This letter written in 2070 describes a dystopian future where water has become extremely scarce due to environmental destruction and climate change. The writer recalls how abundant water used to be but nobody paid attention to warnings. Now people are severely dehydrated, food is synthetic, industry has collapsed, and violence over water is common. The population suffers from disease and deformities. Life expectancy is only 35 years. The writer feels guilty for belonging to the generation that contributed to the environmental destruction and not heeding warnings, leaving future generations to pay the price.
