The Life Cycle Assessment of Cell Phones
The mobile phone has become an essential product all around the world. A small handheld device with the ability call, send messages, and access the internet from almost anywhere in the world has become a necessity for many citizens of developed countries. Due to rapid technological advances, cellular phones become obsolete in a very short period of time. The average lifespan of a cell phone is only 18months in the US (LCA of Cell Phones). With over 233 million active cell phones in use in the US alone and 4 billion worldwide, it’s mindboggling to consider how many phones that have been created and discarded over the past few decades. 1. What environmental impacts are the most significant?
The energy usage costs accounts for over 30% of the total life cycle energy (LCA of Cell Phones). Depending on how the electricity is created (coal, natural gas, oil, etc.) lots of greenhouse gases and other pollutants are released into the air.
2. What lifestage(s) contribute the most to these impacts?
Energy usage occurs in the Product Consumption stage. The daily recharging of the battery is a huge energy obligation. 3. What are the strengths, flaws, and limitations of the analysis?
The analysis has a great amount of cell phone data within the US and gives great examples of LCA goals from companies like AT&T and Nokia. However there is almost no information about the LCA from the global perspective. Also there is no information about raw material acquisition and material manufacturing. 4. If you were a consultant tasked with improving this product’s environmental performance, what suggestions would you make?
Since 2/3rds of the energy used to recharge cell phone batteries is wasted, I believe this should be addressed (LCA of Cell Phones). After the battery of the cell phone is fully charged, energy is still…...

...A Call to Action: Regulate Use of Cell Phones on the Road When a cell phone goes off in a classroom or at a concert, we are irritated, but at least our lives are not endangered. When we are on the road, however, irresponsible cell phone users are more than irritating: They are putting our lives at risk. Many of us have witnessed drivers so distracted by dialing and chatting that they resemble drunk drivers, weaving between lanes, for example, or nearly running down pedestrians in crosswalks. A number of bills to regulate use of cell phones on the road have been introduced in state legislatures, and the time has come to push for their passage. Regulation is needed because drivers using phones are seriously impaired and because laws on negligent and reckless driving are not sufficient to punish offenders. No one can deny that cell phones have caused traffic deaths and injuries. Cell phones were implicated in three fatal accidents in November 1999 alone. Early in November, two-year-old Morgan Pena was killed by a driver distracted by his cell phone. Morgan’s mother, Patti Pena, reports that the driver “ran a stop sign at 45 mph, broadsided my vehicle and killed Morgan as she sat in her car seat.” A week later, corrections officer Shannon Smith, who was guarding prisoners by the side of the road, was killed by a woman distracted by a phone call (Besthoff).

...Cell Phone use While Driving In today society we as people use cell phone for communicate. They play an important role in communicating in our modern society. Even though a cell phone is the most convenient and fast way for getting in touch with people, they should not be used while operating a vehicle. Cell phone use while driving has dramatically increased over the past years in the U.S., and studies show that the risk of having an automobile accident or near accident significantly increases when a person is talking on their cell phone. Although, not everybody who uses their cell phone while driving has been or will be in an accident, but an alarming number of people who were involved in automobile accidents have been reported to have been using a cell phone while driving. Because of the increased number of traffic accidents caused by cell phones, it can be show that cell phone use should be banned while driving do to the risk of getting a ticket, people get distracted while they are texting and dialing a phone number and maybe hands free headset should be banned as well. Individual that uses their phone while driving is taking the risk of getting a ticket or even an accident. It’s easy to get distracted while driving, but don’t the reason you get distracted is because you are on your cell phone.

