The History Of Contact Lenses
Sunday, September 5th, 2010The History Of Leaflet Distribution
Monday, August 30th, 2010Distribution of brochures is an extremely effective way to convey a message directly to market. Distribution of leaflets to a message in the hands or the mailboxes of a target market. This is an extremely popular form of marketing is particularly effective in the promotion of services or products that are specific to particular regions. The procedure for obtaining the leaflets is fairly rudimentary. Brochures are personal to addresses that are provided furnished or delivered by hand to the people walking down a street. The flyer distribution is probably their flyers in the hands of the most important demographic groups marketplace. If the Flyers to promote a party event for young pilots, is to young people who look like they are part of a distributed, so that when the Flyers to promote women’s clothes, then the merchant will pass on women flyers. Leaflet drops have historically been very popular methods of dissemination of political messages have been. Political messages are often difficult to get to their target audience. In many situations it is the case that the government is fighting against the political groups fighting for press coverage for their entries – in the fear of consequences, and therefore the most effective method for transmitting messages to guests, they were distributing brochures and leaflets. This as an extremely effective method of transmitting a message and one of the worst examples was seen as successful, was the use of the distribution of leaflets by the Nazi government during World War II. The Nazi government used the distribution of leaflets to be false information about the Jewish community spread. This is said to have contributed to a change in public opinion, facilitate and contributed to the atrocities followed. There is also a long history of distributing leaflets occurs in a number of different wars and periods of political instability. It has been used in a variety of controversial situations, including the so-called psychological warfare. The role of leaflets is to change the behavior of people in war-torn region to the cause of a particular group to continue to support. In many such cases, the leaflets in the region through the leaflet drop had fallen in the air. These leaflets are then meant to be read by people in the region to change their views on a topic, or to encourage them to perform a certain action. These leaflets are highly politicized and although they often try to appear as a balanced message almost always focus on the one hand provide an argument. The role of propaganda leaflet was defined in six different categories. These categories differ from each other and they were used during the last century. Leaflets were used to the people or the troops that they could threaten programs. Brochures have been sent to callers to leave and abandon their resistance. They have also been sent to offer rewards and have information that shows the opposition in a bad light, appealed. Brochures have also been used by many stakeholders to promote communication between groups and blood revenge, the need for peace. There were also a number of examples of leaflets that were distributed in humanitarian programs to the people how they can inform and support to help in the search.
Oral History: a Viable Methodology for 21st Century Educational Administration Research: National Impact
Saturday, August 7th, 2010Oral History: a viable methodology for the 21st Century Administration of Educational Research: National Impact _______________________________________________________________________ ABSTRACT This article identifies 21st Century three realities to redefine that research in educational administration: 1) the growing need for authenticity and relevance in the fight against the community and school problem-solving contexts, 2) the need for a method of research that the way of depth interviews competent people with a minimum of Institutional Review Board (IRB) oversight, and 3) provides a methodology that can be facilitated by new technologies. Oral history has been used in many disciplines, but rarely used in educational administration. It offers some promise, and the authors point to possible uses and interpretations of the history of the project by the oral and an oral history project proposed has been completed. ______________________________________________________________________________ The purpose of the article The aim of this paper is to examine oral history interviews and historical research as a viable method of research within the wider family of research methods in educational administration and educational leadership. The development of research methods in educational administration has been influenced by the changing paradigms, changing needs, increasing the Institutional Review Board (IRB) oversight, and technological change. Research administration for the formation of other disciplines in that it distinguishes includes the ability to search for new and innovative ways to use the results of research on problem solving and decision making in schools. Research in Educational Administration in the wake of the transformation Research for the general administration has had a very last century. Principles of corporate governance from the industry dominated the first half of the 20th Century school administration thought. During the 1950s and 1960s, various social science methods and concepts form a new generation of thinking of education administration and research methodology (Campbell, Fleming, Newell & Bennion, 1987, Murphy 2003, Fall). Methods of science in the late 1980s and social workers have been completed, but not pulled through qualitative methods from anthropology replaced. Action research fills a niche Education Research administration. There is less emphasis on formal theoretical constructions while focusing on authentic collection of data on campus, and the solution of problems. The continued growth in the acceptance of research methods from other disciplines has been described by Campbell, et al: Educational Administration is an applied field rather than an academic discipline. He does not shoot a single body of literature, or use a single set