interior said “There is enough water in the West‚ [but] there are all kinds of agriculture efficiencies that have not been put into place” (propublica). The current systems are wasteful for several reasons, the most wasteful being evaporation and over watering. Many of the current systems do not prevent the water in the fields from evaporating and overwatering which wastes thousands of gallons of usable
