The Scarcity of Water on a Global Scale

"For many of us, clean water is so plentiful and readily available that we rarely, if ever, pause to consider what life would be like without it." -- Marcus Samuelsson --

About seventy percent of the earth is covered by water, yet roughly only one percent of that can be used for drinking (Sustainable World Coalition, 2014). Globally, water is often limited in both quality and quantity. It is even being considered the oil of the 21st century (Sustainable World Coalition, 2014). With populations increasing and industries growing, how will we be able to keep up with the growing demand for water? It is currently

Water pollution is a result of many different practices including fertilizer and pesticide use, discharge from farmlands, sediment runoff from construction sites, and various industrial practices. Many human activities both intentionally and unintentionally add chemicals and pollutants into both surface waters and underground aquifers. It is estimated that by 2050, global population will be around 9.6 billion people with about 523 million people in Africa lacking clean water resources (Sustainable World Coalition, 2014). According to the Washington Post, one flush of the toilet in the West uses more water than most Africans have to do an entire day’s work including cooking, cleaning, and drinking (Eliasson & Blumenthal, 2005). Rapid population growth, economic development, and industrialization have started to …show more content…
to tighten tap for farmers”, Bloomekatz mentioned that the government had reduced or even refused to supply water to some agriculture fields in 2009. In Central Valley, the government had refused to provide water for over 200 water districts. In the same time, the government had also reduced the municipal and the industrial allotment by half. Reduced water allotment forced farmers to grow fewer crops which eventually lead to the lay-off of current employees. This is when water shortage and irrigation are not only an ecological problem but also an economic problem.

Since most of our freshwater is used for irrigation, we are left with 2 options: find an alternative irrigation system or continue to misuse water. Restructuring our irrigation system will solve a large portion of our freshwater shortage problem. In 1998, seawater irrigation came into the picture. “Seawater irrigation is defined as growing salt-tolerant crops on land using water pumped from ocean for irrigation” (Gleen, Brown, and O’Leary 77). Seawater irrigation is promising because 97% of our planet is covered by saltwater. Compared to 1% of freshwater, we will have greater flexibility with