of scientific tools … an area must have a vital interest not only with more knowledge, but also to improve the practice … Also … an area must be at all concerned with problems – based on the methods of different disciplines. (1987, p. 3) Not all influences on the research-management education in the 21st Century were methodical. An increase in the National Institutional Review Board (IRB) oversight has greatly influenced research in educational administration (Herrington & Kritsonis, 2006). There are still large differences between universities in the extent to which educational research is subject to the supervision of the IRB. Some universities, free education, science and monitoring IRB fully, particularly studies that sought to improve the quality used in schools or the activities of research for the classroom monitor. Some universities require a full investigation of all aspects of research, regardless of the method or use of the data. Navigating the maze of restrictions on the IRB to certain institutions has led to avoidance of certain methods of research or of the population and in some cases, the research resulted quite small (Herrington & Kritsonis, 2006). The technology has the most forms of research much more practical and has made it possible. For example, more user-friendly Windows or UNIX statistical software such as Stat-Pac (Statistical Package for Social Sciences (SPSS) and SAS have worked hand-calculations replaced punched card data and mainframe versions of statistical software. Qualitative research have access to software coding as Hyper RESEARCH 6 2 7 Computer Aided NVivo Qualitative Data Analysis (QAQDAS 2007) to help high volume of qualitative data encryption capabilities. Audio and video recording equipment, imaging equipment and related software still orally for the taking history will continue to develop analog recording of oral history more professionals are preferred. The challenge for researchers in education in the 21st Century is a process that a suitable framework for education issues in specific contexts that are stored reliably and accurately can choose to discuss. The methodology must also produce a study that is accessible within a reasonable, affordable and must comply with ethical requirements and minimize the need for control of the IRB. A methodology pending Charlton (1985) is defined as oral history “The recording and preservation of the planned interviews with selected individuals in a position to relate the collected memory, and thus the reconstruction of the past” (p. 2). Wood (1978) is defined as oral history: 1st a tape recorded interviews or surveys, in the form of questions and answers 2nd Interview conducted with a few, preferably the more the better discuss the knowledge on the subject, 3rd an interview with the competent someone what he or she speaks from personal participation or observation (sometimes we do give a second-hand account) 4th Topics [historical or community] … 5th accessible, ultimately, into strips and / or transcripts in a wide range of researchers. (Pp 389-390) The value of oral history to educational researchers and practitioners in the background that, by credible actors who are able can be provided to enrich the understanding of the direct connection with the resolution of problems or who may be parallels with other contexts. Sometimes tragic events or important events have a voice to silent observers or groups that give the true nature of the problem of interest to know, but have never been consulted by historians and politicians. For example, ethnographic changes have in recent years significant cultural divides in communities and schools, the most demanding long-held assumptions of teachers and administrators are created on their student clients. One example is in older suburban and rural sites have found that the school in 1995-2004 compared with the following demographic changes in students and teachers showed. In 1995, only 17 percent of the students on this campus center were Hispanic, 15 percent were African American, 65 percent of students were Anglo. The teacher demographic performances were similar. Ten years later, 67 percent of students are Hispanic, 17 percent were African American, but only 16 were Anglo students. The demography of teachers has remained relatively unchanged over the same 10 years. Interviews with parents, teachers and administrators showed that the unexpected differences in demographic developments during the period of ten years to increase racial tension, in which teachers and pupils and teachers / parents led conflicts arise. The performance of Spanish students continue a downward spiral, absenteeism and increase termination, and disciplinary alternative education placements were on the rise. These realities make the district in danger of losing his position on national criteria and standards of NCLB. This was a phenomenon that could be documented through oral history interviews and the results are made available as a case for other districts. In this case, a number of interventions, the short term, but a comprehensive and effective planning for the long term plan carefully conducted oral history, a useful context and history informs community of the community, can provide the answers of all parties to the problem affects work. Another example is the fact that during the 1960s and 1970s, the cornerstone of education and experience for the first generation of Mexican-American College and rectors and chancellors of the State of Texas, nation states have in place in a cultural and educational environment South Texas, was hostile to the aspirations and future progress of Latinos (Herrington made, 1993, August). What can be learned through education and mentoring experiences of these highly successful people is invaluable for educators and people of other minorities in vocational education and decisions. These two scenarios very real, albeit without reference to a specific context. There are lessons, the teachers and administrators at the school during the dramatic demographic changes (study proposed but not yet implemented) could learn from the study of South Texas for the success of Hispanic students, who grew up in communities that between 30 and 40 years earlier resembled their current demographic and cultural