Sanitation is critical for several reasons: 1. Prevents Disease Transmission: Poor sanitation can lead to the spread of pathogens that cause diseases such as cholera, dysentery, and typhoid. 2. Improves Health Outcomes: Access to clean water and proper waste management reduces the incidence of waterborne and vector-borne diseases. 3. Enhances Quality of Life: Proper sanitation practices improve overall quality of life and dignity, particularly in low-income communities.
