Water is essential for life, health, industry, and agriculture. It is needed for basic survival, as dehydration can lead to death. Two to five liters per day are needed by the human body to stay hydrated. However, not all people have access to safe drinking water, which can spread diseases like malaria. Industries and agriculture also rely on water to operate and grow food. A lack of access to clean water impacts a country's ability to develop and feed its population.