realities. The communities already struggling to cope with the realities of continual change can overcome the demographic landscape much to look up from their predecessors in the South Texas, just because these experiments have already been recorded and transcribed (Herrington, 1993, learn to August). The thoughts and feelings of those Hispanic people on their experiences, parents, teachers and mentors (many of whom were Anglo and Hispanic) are successfully and eloquently recorded for posterity. Their stories show, personal strategies and important people, once a helping hand. In both cases, the method of oral history, this may be the only way to be otherwise inaccessible information. Regarding the oral history Hoffman (1974) writes: His greatest asset … It is possible that the preservation of the life experience of people who have no time to make … to write their memories … Interviews with people who are foot soldiers in the various social movements were important, but were not previously registered can now be preserved and therefore assess its impact. (P. 26) The role of history in the education reform The researchers have identified several uses of history in educational research. History can help the implementation of welfare reform, future trends to anticipate or influence the practice through the training of educators (Borg and Gall, 1983). Comparing the work of the historian, that the psychotherapist Borg made et al, that history has a liberating role, particularly for educators: For Freud, neurosis is the inability to leave the past, the burden of its history. What is deformed and pushed back will be replayed forever. The task of the psychotherapist is to help the patient to reconstruct the past. In this context, the goal of historians at the therapist – to help ourselves from the burden of the past in us, for free. (P. 802) It is our common understanding of the history and the ability to learn from our common past, which man differs from all other living beings. Wector (1957, August) wrote: Monkey is a stack of empty boxes and a banana out of reach soon learns from experience. But the man only learns from the experience of others. The history makes it possible. In the broadest sense, everything we know, is history. More precisely, the roadmap of the past. (P. 24) History is our collective memory. The ability to use history and extract useful generalizations and theories of man is unique. Without a record of the past, we are left to the course of life without the help of those who preceded us navigate. In a posthumously published essay convincing, Kennedy (1964, February) a number of reasons for the study of historical records. He stated: There is little that is more important … without [history] … [A] is uncertain and defenseless before the world, knowing neither where he came from or where it goes. With this knowledge, it is no longer alone, but draws a much larger force than his own cumulative experiences of the past and the vision of the future. (P. 3) CER oral history And technological considerations History of historical research, particularly oral evidence provides the context and clear precedents that can be investigated and treated for educational policy and practice can. Educational researchers and members of the Council of the IRB might wince at the idea of preserving the recorded interviews. This practice seems contrary to the ethical rules preserve the anonymity of subjects. That is the difference between the oral history interviews and other methods is important. Unlike other discipline or methodology, oral history interviews, the words of a person named connected requires time and place by the recording of data on audio cassettes, video tapes, photographs, documents, transcripts and maintained as accessible for historical verification (Dunaway, DK & Baum, 1984). To address the concerns of ethics, the Organization of American Historians (OAH) and the Oral History Society (OHS) in October 2003 successfully, the Office of the United States in search of protection called (OHRP), part of the Department of Health and Human Services, for a special decision on the research of oral history interview. They are especially with oral history projects that are not defined with the type of research from HHS regulations in question. It was found that not some oral history projects under the rule of autumn “common” (45 CFR Part 46) defines research as “a systematic investigation to develop, including research, development, testing and evaluation, or contribute to generalizable knowledge . After the organization of oral history (2003, November): This type of research include standard questionnaires with large samples of people who are not anonymous and open interviews with identifiable people, their interviews with “informed consent” to remain that give oral history characterized. Only those projects, the oral history of the regulatory definition of research must meet to write now submit their research protocols for IRB. (P. 17) One advantage of the oral history interview, so if the study is carefully designed, is that, the monitoring of the IRB are much less restrictive than other methods. Concluding Remarks In conclusion, the method of oral history-technology intensive. 21st simplify century technologies and existing technologies and expand the capacity of the oral history, both for gathering information and presenting information in a variety of formats. Digitization of voice, image, video, text and materials have significantly the lead times and production to produce and present the results of the reduced oral history. Finally, oral history interviews, has more than ever, a huge potential to provide not to mention the voice actors, but important in the arena of social change – including the community and school. learned for any other change in our school system educational managers and scientists to find ways to listen to those voices unpublished. Well-studies that the voices of people who can consent rich historically and contextually specific information on time with minimal supervision of the IRB was designed. Finally, technology is rapidly expanding the repertoire of formats for the archiving and presentation very useful and useable knowledge to facilitate the school to promote. References Baum, W. K.

