The environment is everything around us - the air we breathe, the water we drink and use, and the food we consume. It's also the chemicals, radiation, microbes, and physical forces with which we come into contact. Our interactions with the environment are complex and are not always healthy. Health conditions such as asthma, foodborne illnesses, lead exposure, radiation exposure, litter and allergies are all impacted by the environment.
