The four categories of human environmental hazards are Cultural Hazards, Biological Hazards, Physical Hazards, and Chemical hazards. Cultural Hazards result from where we live, our socioeconomic status, occupation, or behavioral choices. For example, we may have a nice home built in the middle of a field of big power lines. Somewhere down the line being around the power lines for a long period of time may put you at risk of developing some sort of cancer. Another example is you may choose to smoke and you already know that it is a hazard to your health and what the consequences may be. One more example of a cultural hazard is using drugs.
Biological Hazards result from ecological interaction among organisms. They consist of bacterial or virus infection or other pathogens. Biological hazards are communicable diseases or transmissible diseases such as malaria, cholera, tuberculosis, and influenza. It is possible to get rid of these hazards but there are ways to prevent the wide spread devastation they can cause. Biological hazards spread every day from person to person. A basic interaction with another person can cause you to fall victim of a biological hazard. There are ways to prevent biological hazards such as vaccinations and cleanliness.
Physical hazards are also known as natural disasters. Some examples of physical hazards are earthquakes, volcano eruptions, floods, droughts, and hurricanes. Another example of a physical hazard is ultra violet rays from the sunlight. All of the physical hazards can cause devastation to the world as we know it. These natural disasters can strike undetected and thousands of humans, animals, and plant life can be affected by them. Volcano eruptions can wipe everything out in its path. Hurricanes can kill people and destroy property.
Chemical Hazards are the worst hazards in my opinion. They are the worst because they are the most common. Anyone can get their hands on chemicals. Chemical hazards are...
