Toxic PCs Essay Example for Free

Toxic PCs Essay Computer hardware can contain a variety of toxic and hazardous materials. Today I’m going to talk about these kinds of materials and why they are toxic to our environment. I’m going to discuss the locations of disposed electronics and how it is done. When consumers donate old televisions and monitors to recyclers those companies should dispose of them in a manner that doesn’t harm the environment. Stockpiling monitors is hazardous to the environment. This is because the glass could easily break and the lead which is a neurotoxin material enters the soil and ground water. One of the major environmental impacts of dumping computers into landfills is due to the fact that the solder used in the components of the circuit boards is comprised of a tin-lead alloy and over time the lead can leach from the solder. Usually the lead, which is a toxic substance, finds its way into the drinking water (Warren, Scott) There are different type of companies that recycle electronics in different communities and some of them are nonprofit companies you just donate your computer to them for example there is this company in Michigan it is called Responsible Electronics Recycling they recycle computer the right way breaking computers into small particles and removing all the toxic material from getting into our environment. The role of disposing electronic has a great advantage because when monitors get recycled the right way they can be reused again for goods. The Responsible Electronic Recycling Company says: Our mission is to inspire our community to live and work in a sustainable manner. This mission is accomplished by providing environmentally responsible electronics recycling and green job training for at-risk youth and challenged adults. 100% of proceeds generated go toward community service programs that focus on education and environmental initiatives (Responsible Electronic Recycling). And this is how recycling is done to these electronics. I think the technology will have an influence on our health and our environment because of all the toxic material that is used in the advanced electronics and if our air is polluted then it is going to have an effect on our health. The health effects of toxic substances and hazardous wastes are not yet fully understood. Research to better understand how these exposures may impact health is ongoing. Meanwhile, efforts to reduce exposures continue. Reducing exposure to toxic substances and hazardous wastes is fundamental to environmental health  (Geneva, Switzerland). I think if we take care of our environment meaning by not polluting the air and soil we will be able to reduce the risk of having any health problems but if we do not do so this polluted environment will lead us to have issues regarding our economy later on in the future. Therefore we need to work on educating each other and take action. Finally after looking at all the information above I think now we see why we need to think carefully when we are getting rid of an old computer or any electronic. We need to make sure that if our computer been donated to a manufacture for disposal it is going to be disposed properly and everyone should take this into consideration and practice the right way to recycle electronics.

Scoliosis :: Health, Informative, Medicine

Scoliosis   Ã‚  Ã‚  Ã‚  Ã‚  Everyone's spine has curves. These curves produce the normal rounding of the shoulder and the sway of the lower back. A spine with scoliosis has abnormal curves with a rotational deformity. This means that the spine turns on its axis like a corkscrew.   Ã‚  Ã‚  Ã‚  Ã‚  Scoliosis is a curvature of the spine which may have its onset in infancy but is most frequently discovered in adolescence. It is more common in females by a 2:1 ratio. However, when curves in excess of 30 degrees are evaluated, females are more frequently affected by a ration of approximately10:1. The cause of the most common form of scoliosis; idiopathic scoliosis. is unknown, but there have been hereditary factors discovered that are present.   Ã‚  Ã‚  Ã‚  Ã‚  Scoliosis causes shoulder, trunk and waistline â€Å"asymmetry†. In mild forms, the condition may be barely noticed; however, in severe forms there is significant disfigurement, back pain and postural fatigue, and it may be associated with heart failure. Fortunately the majority of scoliosis cases need only close follow-up to watch for worsening of the curve. Some cases require more aggressive treatment which could include surgery.   Ã‚  Ã‚  Ã‚  Ã‚  The non-operative treatment of scoliosis involves observing the deformity with examinations and repeated x-rays. Under certain circumstances, when spinal growth remains, a brace may be used in combination with follow-up x- rays. Physical therapy exercises have not been shown to be effective treatment for scoliosis.   Ã‚  Ã‚  Ã‚  Ã‚  The most common surgical treatment for scoliosis is a spine fusion using special stainless steel rods, hooks, and a bone graft. The rods are attached to the spine with hooks and the curved portion of the spine is carefully