Shedding Light on the History of the Light Bulb and Its Bright Future
Sunday, July 11th, 2010Read by candlelight romantic like, but it’s hard on the eyes, and a stray breeze all leaves in the dark. Imagine, a torch in the oil-soaked for a small fee, light, flashlight outside. Thank God we have the light bulb, and thank God, we were always doing better and better. Of strips of charcoal glowing light-emitting diode (LED), we have come a long way. First Light: The Beginning Sun It was a dark and stormy – Well, it certainly was a dark night, but that will soon change. The year was 1809, and learned English under the name of Sir Humphry Davy was about the world a better place to another. He came with a rudimentary battery, which he accompanied his son. Between the son, he made two pieces of charcoal, which can – we only accept – surprised when they began to glow. Thus, the light bulb has been designed, or at least arc, the phenomenon that has the glow of the coals Davy, was discovered. It was not until 1820 that Warren De La Rue has tried to produce the first light bulbs. Enclosing a platinum coil inside a vacuum tube, he runs a current through and there was light. Longevity has improved considerably strips of carbon Davy, but the cost was prohibitively expensive platinum. Success! A little more light on the subject Working with so many scientists around the world have joined to produce a practical lamp, it was only a matter of time until someone made it right. In 1879, what happened – twice. Thomas Alva Edison and Swan Wilson had pierced independent. Both models were on a carbon fiber filament, which was based made from cotton. Although a big step in the right direction, this bulb has lasted for 13 rare. 5:00. Edison redoubled his efforts to create a permanent light, and only a year later, he developed a bamboo-derived filament that could last for over a thousand hours. Further developments will come, but years later. Karl Auer uses a filament of osmium in 1898. In 1903, Siemens and Halske, a team of German engineers used tantalum. The evolution and its Auer improved light bulb burn time. 1906-1910 saw the development of ductile tungsten and its use in a light bulb. Thank you for the efforts of William Coolidge and General Electric Company, it became common practice, a long burning light for us most of the twentieth century. Some improvements have been made to prevent the tungsten from the combustion and coating inside the lamp soot. The gases were added to stop the soot, argon and nitrogen was found that also carry the heat of the filament, making it even longer. Seeing things from a different angle When all the excitement that was light bulbs go, around 1857, a French physicist named Alexander E. Becquerel was put in his time of fluorescence and phosphorescence. He experimented with different tubes and coatings, but never quite had the success. A German physicist Julius Plucker, and a glass-blower Heinrich Geissler, met in the mid-1800s to the continuation of the work of Becquerel. They found that an electric light through a glass tube with tiny amounts of gas. As the forerunner of French, they do not have much success. There were of course many others are trying to produce lamps practice, but they also failed. Without all their work, when Peter Cooper Hewitt would not have been possible to produce the first mercury vapor lamp in 1901. This lamp was the ancestor of the fluorescent lamps, we have today that use electricity to excite mercury vapor lamps to create. Beginning to see the light: a better future Emergence Electroluminescence, discovered by the Englishman Henry J. Round in 1907, not only the sound cool the basic principle of light emitting diodes (LEDs). The first LED was independently created by Henry J. Round by a Russian scientist Oleg Vladimirovich Losev name in the mid-1920s. No practical benefit has emerged in decades, though. In 1955, Rubin Braunstein that simple diode with gallium antimonide (DSR), gallium arsenide (GaAs), indium phosphide (InP) and silicon-germanium (SiGe) is any product-infrared light. patented in 1961, the first infrared LED Bob Biard and Gary Pittman, was he using GaAs. All that scientists have intensively conducted in 1962 Nick Holonyak Jr. invented the first visible spectrum LEDs. He earned the title of Father of the LED for it. It was not until 1976 that high-brightness LED was invented by high efficiency TP Pearsall. Despite the hefty price at the time, used Hewlett Packard, the red LED shows the first pocket calculator, alphanumeric. Since the birth of LED practice in the 1960s, their efficiency and light output increased exponentially, doubling every 36 months. Organic light emitting diodes (OLEDs) are now used to make thinner displays the highest resolution of all times, and they are just one of many innovations LEDs. LED Lighting the Way LED lights are extremely efficient, benefiting from a company with 80-90 percent energy savings over incandescent lamps archaic in appearance, while the production of similar brightness. Not only that, but the LED lamps can be over 100,000 hours, more than eleven and a half years of constant burning last. Her versatility is amazing. Used by hikers in ultra-light, ultra-bright projectors, automobile manufacturers as a stylish, very functional lighting and engineers in the state of the art technology in fiber optics, these lamps can do little to almost everything. You can even replace almost all other lights are already in use, at home, at your local stadium. Another advantage of LED lamps are environmentally friendly and sip not only for their power options. The push for compact fluorescent lamps use mercury in homes across the country. LED lamps last longer, light immediately run to replace silence, a broader range of other bulbs (including halogen lamps), are more durable because of their design for Solid State Research and contain no toxic elements. The next time the light goes out at your house, check and replace it with a LED lamp. It could be your brilliant idea for the moment.
