The document discusses water usage and conservation. It notes that only 0.007% of water on Earth is potable and that all living things require water. Billions of people lack access to clean water, resulting in millions of deaths each year from water-related diseases. While developed countries like Spain have expanded water infrastructure, conservation is still important given unequal water distribution and the costs of treatment. Small actions like fixing leaks, limiting shower time, and catching rain water can significantly reduce individual water usage.
