Downfall: Precipitation or Extinction? Water stress, an insufficient water supply on a worldwide scale, is “considered by many scientists as one of the biggest challenges facing humanity and struggling ecosystems in a world increasingly affected by climate change.” Even though water conveys the impression of being an interminable provision, only 3% of the Earth’s water is fresh. The preponderance of areas currently suffer from inutile freshwater. For instance, 68% of fresh water is frozen in the form of of icecaps and glaciers. Roughly 30% is groundwater, and the remainder of freshwater is .3%, located on surfaces of lakes, rivers, and swamps. Moreover, avaricious humans are not the only organisms that depend upon freshwater for survival. This leaves less than 1% of water to share with over millions of species. On the Principle of Population, by Thomas Malthus, mentions that the sustainable resource correlation to exponential population growth implies “a strong and constantly operating check on population from the difficulty of subsistence.” The Renewable Groundwater Stress ratio can be measured by the water consumption amount to the volume of available water. Gravity Recovery and Climate Experiment (GRACE), partnering with NASA, estimates the remaining freshwater, duration of depletion, and efficiency of preventive means to impede further water drainage. There are four categories used to determine the water levels: Overstressed, Variable Stressed, Human-Dominated Stress,
