<P>The World Health Organization defines environmental health as "those aspects of human health, including quality of life, that are determined by physical, chemical, biologic, social, and psychosocial factors in the environment." Anything that affects the environmental health of humans, plants, and animals in a negative way is an environmental hazard. Many people live on the edge of an environmental hazard. From the people who reside in Southern California where earthquakes are common to those who live near an abandoned copper mine that leaks dangerous arsenic into the groundwater, environmental dangers are part of our daily lives.
