Question

question 1

______ and exposure to uv light, lead, pesticides, and asbestos are examples of environmental risk factors that can lead to disease.

lack of access to clean water

smoking and alcohol use

lack of physical exercise

an unhealthy diet

Explanation:

Environmental risk factors are external elements in the surroundings that can increase the likelihood of disease. UV light, lead, pesticides, and asbestos are all external environmental agents. Lack of access to clean water is also an environmental factor as it pertains to the external environment (availability of a basic environmental resource - clean water). Smoking and alcohol use are lifestyle choices (more related to personal behavior rather than the external environment). Lack of physical exercise is a personal activity - related behavior. An unhealthy diet is a personal dietary choice. So, among the options, lack of access to clean water fits as an environmental risk factor similar to the other examples (UV light, lead etc.) which are all environmental in nature.

Answer:

lack of access to clean water
