In the year 2070, water has become scarce due to climate change and war. The narrator recalls that as a child in 2015, water shortages were just beginning but not seen as a major problem yet. The narrator's parents told them the issue would fix itself, but it grew severe instead. After World War 3 devastated the nation, the little remaining water was lost. Now, water is not sold in stores and must be found elsewhere, often not being clean. A water purifier is a valuable item, as people sometimes must walk miles to find any water at all and clean water is almost impossible to locate.
