Safety and security are basic needs of humans.
|
The
potential for accidents and the existence of hazards imposes the need for
injury prevention. Safe living involves the development and use of safety precautions and the recognition of risk in personal decisions. Injury prevention has personal and social dimensions. |
Natural
environments may contain substances (for example, radon and lead) that are
harmful to human beings. Maintaining environmental health involves establishing or monitoring quality standards, related to use of soil, water, and air.. |
| Individuals
have some responsibility for their own health. Some diseases are communicable, such as colds, can be prevented with hygiene. The body’s defense mechanisms can prevent or overcome illness. Nutrition is essential to health. |
Good
nutrition include eating a variety of foods, eating less sugar, and eating
less fat. Regular exercise in important to the maintenance and improvement of health. The benefits of physical fitness include maintaining healthy weight, having energy and strength for routine activities, good muscle tone, bone strength, strong heart/lung systems, and improved mental health. Personal exercise, especially developing cardiovascular endurance, is the foundation of physical fitness. |
Food provides energy and nutrients for growth and development. Nutrition requirements vary with body weight, age, sex, activity, and body functioning. |
| What people eat or use affects their well being. | Different
substances can damage the body and how it functions. Such substances include
tobacco, alcohol, over the counter medicines, and illicit drugs. Prescription drugs, can be beneficial, but that any substance can be harmful if used inappropriately. The use of tobacco increases the risk of illness. |
Alcohol
and other drugs are often abused substances. Such drugs change how the body functions and can lead to addiction. |
| Sex drive is a natural human function that requires understanding. Sex is also a prominent means of transmitting diseases. The diseases can be prevented through a variety of precautions. | ||
| Internal
and external processes of the earth system cause natural hazards, events
that change or destroy human and wildlife habitats, damage property, and
harm or kill humans. Natural hazards include earthquakes, landslides, wildfires, volcanic eruptions, floods, storms, and even possible impacts of asteroids. |
Human activities also can induce hazards through resources acquisition, urban growth, land-use decisions, and waste disposal. Such activities can accelerate many natural changes. | Natural hazards can present personal and societal challenges because miss identifying the change or incorrectly estimating the rate and scale of change may result in either too little attention and significant human costs or too much cost for unneeded preventative measures. |
| Life involves risks. | Risk analysis considers the type of hazard and estimates the number of people that might be exposed and the number likely to suffer consequences. The results are used to determine the options for reducing or eliminating risks. | There
are risks associated with natural hazards (fires, floods, tornadoes, hurricanes,
earthquakes, and volcanic eruptions). with chemical hazards (pollutants
in air, water, soil, and food), with biological hazards (pollen, viruses,
bacterial, and parasite), social hazards (occupational safety and transportation).
and with personal hazards (smoking, dieting, and drinking). Individuals can use a systematic approach to thinking critically about risks and benefits. Examples include applying probability estimates to risks and comparing them to estimated personal and social benefits. Important personal and social decisions are made based on perceptions of benefits and risks. |
