Introduction
Industrialization has brought untold wealth and has transformed the way of life in the last century. Industrialization and urbanization have become a global phenomenon, resulting in serious environmental problems such as resource depletion, climate change, and pollution. Large scale use of natural recourses, their polluting processes and transport infrastructure have exacerbated the environmental problems. Since the beginning of industrialization humankind has been utilizing natural resources-coal, oil, gas, water, minerals-at an accelerating rate. Energy resources are an obvious example of limited resources whose uses have major impact on environment in the form of emission of harmful gases and other wastes and also, inevitably, generates carbon dioxide, a gas which plays a key role in the greenhouse ‘global warming’ effect. Rivers are polluted by factories and becoming a health hazard. The dumping of industrial waste into streams is resulting contaminating clean water supplies. There were reports of rivers that had turned orange or had caught on fire, the smog over some cities was becoming intolerable, and there were signs of negative health consequences from buried waste. Environmental concerns have become increasingly central to social policy. The roles of governments in relation to environmental issue are becoming extremely important. A great many of environmental damage problems are due to industrialization and urbanization. Human beings have developed a capacity to create and use tools or what is now called technology. Technology can provide the means for modifying the natural environment for human purpose. Engineers have professional obligations to society. Engineers are called on to seek solutions to problems that have a far reaching impact on society. The solution of such problems requires careful and responsible application of scientific principles. It is necessary for the engineer to address problems

    Modernized agriculture, textile, coal and iron production changed the course of history throughout the world. Despite the fact that the benefits of the industrial revolution are numberless, it also created its own contribution of environmental issues. From pollution of air and water to the reduction of the ozone layer, after centuries later, we are still finding out the full weight and damage that the industrial revolution has caused. As our knowledge of our impact on the planet and the growth of our environment, we are still continuing to take steps to back track the damage. Beginning in the 1970s several laws were enacted. Out of the movement came the “Clean Air Act” of 1970 and the “Clean Water Act” of 1972. The Clean Air Act is the law that most significantly regulates air quality in the United States (Clean Air Act, United States, 2012). This act has been an active effort abaft changes in emission standards in the auto, airline and utility industries (Clean Air Act, United States, 2012)o. Since those…

    Since the beginnings of the Industrial Age in the mid 19th century, the earth has experienced a very rapid increase in the amount of pollutants in the air and the water, due to emissions from automobiles, factories, chemical plants and other manufacturing methods which use fossil fuels, such as coal and petroleum, to create power. But within the last thirty years or so, the amount of pollution in our air and water has reached what some consider as a tipping point, meaning that pollution is slowly yet surely poisoning not only our air and water but also living environments all over the planet. Many proposals have been put forward concerning ways to decrease pollution and to help slow down global warming, yet the causes and effects of air and…

    Environment Pollution has become a major issue during the 20th century as today’s society produces goods which are very harmful to the environment. The Land, water and air are all increasingly affected by a range of pollutants like; noises, heat, smoke, chemicals, manure and radioactive isotopes. Once in the environment, many pollutants are diluted, dispersed or broken down into harmless materials, but other may be concentrated or transformed into more damaging forms. And more importantly , damage caused by pollution may not be covered immediately, because it is not as easy as it seems. “Every year, the burning of fossil fuels releases about 5.6 billion tons of carbon dioxide in the air- an amount that is expected to increase”(Teaser 35). Even though carbon dioxide is a gas that plants survive on, an excess amount proves to be harmful. Carbon dioxide molecules absorb heat energy. The greater the amount of carbon dioxide in the air, the greater amount of heat energy is absorbed, which results in global warming. “In fact, America is the largest carbon dioxide producing nation (Schneider- 33-34).” There are several ways to reduce pollution; however, considering the economic problems America is going through, it’s a difficult issue.…

    Countries have to follow the pathway from high-tech to clean-tech as well as socially sustainable. This requires building of sustainable and self-designing ecosystems, focusing on the direct use of whole or parts of ecosystems which will certainly contribute to the solution of environmental problems in the direction of sustainability. So, the aim in engineering activities is no longer to demonstrate that human beings are able to make everything in life by manipulation. Engineers clearly have to enable developments harmonizing technical, economical, social and ecological systems. Ecotechnology allows improvement in economic…

    Globally both professional and non professional engineers are involved throughout the life cycle of a motor vehicle, from the steel production, to disposal and decommissioning. With a growing global population which is increasing at a rate of 3% per annum (about.com geography, 2011). The current population is estimated to be 6,928,198,253; the use of motor vehicles is steady increasing and the reliance on fossil fuels, with 43.4% of the world’s energy consumption coming from fossil fuels (environmental literacy council, 2008).With the use of fossil fuels such as petroleum in cars, the emissions and subsequent pollution to the environment is increasing. Car exhaust is a large contributor to the emissions along with the mining or harvesting of the raw materials. Petroleum is involved in the construction of rubber, plastics and nylon. It involves the hydrocarbon burning of fossil fuels, significantly contributing to the problem. This report considers the roles of professional and non professional engineers in all steps of cycle, as well as the impacts of emissions.…