Hmong Culture Essay

The Hmong people is a minority ethnic group that resides in several countries worldwide. Hmong people is originally from Laos, a Asian country. The Hmong people usually resides on the mountains and their life has revolved around their inherent lifestyle and beliefs. War and migration along with the long history of being an oppressed ethnic group developed Hmong way of life. However, the Hmong culture is so persistent despite the forces of change around. The typical day of a Hmong family will start usually at four in the morning or when the rooster crows. The oldest daughter or daughter-in-law prepare the breakfast for the family, feed the animals and do the household chores. The husband occasionally helps his wife in feeding the animals and grinding the corn. After breakfast, the working members of the family will head out to the field and leave their children at the care of their paternal grandparents. Children who are six years old and older accompany their parents in the fields and do what they can do to help. The working members of the family usually go home before sunset and they gather firewood, plants and herbs along the way to add to their supplies at home. Hmong always have dinner together as a family and share stories of the day. A traditional Hmong family is patriarchal and the son tends to not to leave the house of his parents to work for them and to have someone to take care of his children while he and his wife is out tending the fields. Hmong are group oriented and they tend to depend on each other for survival. Thus, the interest of the groups must come first before the vested interest of the individual. â€Å"Family is the basic social unit in the conventional Hmong society. It is the unit of production, consumption, socialization, social control and mutual assistance. The common Hmong family is composed of an extended family that is made up of many generations. Hmong people are animists, they acquire strong belief in spirits and the supernatural world that cannot be explained by exact science. However, most of the Hmong people in United States become Christians but the traditional spiritual beliefs remain in them as part of their cultural practices. Still, practices and ceremonies are altered as Hmong adapt on the American society. Hmong people deeply believes that the souls live in a supernatural world. These spirits decide when a person dies. Also, they believe that these spirits or souls are Hmong people waiting to be born or to be reborn and reenter the earth. Furthermore, many Hmong believe that every person has a personal spirit who takes care of him, just like a guardian angel. Contacts with these spirits is usually done by the shaman or the religious and medical leader of the group. The shaman is the Hmong resident physician and their role is mainly to heal sick people and to prevent further spreading of illness or disease through interaction of the spirits. The shaman is one of the most important people in the Hmong village. He is the one who provides hope in times of crises. The shaman also guides the people in difficult situations. In addition to the shaman, Hmong people also practice traditional alternative medicine through the use of herbs and plants which grow in the wild in the mountains. From these plants, they produce ointments and salves to help them with their injuries and to make the sick feel better. However, Hmong people in the United States adapted to the American modernized medicine. But still, Hmong people continue to visit a shaman once in a while as part of their rich and undying custom and tradition.

My Trip On The Car - 1063 Words

Fingers laced ten-and-two around the steering wheel, a familiar melody made its way through the speakers. As I drove down the familiar road my mind wandered, yet my tires moved steady on the asphalt. Moments passed, and a cool breeze through the open windows brought me back to reality. However, the reality was not what I was prepared for. My foot felt like lead hitting the brakes, and so did my heart hitting my stomach. My Ford Focus was no match for the white SUV that pulled out in front of me. The man in the vehicle opposite to me seemed paralyzed by fear, because he looked at me but did not move. Almost involuntarily, my hands jerked the steering wheel to the left, causing me to miss his vehicle by a foot. The sound of metal against metal sent a chill through my spine, and the road sign I hit flew across the road. My engine stopped, along with my train of thought, and my whole world felt as if I were trapped in a snow globe that had just been shaken. The overwhelming scent of burn ing rubber, and the churning under my hood brought me back to the present. Although my car suffered, I knew my split-second decision saved not only my life, but the stranger that couldn’t seem to wait to turn. My brain could barely process the yelling that filled the air.
