Although radiation appears to be benefiting the general population, the public must understand the breakdown of nuclear power and the dangers of radiation. Radiation consists of multiple different types of subatomic particles, such as neutrons, electrons, and alpha particles. These particles move at extremely high rates, something like 100,000 miles per second, and can easily penetrate deep inside the human body. This penetration actually damages some of the biological cells of which our body is composed of. Such damage can cause a fatal cancer to develop.
However, that market is high competitive and almost commodity-like. Company A would need to consider reducing its labor force or even moving its operation to low cost-region in order to be competitive in the iPod/iPhone headphone market. Another new customer group is the people who use noise-cancellation headphones. There are limited players in this market. Also, the quality of noise cancellation headphones vary a lot and the customers are willing to pay higher price for good product.
New inventions changed the very way people resided. One of the most important inventions of all time was the light bulb, founded by Thomas Alva Edison. Edison developed and distributed a system for electricity, eliminating further need of fire-hazardous oil lamps. Electricity was used to improve transportation, increase production and revolutionize business (Danzer 248). Faster production also contributed greatly to the progressions made by the industrial era.
Antibiotics only treat infections caused by bacteria and not illnesses caused by viruses. The doctor finds prescribing antibiotics to be the easiest way to take care of a patient instead of treating the infection or illness. Many people believe that antibiotics are the cure for every infection or disease; however that couldn’t be farther from the truth. We should encourage the doctors to prescribe medications to treat illness and only resort to antibiotics when other prescriptions fail. Improper use of antibiotics is the primary cause of drug-resistant bacteria.
[M1] Assess the biomedical and socio-medical models of health The biomedical model approach to health is used primarily in the western world and industrialised societies. It originated after the industrial revolution of the mid-nineteenth century. This model is largely based on the ideology that health is defined as the absence of the disease and that only; the model is adamant that the involvement of health care professionals is necessary in every incident of illness. The biomedical model became popular because of the use of scientific methods; its main purpose is to cure disease; the treatment and care of people is cheaper; expert knowledge is used to achieve the results; and public health has improved. It has one focus; the actual
Coal, natural gas, and oil are burned for energy in many ways such as cars and power plants. Forest burning for deforestation also causes C02 emissions. C02 emissions are harmful to the planet and cause the planet to heat up. Global warming causes worse weather conditions in the world amongst other issues. With so many issues that can arise with a hotter Earth, I believe this to be a major issue that needs to be addressed.
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
The Efficiency of Cars Nikeisha S. Sandy SCI207: Dependence of Man on the Environment (ABL1146J) Instructor: Walter Lambert December 12, 2011 The efficiency of cars is a major issue. There are several reasons why cars should be more efficient, however, there are many reasons why they should not. The efficiency of a car can affect both the economy and the atmosphere. While cars should not be more efficient, cars should be more efficient because the cost to the consumer may decrease, more efficient cars can save money on taxes, and cars are a necessity. At one point, the idea of using a car that was electric powered may have seemed outrageous.
Presently, pessimism prevails. Many feel that the technology solutions created by an industrial economy to improve human well being has led to insurmountable environmental degradation. As coal and oil technologies reach an inevitable peak in production, unanticipated and uncontrollable consequences of their abuse are becoming more pronounced in natural systems not long after their introduction as the economic life vein. Even so, pushes for new technological development have emerged to counteract the damage already done and optimism remains to reverse their effects on the environment through innovation. As explained by Paul Gray, therein lies a technological paradox, that environmental deterioration is brought about by the industrial economy, but the progression of this industrial economy is and will be the road to successful environmental stewardship (Ausubel, 1989).
These sources of pollution don’t simply have a negative impact on the world, but they can have a measurable effect on the health of human beings. Different types of pollution 1. Air Pollution Air pollution is defined as any contamination of the atmosphere that disturb the natural composition and chemistry of the air. This can be in the form of dust or excessive gases like carbon dioxide or other vapors. Air pollution comes from a wide variety of sources * Vehicle or manufacturing exhaust * Forest fires, volcanic eruption, dry soil erosion * Building construction or demolition Many scientists believe that global warming is also related to increased air pollution.
