The environment is everything around us - the air we breathe, water we drink, the food we eat, the buildings and communities in which we live, learn, work and play. Certain elements in the environment we live or work in can sometimes be dangerous to our health or the health of our families. Examples of these environmental hazards are carbon monoxide, lead, and radon exposure. The health effects of these hazards vary, ranging from potential death in the case of carbon monoxide poisoning, to the developmental issues associated with childhood lead poisoning, or heat stress and stroke due to sun exposure.
