Which action best demonstrates environmental health focus?

• A. Keeping air clean, water safe, food safe, and surroundings safe
• B. Drinking water
• C. Vaccination
• D. Regular exercise

Answer: (A)

Environmental health aims to prevent illness by managing the surroundings that influence health, including air, water, food, and living conditions. Keeping air clean, water safe, food safe, and surroundings safe directly targets these environmental determinants, making it the strongest demonstration of an environmental health focus.

Drinking water is essential and relates to environmental health, but it only covers one aspect rather than the whole environment. Vaccination protects individuals against specific diseases but is more about personal immune protection than environmental factors. Regular exercise improves individual health but does not address environmental conditions.
