Approximately 5,000 juvenile individuals lose their lives on a daily basis due to diseases that are entirely preventable, such as cholera and dysentery. These illnesses proliferate when individuals consume or prepare food using contaminated water. The absence of clean water for personal hygiene also facilitates the transmission of entirely preventable conditions like trachoma, which has resulted in the loss of sight for an estimated six million individuals.
The scarcity of water resources also ensnares numerous households with limited financial means in a perpetual loop of economic hardship and suboptimal educational opportunities, with the most impoverished being disproportionately affected by the lack of access to water. Those who dedicate a significant portion of their daily routine to dealing with health issues, tending to ailing children, or traversing an average distance of 3.75 miles to gather water, are deprived of the educational and economic opportunities necessary to elevate their living conditions.
Agriculture is often referred to as the primary consumer of clean water globally, accounting for approximately 70 percent of its usage, while industrial applications require an additional 22 percent. Water bodies do not recognize political boundaries, and nations do not consistently collaborate in the equitable distribution of these shared resources, making water a frequent catalyst for international disputes.
The ongoing demand for water is steadily increasing, depleting sources from vast rivers to subterranean aquifers. As Postel remarked, "We are progressively incurring a greater debt in terms of our groundwater exploitation, which has profound implications for the security of our global water supply. The pace at which we are extracting groundwater has doubled since the year 1960."
Some of the Earth's groundwater is classified as fossil water, a resource that originated during a time when the planet's climate was vastly different from what it is today. Presently, such water is as finite as petroleum. "However, we are extracting a significant portion of these resources at an unprecedented rate," Postel elucidated. "The escalating demand for water by humanity also poses a significant challenge concerning water and our ecosystems. This not only incurs a cost to the natural environment but also has long-term financial implications for future generations, including our offspring and grandchildren."