...attached to our phones. We would hardly communicate with each other, because we were so consumed in our phones. Being in a generation that has grown up on technology I get excited not frustrated with advances in technology. Older generations cannot seem to understand why “those young kids are attached to those things”. I honestly don’t know much different. I have always had a colored T.V a VCR, a CD player and a computer. Sure all of those have morphed into newer and better things, but I don’t know much else but technology. I think that even though I have always had technology around as I have gotten a little bit older I have become more aware of the damages it can do to our society. The video assigned to watch says it all. People can’t even go to the bathroom without using their phones! I loved the video, because although a couple of them were a little extreme, most of them I am guilty of! Because of my Iphone craze, I talked both my parents into upgrading there “bricks” into iphone. I have noticed that when we go out to dinner all three of us are on our phones until our food arrives. We do not talk as much as we used to because of the phones. It actually saddens me. As far as friends go, I have realized that I get really annoyed at one of my friends that is constantly on her phone. I don’t ever feel like she is listening to me and I often have to repeat myself because she indeed wasn’t listening. I have learned to appreciate the time that she puts her phone down for......

Cell Phones in It

...Cell Phones Technology in the country and around the world is expanding at an exponential pace. The last 10-15 years has seen a large increase for technology in everyday life. In the United States the biggest technological change is the use of cell phones in our lives for both personal and business use. Since the late 90’s cell phones have grown at a tremendous pace. Today there are very few people in the country that do not have one. Personal use of needing a cell phone has increased. Today we need to always have access to our phone for text messages, email or the old but common actual phone call. Before cell phones if you wanted to know where someone was you had to call a land line phone at their house or actually go to where they lived or worked, and this would take a lot of time out of your day either waiting or actually trying to track someone down. If you only needed to tell your spouse something simple like “pick up some milk.” Today people can just send a text message with that information and it is something you receive instantly. This has increased our connection with each other for personal use since we can talk or communicate with someone when and where we want. Cell phones in the business world have evolved even greater than personal use possibly over the same time period. When someone used to work before phones they could only receive calls or email while they were in the office. That could be a good thing, but if something needed to be done urgently or......

Life Cycle Assessment

...The data I collected for Life Cycle assessment was of LCD TV. I was surprised after this study that whatever products we are using is causing at least some environmental damages either during production; transportation or at end of its life cycle stages. Owens is right in quoting Jevons that the economical use of fuel is not equivalent to a diminishing consumption. Same thing I noted in my life cycle assessment of TV that within 5 years alone the consumption of LCD TV rose from 100 million to 200 Million, as many consumers are now purchasing TV for pure aesthetic reasons as it is more energy efficient and prices of productions are also going down with improved technology. Materials on the business and environment (owens, lovin, senge, de botton, documentary) compelled me to think differently. Before reading these materials I was aware of the fact that corporates for their own profits are damaging the environment by emitting greenhouse gases or by polluting the sea or rivers and I was thinking it’s the responsibility of the Governments/Regulatory authorities to control them. But as Senge suggested that: People blame greedy corporations or corrupt government for creating a system that deplete natural resources, destroy species and generate waste but things will not change as long as everyone is blaming someone else. Now onwards every time I had to take buying decision for any product will definitely think about how much carbon foot prints were left in the environment for......

...Cell phones have been around for quite a few years now. The cell phone came out back in 1983. The first design that came out was the Motorola DynaTAC 8000X (2009). Since then we have seen the cell phone evolve from a huge block to what we have today. One of the major problems with cell phones is cell phone waste. When a new phone comes out or we break our phones we usually just throw them away. This causes a lot of waste in the dumps. There is a cell phone though in the works that I feel will help shape the way we build cell phones and other devices, if it can ever get off the drawing board. Every day we throw away millions of cell phone. The reason we throw them away is because they are out of date or they are broken. The problem with the broken cell phones is that usually it is one piece that is broken that is near impossible to fix. So when the average person finds out just how much it is to fix the phone they usually just buy a new one. That’s where Dave Hakkens comes in. Dave’s idea is simple in theory. Build a phone made up of several exchangeable blocks that connect to the base (the middle of the phone) and the base connects everything together.( Mcnicoll & Article, 2013) The blocks have two pins on one side that allows them to be connected to the base. All this is held together by two screws at the bottom of the phone. By doing this you can extend the life of the cell phone by upgrading the specific block on the phone you want. For example let’s say...

