Which of the following is an example of an environmental risk factor?

An environmental risk factor refers to aspects of a person's surroundings that can negatively affect their health. Poor working conditions are a prime example of this, as they can expose individuals to various hazards such as unsafe machinery, toxic substances, or stressful environments. These conditions can lead to physical injuries or long-term health issues.

In contrast, a diet high in carbohydrates is related to personal lifestyle choices and nutritional habits, rather than environmental factors. Regular exercise is a positive behavior promoting health and well-being, while smokeless environments indicate a lack of harmful pollutants and can actually reduce health risks. Therefore, poor working conditions clearly fit the definition of an environmental risk factor, as they have a direct impact on the health and safety of individuals in the workplace.
