Environmental protection

Environmental protection has become a major concern for society. Admittedly, with the rapid development of economy, our environment is faced with new challenges. People increasingly attach importance to the protection. So it has been common that teachers and students discuss environmental protection in class. City planners take environmental problems into consideration as well. Factories are no exception. They begin to try reducing pollution to meet the needs of environmental protection instead of the short-term interest.

The main reasons are listed as follows: firstly, the serious air and water pollution affects everyone. In addition, only by making joint efforts to protect our environment can cities survive. Last but not least, businesses to make a profit pay more attention to environmental protection for their interest in the long run. From the picture above, we can see even the communication between parents and son rely on the Internet. With the rapid development of advanced science and technology, people increasingly make full use of the Internet to communicate with each other instead of face-to-face contact. As far as I am concerned, electronic communication only partly replace face-to-face contact. Admittedly, the Internet’s being put into use widely is the inevitable result of social development. It is indispensable to our daily communication. In addition, there is no denying that the electronic communication does save plenty of time for us, we can communicate easily beyond the limit of time and place.

But every cion has its two sides. People are meeting increasingly on the Internet, on television screens. Undoubtedly, it is not beneficial to the deepen the emotions and between people. We cannot express our feelings fully without face-to-face contact as well. Some body language like a hug of comfort or a kiss of love will never be express through the electronic communication. Therefore, though the electronic communication bring convenience to us, to some degree, electronic communication can never replace face-to-face contact. My View on Traffic Accidents In recent years, plenty of news about people injured or killed by cars on roads can be heard , which shows us that traffic accidents have been risen. But why are there so many such terrible events? As far as I am concerned, to begin with, it is the result of more cars are running on the roads with the development of economy.

Increasing accidents follow the increasing cars. In addition, there is no denying that the road conditions sometimes can’t meet the requirement of cars. But I think the most important one point is the lack of the safety awareness. And when being drunk, most people insist driving .As we all know, quite a lot of traffic accidents are due to the drivers who drive cars after drinking. Drunk drivers’ mind is vague, and they can’t control themselves and the car well, so they can easily get into trouble out of consciousness.

Environmental Protection

What is your carbon foot print?
A carbon footprint has historically been defined by Championne as “the total sets of greenhouse gas (GHG) emissions caused by an organization, event, product or person.”[1] However, calculating the total carbon footprint is impossible due to the large amount of data required and the fact that carbon dioxide can be produced by natural occurrences. It is for this reason that Wright, Kemp, and Williams, writing in the journal Carbon Management, have suggested a more practicable definition: “A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest. Calculated as carbon dioxide equivalent (CO2e) using the relevant 100-year global warming potential (GWP100).”[2] Greenhouse gases can be emitted through transport, land clearance, and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, and services.[3]

For simplicity of reporting, it is often expressed in terms of the amount of carbon dioxide, or its equivalent of other GHGs, emitted. Most of the carbon footprint emissions for the average U.S. household come from “indirect” sources, i.e. fuel burned to produce goods far away from the final consumer. These are distinguished from emissions which come from burning fuel directly in one’s car or stove, commonly referred to as “direct” sources of the consumer’s carbon footprint.[4] The concept name of the carbon footprint originates from ecological footprint,discussion,[5] which was developed by Rees and Wackernagel in the 1990s which estimates the number of “earths” that would theoretically be required if everyone on the planet consumed resources at the same level as the person calculating their ecological footprint. However, carbon footprints are much more specific than ecological footprints since they measure direct emissions of gasses that cause climate change into the atmosphere. Measuring Carbon Footprints

An individual’s, nation’s, or organization’s carbon footprint can be measured by undertaking a GHG emissions assessment or other calculative activities denoted as carbon accounting. Once the size of a carbon footprint is known, a strategy can be devised to reduce it, e.g. by technological developments, better process and product management, changed Green Public or Private Procurement (GPP), carbon capture, consumption strategies, and others. Several free online carbon footprint calculators exist, with at least one supported by publicly available peer-reviewed data and calculations from the University of California, Berkeley’s CoolClimate Network research consortium.[6][7] These websites ask you to answer some basic questions about your diet, transportation choices, home size, shopping and recreational activities, usage of electricity, heating, and heavy appliances such as dryers and refrigerators, and so on.

The website then estimates your carbon footprint based on your answers to these questions. The mitigation of carbon footprints through the development of alternative projects, such as solar or wind energy or reforestation, represents one way of reducing a carbon footprint and is often known as Carbon offsetting. The main influences on carbon footprints include population, economic output, and energy and carbon intensity of the economy.[8] These factors are the main targets of individuals and businesses in order to decrease carbon footprints. Scholars suggest the most effective way to decrease a carbon footprint is to either decrease the amount of energy needed for production or to decrease the dependence on carbon emitting fuels

How has engineering changed us?
As we enter the twenty-first century, we must embark on a worldwide transition to a more holistic approach to engineering. This will require: (1) a major paradigm shift from control of nature to participation with nature; (2) an awareness of ecosystems, ecosystems services, and the preservation and restoration of natural capital; and (3) a new mindset of the mutual enhancement of nature and humans that embraces the principles of sustainable development, renewable resources management, appropriate technology. During the past several centuries, the successive development of the printing press, wired and wireless communication, and the Internet have enabled the ubiquitous creation, shaping, and sharing of knowledge.

