Give examples of the influence of environmental factors on your body.

Physical environmental factors that are important to health include hazardous substances such as air pollution or proximity to toxic objects (a focus of classical environmental epidemiology); access to a variety of health-related resources (eg, healthy or unhealthy food, recreational resources, health care); and community design and “built environment” (eg land-use mix, street communications, transportation systems). Air pollution is one of the biggest environmental problems affecting the human body as well. Water is a necessity to sustain life. Often, contaminated water becomes publicly available drinking water or water that is used to grow the food we eat.