Would you be devastated? I sure would. Here are three main reasons why we should ban driving while use of cell phones. Using cell phones while driving is distracting, cell phones while driving impairs you as much as drinking, You can be charged with homicide. Why Using cell phones while driving is distracting. Distracted driving is a dangerous epidemic on America's roadways. In 2012 alone, 3,328 were killed in distracted driving crashes. The number of people killed in distraction-affected crashes decreased slightly from 3,360 in 2011 to 3,328 in 2012. An estimated 421,000 people were injured in motor vehicle crashes involving a distracted driver, this was a nine percent increase from the estimated 387,000 people injured in 2011. 11% of all drivers under the age of 20 involved in fatal crashes were reported as distracted at the time of the crash. This age group has the largest proportion of drivers who were distracted. Driving while using a cell phone reduces the amount of brain activity associated with driving by thirty seven percent Using cell phones while driving impairs you as much as drinking!

...Smartphone Innovations The cell phone has only been available to the consumer for a little over 30 years now. The invention was credited to a Dr. Martin Cooper. Dr. Cooper led the DynaTAC team at Motorola and placed the first cell phone call on April 3, 1973. The first phone was put on the market in October of 1983 and cost about $3,900 plus 50 cents a minute to talk. The phone was about 10 or 11 inches long, about 1 1/2 inches across, and about 4 inches deep. It weighed about 2 1/2 pounds. (Tas Anjarwalla). Cell phones are the most widely accepted consumer technology in the history of the world. According to a report published by Pew Research Center’s Internet & American Life Project, 91% of all adults living in the United States use a mobile phone. The acceptance of this technology is on the rise in the smartphone area as well. The same survey found that 56% of American adults have made the transition to a smartphones (Lee Rainie). Cell phones have made people’s lives easier, safer and more productive. The advantages related to this technology seem to be limitless. With the explosion into the smartphone era, the power of the computer has been placed into the palm of our hand. Access to the internet is now capable from almost from almost anywhere on earth. As the technology advances and the smartphone revolution continues to accelerate, the future innovations look to be impressive. With so many companies competing in the the fast paced development of high tech......

Now, instead of waiting any hours to cook a meal, we can put it in the microwave for a few minutes and the taste will be the same. Similarly, as time goes on, cell phones have been continuously developing from simple device which can just make a call too much more complicated many options such as text messaging, internet processing and sending e-mail. Now, people have chance to contact each other anywhere and at any time. As with any technology that rapidly changes our lives, cell phones have brought both advantages and disadvantages. Cell phones have some negative effects for example, some teenagers become addicted to them and they can cause accidents if used while driving. On the other hand, cell phones also have positive effects such as saving lives in dangerous situations. Some teenagers become addicted to cell phone. The main purpose that we used cell phones in the past was to communicate with someone else who was far away. Because technology has arisen, teenagers now have many choices of ways to contact her relatives and friends both far and near. Texting messages have become a specially popular and some teenagers spend many hours texting. For example, Julie Zingeser, a teen in Rock land has become addicted to text messaging. She sends text all the time when she is at home, school, doing homework and even in bed. The only time she doesn’t text is while she takes showers and plays sports. The total......

Cell Cycle

...the cell cycle, including the steps of Interphase. G1 phase - growth and synthesis. Gap phase 1 begins at the completion of mitosis and cytokinesis and lasts until the beginning of S phase. This phase is generally the longest of the four cell cycle phases and is quite variable in length. During this phase, the cell chooses either to replicate its deoxyribonucleic acid (DNA) or to exit the cell cycle and enter a quiescent state (the G0 phase). S phase Replication of the chromosomes is restricted to one specific portion of interphase, called S phase (DNA synthesis phase), which typically lasts about 6 h. In mammalian cells, the start of S phase—the actual initiation of DNA synthesis—takes place several hours after the cell has committed to carrying out DNA synthesis. During S phase, each chromosome replicates exactly once to form a pair of physically linked sister chromatids. In animal cells, a pair of centrioles is also duplicated during S phase. G2 phase - Preparation for division The portion of interphase that follows S phase is called gap phase 2. Some cells can exit the cell cycle from G2 phase, just as they can from G1 phase. M phase M phase includes the overlapping processes of mitosis and cytokinesis. Mitosis is divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis usually begins during anaphase and ends at a point after the completion of mitosis. At the end of cytokinesis, the parent cell......