Sustainable Development: a History of Two Words and Few Facts
Wednesday, June 16th, 2010In Spanish at http://www. . Inpsicon com / news. php? to extend. 206www. . Inpsicon com In 1987, the United Nations Environment Programme, who has worked by former Norwegian Prime Minister Gro Harlem Brundtland headed, examines the situation of today’s world and proven by scientific evidence that global society was to destroy the impact on the environment and a broad population in the world by submitting them to poverty. This analysis was published in a book entitled “Our Common Future”, on the conclusions of the Brundtland Report. This report introduces the concept of sustainability (or sustainable development) has been used for the first time, defined as meeting the needs met of the present without future generations. The purpose of the Brundtland report was a practical tool to find the development and environmental issues back. To achieve this objective, the Commission for three years for public hearings and received over 500 written comments subsequently examined by scientists and policy makers from 21 countries and different ideologies. As the title says. the work of so many people with different histories and cultures, the strengthening of dialogue is necessary, why the result of this synergy is more than any of them individually obtained. However, the concept that the concept of sustainable development is surrounded by the year 1987 Gestated session. In fact, in June 1972 was the declaration by the United Nations Conference in Stockholm, where the environment of man and the two basic aspects that compose it: the artificial and have native, we actively discussed. Is it appropriate, the results show that the high point of concern for the index of the contamination and inequality in the conditions necessary for development. It is clear that, even if the concept of sustainable development was established in 1987, some events in the world has the need to define development and design, including an interdependent and fair view check revealed. The subject was discussed in the increase and several scenes. After ten years of the United Nations Conference 1972 in May 1982 in Nairobi (Africa), took place a further conference, with its central axis was the environment. Once again, the themes and content into a new mandate were addressed included: sustainable development. The impact of the Brundtland report, can be achieved, including the new legislature will be confirmed in the following Conference of the United Nations called the Earth Summit in Rio de Janeiro, 1992. What was at previous conferences on the general theme on the ideas and concerns at the Earth Summit goals and guidelines were developed to protect our planet. So, has represented for the first time in history, 180 countries at the Earth Summit, the name of climate change recorded contract, to take measures to mitigate the effects it produces, due to increased emissions of greenhouse gases. Currently there are 181 governments that are Parties to the Treaty, which meets annually to review progress and continue the search for solutions to problems. Sometime later, in 1997, all countries with climate change compromise is met in Kyoto, Japan, and laid the foundations for the commitment, to reduce emissions by 7% in the next decade, reaching a commitment from the countries met in Rio five years earlier. In 1998, the industrialized countries reduce their emissions by up to 10% increase, for example, the U.S. has exceeded more than 20%. In the same year, the Kyoto meeting, was the second World Summit held at United Nations Headquarters in New York. But if you set the balance at the first Summit of Rio de Janeiro and reaches the same, the result is discouraging. Although the arrangements were confirmed, set the objectives for the damage that was to stop the planet is not reached. In fact, the globalization of the economy, the progress of the Rio Agenda destroyed has reached up a business in the world and exposed to natural resources, the voracity of the market. These are typical signs of warning: • In many places in North America have registered their summer days or the end of the decade of 1990. has included • Since 1980, the Earth’s 19 hottest years were 1998, the warmest, with 2002 and 2003 as the second and third respectively. • In 2003, extreme heat waves caused more than 20 000 deaths in Europe and on first 500 dead in India. • Wear the mosquitoes, the diseases themselves are advocating that climate change will allow them in areas that were previously inhospitable, they were to survive. Mosquitoes that can carry dengue virus in up to a height limit. 000 meters, but they have recently Surfaced 2. 