The exposure to hazards in our environment brings us to the risk of injury, disease, and death to people in one way or another (Boorse & Wright, 2011, 2008, 2005). Such things are called environmental hazards. There are four categories of human environmental hazards. These hazards are cultural, biological, physical, and chemical (Boorse & Wright, 2011, 2008, 2005).
Cultural hazards are hazards that are brought upon ourselves by the things we expose ourselves to. We engage in risky behavior all the time; therefore subjecting ourselves to these hazards. Some of us consume alcohol, smoke cigarettes, are obese, have risky occupations (such as a police officer, doctor/nurse, or a correctional officer), some of us use drugs, and some of us may engage in having unprotected sex; which could result in a sexually transmitted disease otherwise known as an STD. Let’s face it even though we know these different things are hazards we still engage in them because they bring us pleasure or we derive other benefits from them. 40% of all deaths in the United States can be traced to cultural hazards. In most cases, deaths from cultural hazards are preventable (if people refrain from their risky behavior) (Boorse & Wright, 2011, 2008, 2005).
Biological hazards account for one-fourth of global deaths due to infectious and parasitic diseases. Sources of biological hazards include bacteria, virus, insects, plants, birds, animals, and humans. These sources can cause a variety of health affects ranging from skin irritations and allergies to infections, cancer and so on. The leading cause of death in this category are the acute respiratory infections (for example: pneumonia, diphtheria, influenza, and streptococcal infections), both bacterial and viral. A biological hazard, also known as a biohazard, is...