...CELL PHONES AND SOCIALIZATION Shawn Powell Strayer University ABSTRACT Cellular phones have come a long way from the exclusive use for important people. Now, the use of cell phones has gone global. People across the global can be seen using cell phones in many ways that fit their life style. This wireless device is used by both the young and the old. The use is a combination of fashion, work and social outlet. Socialization has linked its existence to the invention of the cell phone. CELL PHONES AND SOCIALIZATION The world as we know it has become technology depended on a hand held device called the cellular phone. Martin Cooper was the person who invented the first handheld cellular device in April, 1973. Ever since, the cellular device now commonly known as a cell phone has taken off to a level no one knew it could reach. Today, cell phones have grown to be a new way of everyday life. Additionally, cell phone usage has fallen into the number one category on the charts in the area of mobile communication and/or social interaction as it has multiple uses such as text messaging and surfing the internet. Cell phone conversations take place in public places causing people to interact whether it is for business or pleasure therefore maintaining the balance of social support (Khattab, 2009). However, questions have also been raised as to whether it is proper behavior depending on where a cell phone is being used (Khattab, 2009). Not only are people highly depended......

...Ariana Galindo Mrs. Sgarioto English 1100-400 9 December 2009 The Invisible Killer What if one were to tell you that your cell phone is slowly killing you every time you use it? Cell phones are a part of everyday life for many people across the world. To many their cell phone is considered the most important item they own. People use cell phones everyday for simple tasks. One example is going to the grocery store, when a person forgets what they were supposed to get for mom they simply call her and ask. Imagine thirty years ago? People could never do something like that. Society today relies a great deal on cell phones and their features, but do not realize the potential danger they are putting their health in. Many people around the world use cell phones every day but are unaware of the fatal outcomes linked to them. To understand how potentially harmful cell phones are society must consider the many people using them. There are three billion cell phone users worldwide and more than 260 million in the United States alone (Mead 422). It is shocking that so many people around the world and U.S are cell phone users and they all may not know how harmful cell phones can be. It is important to discover how this technology of cell phones was created and developed in order to look into how it is affecting humans. In 1974, in response to growing demand for a communication system that was more convenient than two- way radios, the Federal Communications Commission (FCC)......

...Today, cell phones have become a necessity rather than a luxury. The history of the cell phone can be traced back to the early ’40s. It was then that police, taxi cabs and other vehicle services began to use two way radios to communicate with one another or a central base. The first “mobile phone” was used by Swedish police in 1947. The technology was limited and drained the car battery after only 6 calls. The technology that we use today, that is towers that send signals in three directions instead of two like a bi-directional antennae, was developed in the 1960s; however, it took decades to mature into the system that we now know and use every day. AT&T petitioned the FCC for a license to use “Cellular Service,” but it was not until 10 years later in 1982 that the request was granted. The “First Generation” cell phones were bulky, weighed several pounds and had a short battery life. This meant they could only be used with any practicality in cars. The first true mobile cell phone was introduced by Motorola in 1983. Weighing in at only 28 ounces, it was light weight. The phone became known as “The Brick Phone” because of its square dimensions. Throughout the ’80s mobile phones grew in popularity, largely due to the fast improvements that were being invented which allowed the phones to become smaller and more powerful. Throughout the ’90s and into the new millennium, cell phones quickly became so common that now almost every adult and most teenagers have one. While......