    Environmental engineering is a field related to direct application of science and engineering principles to the environment in which animals, humans and plants are living. An environmental engineer as a professional is concerned to protect the environment from deterioration; he is also concerned with the preservation of resources including plants, fuels, and fossils which can generate energy for human use. The primary task of an environmental engineer is to provide maximum protection to the environment by protecting public health, preserving the current condition of water, plants and other resources, and improving the present condition of these resources. These tasks can be achieved by technological applications in the fields of air quality management, water supply and treatment, and environmental impacts measurement and mitigation. For this purpose, an environmental engineering course is designed to prepare a graduate with necessary skills and abilities in the environmental technology area, so that he can turn out to be a good protector of the environment. Today, many highly qualified and intelligent people are working in this field, but Able Wolman is the biggest source of inspiration for many people who intend to play their role in environmental preservation. His work in the field of water purification and sanitary engineering is still a good source of information for students, as he is supposed to be a pioneer in this field. Able Wolman was born in Baltimore, Maryland in June, 1892 and died in Feb, 1989; he worked tremendously for clean and healthy water supply for citizens in his area.…

    The profession of environmental engineer can be divided into two distinct areas; the first being focused on public health and the second being focused on development of new technologies to remediate environmental damage. The first area of public health is historically where environmental engineers began their work. Examples of jobs in this area include waste management, pollution control and resource allocation.1 A specific example is the design and construction of a public water system able to bring clean drinking water to a population and then dispose of wastewater in an environmentally sound manner. The area also includes design and implementation of controls in industry to promote industrial hygiene and protection from harmful chemicals and radiation. The second area in which the field has seen a great deal of new growth is in the area of environmental remediation. The collection of harmful particulates from power plants to reduce acid rain, cleaning of oil spills, and development of recycling programs are all areas in which environmental engineers have had success in their fields. The destabilization of ecosystems from the byproducts of modern…

    The industrial revolution brought success to the civilized world but it also brought a nightmare called "pollution." In the past decade we've become more environmentally conscious of our planet, but for almost a century we've been a "throw-away" society with an out-of-sight, out-of-mind mentality. Industrial smoke has polluted our air, whole communities have been built over nuclear waste landfills, fish and wildlife have died in our once pristine streams and rivers and our rain forests are being leveled to make room for strip malls and bigger cities. The world's dependence on fossil fuel turned the Kuwait desert into a burning inferno for six months and oil spills like the one in Alaska are becoming more frequent.…

    Smith (1997) states that many factors have necessitated governments to re-think critically on the issue of improvement of economic and environmental policies. Management of natural resources is one key area where environmental policy makers have to reckon with. The increase in human activity has had serous effects on the environment. For instance, mushrooming of industries in the major cities of the world has resulted in increased carbon dioxide concentration and other gases in the atmosphere. This has had a direct impact on the human health who is the major work force in driving the economy of countries involved. Likewise, there is increase of global warming hence resulting in flooding or increased…

    The industrial revolution in the 18th and 19th century saw the progress of human kind in manufacturing and energy. The source of this revolution was the discovery of minerals and fossil fuels, which the human race started to exploit without thinking of the consequences on the environment. Fossil fuels were burnt for energy and mines were being dug for minerals without realizing that these activities would alter our atmosphere. It was in the late 20 th century when the comity of nations realized that the past activates have taken a toll on the environment, consequences like “Global Warming” and “Climate Change” have become evident from scientific study, which heralded a need for “Sustainable Development” if the environment is to be protected from further degradation. In 1969 the United States formed a national policy for environmental sustainability by virtue of National Environmental Policy Act (NEPA) with the aim to “foster and promote the general welfare, to create and maintain conditions under which man and nature can exist in productive harmony and fulfill the social, economic and other requirements of present and future generations”.1 In 1972 the Stockholm Conference reiterated the need to protect the environment and a resolution from the participant governments to use the resources of the earth in a responsible manner.2 But, the need and immediate action on Sustainable…

    Environmental degradation is one of the ‘10 Threats’ identified by the High Level Threat Panel1 of the United Nations. Degradation of the environment refers to deterioration of the environmental condition by the depletion of natural resources such as water, air and soil, as well as the destruction of habitats and loss of biodiversity. Such degradation, such as pollution, leads to global warming – the increase in the average temperature of the Earth’s surface. According to National Oceanic and Atmospheric Administration (NOAA) and NASA data, ‘the Earth's average surface temperature has increased by about 1.2 to 1.4ºF in the last 100 years.’2 The earth is experiencing rapid and severe climate change and environmental problems that people of the world can no longer overlook the crisis and not do anything. This research papers aim at first giving an overview of the problems the world is facing now, then explore solutions attempted by international efforts, or are possible in effect, that are targeted at environmental issues. Pollution designates the ‘undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities.’3 There are numerous kinds of pollution taking place everywhere in the world as of today. For example, exhaust gases of vehicles, combustion of coal and acid rain, which make up the term ‘air pollution’, are very much detrimental to the natural environment. They are also the main contributors to global warming.…
