Which of the following actions contribute to environmental health?

• A. Vaccination programs
• B. Regular exercise
• C. Access to healthcare
• D. Clean air/water, clean food, safe surroundings

Answer: (D)

Environmental health centers on how the surrounding environment influences health and how we reduce hazards in air, water, food, and living spaces. The best choice points to actions that address these environmental conditions directly: clean air and water, safe food, and safe surroundings. When the environment is free from pollutants, contaminants, and hazards, people experience fewer illnesses and injuries tied to those exposures.

Vaccination programs, while crucial for preventing infectious diseases, operate by boosting individual or population immunity rather than altering environmental risks. Regular exercise improves personal health but doesn’t change environmental factors. Access to healthcare ensures people can obtain medical care, yet it doesn’t inherently modify the environment or reduce environmental hazards.