200 meters in the Andes of Colombia. Malaria, in higher regions of Indonesia, was also demonstrated. • According to NASA, the polar ice cap is melting at an alarming rate of 9% per decade. In the decade of 1960, the thickness of Arctic sea ice has decreased by 40%. • The current rate of sea level rise is three times higher than the historical rate and appears to accelerate. • A recent study published in the prestigious Nature publication discovered that at least 279 species of plants and animals already a response to global warming. The geographical distribution of species has poleward at an average of 6.5 kilometers (4 miles) per decade, and their drives are moved from an average of 2 days before each decade. • In the past 25 years, some penguin populations by 33% in some parts of Antarctica was by reducing the sea ice habitat in winter. The hidden significance of the disagreement focuses on the form of addressing the problem. In other words, all participating countries agree with the existence of the current problem of development models, but no one comes in the forms of implementation of solutions. This is because these solutions require adaptation of economic growth, well-being of the planet as an ecosystem, that modern Western society has never seen. Since the outbreak of the concept of sustainable development in the year 1987, its importance focused on ecological sustainability, which can lead to a domino effect of global summits and meetings, the need to reaffirm faced the same problem: the satisfaction of human needs is not over time in a sustainable, how future generations will not be considered with the same resources we have are made now. With meetings held since then, we can select the Nobel Prize in 1998 in 63 countries drafted a Manifesto of the affirmation of the global climate crisis in 1997, before the signing of the Kyoto Protocol in Japan. In the same year the Treaty of Rome by focusing on the proper use of fertile land was celebrated. Sometime later, in 1998, Lisbon Expo focuses on the protection of the oceans. In 2000, the climate summit in The Hague, Netherlands, finishing once again that the goals were not achieved held. In 2002 in Johannesburg, South Africa, another Earth Summit came with similar results. (Http: / / www. Gencat. Net/mediamb/revista/rev33 votes.

Granted, not always those that have the greatest force in this debate, most countries contamination of the planet. An example appeared that recently a documentary, titled “An Inconvenient Truth, sponsored by Al Gore, who has played an important role in the political positioning of this problem in the United States. The documentary retreat of glaciers shows many photographs, which shows several years, and a study by researchers at the University of Berna Physic Institute and the EPIC data, the ice core from Antarctica, with concentrations of carbon dioxide in our days more than during the last 650,000 years. Similarly, this documentary shows a study by Dr. Naomi Oreskes (2004), a review of 928 scientific articles on climate change published 1993-2003 is carried out. The survey, published in the journal Science, showed that each element is global warming blamed on human action or make any comment on that at all. The scientific basis of this document, to our planet are large in a critical and unprecedented and show, now more than ever, the awakening of environmental awareness is necessary, based on a perspective of sustainable development, achieving a balanced coexistence with the ecosystem that our lives as types supported. Improving the environment is a commitment of companies and citizens. At the beginning of this phase, great sacrifice, or innovative methods and heavy, are not necessary, the solution is simpler than we thought, it is in your hands.

Pdf): 1 – Changing the bulb Replacing one regular light bulb with a compact fluorescent bulb saves 150 pounds of carbon dioxide per year. 2nd – Drive less Walk, bike, car pool or use public transport more often. You’ll be a pound of carbon dioxide for every mile you drive to not save! 3rd – Recycle more You can record second 400 pounds of carbon dioxide per year by recycling just half your household waste. 4th – Check the tires Properly inflated tires can improve gas mileage by more than 3%. Each gallon of gasoline saved keeps 20 pounds of carbon dioxide from the atmosphere! 5th – Use less hot water It takes a lot of energy to heat water. Use less hot water by the installation of a low flow showerhead (350 kilograms of CO2 per year) and washing your clothes in cold or lukewarm water (500 pounds saved per year) 6th – Avoid products with lots of packaging material You can a. 200 pounds of carbon dioxide, if you reduce your garbage by 10%. 7th – Set your thermostat Move your thermostat 2 degrees in winter and up 2 degrees in summer. You could save about 2. 000 pounds of carbon dioxide a year with this simple adjustment. 8th – Plant a tree A single tree absorbs one tonne of carbon dioxide during its life. 9th – Turn off Electronics Simply switching off your TV, DVD player, stereo and computer when you are not saved with them thousands of pounds of carbon dioxide per year. 10th – Be part of the solution Spread the world!
