write one page paper defining the four categories of human environmental hazards, including giving examples of each.
Weegy: Human Environmental Hazards The environment is made up of human life or also known as the physical, chemical, biological, and the cultural of the human race. There is always something that makes people sick or cause death at all different ages. [ This is called a hazard or even a danger. A hazard is anything that can cause harm, disease, or death to humans, damage to personal or public property or the weakening or destruction of environmental elements. Hazards are all around a person’s everyday life. For example in their home, the air they breathe, the water and food they digest, and their workplace. The four main categories of human environmental hazards are always a factor of life. Physical hazards can also be classified as natural disasters. This includes earthquakes, volcano eruptions, floods, hurricanes and droughts. These physical hazards can cause devastation to the world. Anyone of these natural disasters can cause death and destroy property. Physical hazards have no time line of when, where, or why they happen. The average death toll from natural disasters range from 43,000 to 200,000 each year in the United States. The majority of these deaths are in poor communities. Cultural hazards are from people’s behavior and lifestyle choices. Cultural hazards result from eating too much, the use of addictive and harmful drugs, sunbathing, not exercising enough or by choosing hazardous occupations. Around 40% of all deaths in the U.S. can be traced to cultural hazards. Crime can also be considered as a cultural hazard because it is an action that a person takes a roll in. A biological hazard is another category of human environmental hazards. Biological hazards are bacterial or virus infection or even other pathogens. This hazard is a communicable disease or a transmissible disease. They are referred to as epidemics like the black plague, malaria, tuberculosis, and influenza. Most of these hazards can be prevented. One-fourth of deaths in the world are due ... (More)

Define "global warming." Describe briefly the theory behind man-caused global warming. Include a list of some of the gases that are believed to contribute to global warming. What are the causes of increased greenhouse gases in the atmosphere? What country do you think is the largest contributor to global warming? What types of industries emit the most greenhouse gases? What is the evidence that global warming is a real process caused by humans and occurring right now? What is the evidence ...
Weegy: What is global warming? While some would call global warming a theory, others would call it a proven set of facts. Opinions differ vehemently. [ Let us consider global warming to be both a premise that the environment of the world as we know it is slowly, but very surely increasing in overall air and water temperature, and a promise that if whatever is causing this trend is not interrupted or challenged life on earth will dynamically be affected. The prevailing counter opinion is that all that is presently perceived to be global warming is simply the result of a normal climactic swing in the direction of increased temperature. Many proponents of this global warming ideology have definitive social and financial interests in these claims. Global warming and climate change are aspects of our environment that cannot be easily or quickly discounted. Many factions still strongly feel that the changes our Earth is seeing are the result of a natural climatic adjustment. Regardless of one’s perspective the effects of global warming are a quantifiable set of environmental results that are in addition to any normal changes in climate. That is why the effects of global warming have catastrophic potential. Global warming may well be the straw that breaks the camel’s back. It could turn out to be the difference between a category three hurricane and a category four. Global warming as caused by greenhouse gas emissions can lead us to a definite imbalance of nature. The premise of global warming as an issue of debate is that industrial growth coupled with non-structured methods we as humans use to sustain ourselves has created a situation where our planet is getting progressively hotter. We have seemingly negatively effected our environment by a cycle of harmful processes that now seem to be feeding upon themselves to exponentially increase the damage to our ecosystem. Causes of Global Warming Let us start our examination of Global warming with a study of its causes. ... (More)
