The document is a letter written in 2070 describing a dire future with severe water shortages. The letter details how pollution and overuse of water resources has led to widespread environmental destruction and health problems. Trees and vegetation have disappeared, the climate is desert-like, and people struggle to find even small amounts of water to drink. The writer regrets that past generations like their own did not take warnings about protecting the environment seriously, and feels responsible for the difficulties faced by current and future generations.