One could argue that as a result of these developments, the capacity for universal participation in decisionmaking in politics and other spheres has risen to an unprecedented level, as has the potential for enhancing the quality of life for a broader segment of humankind. Today, a new world of robust communication lies before us, and it has all been made possible by the talents, skills, and dedicated work of engineers and scientists. How we develop and use this capacity will determine our destiny. The essence of engineering, on the other hand, is integrating all knowledge for some purpose. As society’s “master integrators,” engineers must provide leadership in the concurrent and interactive processes of innovation and wealth creation. The engineer must be able to work across many different disciplines and fields–and make the connections that will lead to deeper insights, more creative solutions, and getting things done. In a poetic sense, paraphrasing the words of Italo Calvino (1988), the engineer must be adept at correlating exactitude with chaos to bring visions into focus.

How can we create a sustainable community?
There are many definitions and there are many different ways for communities to attain a more sustainable future. The sustainability of a community depends on creating and maintaining its economic and environmental health, promoting social equity, and fostering broad-based citizen participation in planning and implementation. Communities that engage citizens and institutions to develop sustainability principles and a collective vision for the future and that apply an integrative approach to environmental, economic, and social goals are generally likely to be more successful. Job creation, energy use, housing, transportation, education and health are considered complementary parts of the whole. Since all issues are interconnected they must be addressed as a system. The process includes: • broad and diverse involvement of citizens

• the creation of a collective vision for the future
• the development of principles of sustainability
• an inventory of existing assets and resources and additional assets that would benefit the community • clear, measurable goals
• the development of community indicators to evaluate progress • open and transparent communication
• early, visible results
• celebration of success
Sustainability is a process of continuous improvement so communities constantly evolve and make changes to accomplish their goals. The initiatives and resources on this website have been selected to help you learn about ways to make your community healthier, safer, greener, more livable, and more prosperous.

How can renewable energies transform our society?
Renewable energy is important because of the benefits it provides. The key benefits are: Environmental Benefits Renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. Energy for our children’s children’s children Renewable energy will not run out. Ever. Other sources of energy are finite and will some day be depleted. Jobs and the Economy Most renewable energy investments are spent on materials and workmanship to build and maintain the facilities, rather than on costly energy imports.

Renewable energy investments are usually spent within the United States, frequently in the same state, and often in the same town. This means your energy dollars stay home to create jobs and fuel local economies, rather than going overseas. Meanwhile, renewable energy technologies developed and built in the United States are being sold overseas, providing a boost to the U.S. trade deficit. Energy Security

After the oil supply disruptions of the early 1970s, our nation has increased its dependence on foreign oil supplies instead of decreasing it. This increased dependence impacts more than just our national energy policy.

Is it important to create micro energy system or macro system? An energy system may be thought of as an interrelated network of energy sources and stores of energy, connected by transmission and distribution of that energy to where it is needed. The transformation from stores of energy in food to work, and subsequent dissipation of energy is an example of such a system. The starting point of all energy in this “food chain” or “energy chain” (considering only the vegetable and cereal part of our food) is the sun.

Environmental protection

Our earth is our home, so if we want to protect our home we should protect our environment from harmful effects of human activity. Some of these activities cause pollution. Pollution now is a very important problem. Some of these problem are : the ozone holes, global warming ( or green-house effect), acid rain … The ozone layer is a layer of gases which stop harmful radiation from the sun protecting the earth. Recent research shows that there is a hole in part of the ozone layer which is caused by smoke from factories, car exhaust fumes, aerosol cans ’cause they contain CFC. Global warming is an increase in world temperature caused by an increase in carbon dioxide. Acid rain is rain that contains dangerous chemicals, this is caused by smoke from factories. Another problem is poisons in food. Farmer soften spray chemicals in crops to safe them from pests. These chemicals are called pesticides.

Scientists have found that pesticides often end up in our food and they can cause health problems – especially for kids. The seas are in danger. They are filled with poison : industrial, chemical, nuclear waste. Every ten minutes one kind of animal, plant or insect dies out for ever. And if nothing is done our earth will die in about 30 years from now. So what can we do to protect our environment ? I think that we should recycle our used things, we should plant more trees, we should not waste resources but try save them, we also must make smoke from factories and car’s fumes more clean, we must not dump industrial waste to seas and rivers …Now people are beginning to realize that environmental problems are not somebody else’s. They make different organization, whose aim is conservation. For example ” GREEN PEACE ” , ” FRIEND OF THE EARTH ” and others. Everyday millions people from all over the world do everything to protect our environment , and they need for our help. I think we ought to help them , just to make our future better.

Environmental Protection

Environmental protection is an increasingly pressing issue all over the world. Ozone depletion, green house effect, global climate changes or global warming, etc, are the main issues in environment. Recent years, many countries and various organizations have paid more attention into environmental protection. A treaty about global environmental protection was discussed by 192 nations in Copenhagen in December 2011. But I fell every individual on this earth should make sacrifices to prevent environment changes. Yes it is the need of the hour. We should protect the world for the future generations. Why? It is because of mans greed he has the once beahtiful earth into a rubbish of Earth.

He has increased his numbers to terrible proportions, has caused the death of hundreds of species of animals, has robbed and destroyed the planet in his search for fuels; now he stands, like a violent, spoilt child, delighted at the speed of his rise to power, It is he who is on the edge of the final mass destruction and of killing all the life which exists in the solar system. The Earth is our home but much of it is dirty and dying. Rapid industrial development caused a lot of ecological problems. They are: air pollution, water pollution, growth of population and shortage of mineral resources. Air becomes polluted with Cars, trucks, buses, airplanes, factories and plants send burnt gases into the air. The production of electricity causes not only air pollution but acid rains and global warming. Because of acid rains the Earth losses twenty million acres of tropical rainforests every year. This means the extinction of thousands of species that live there, for example tigers. Only 67 thousand tigers remain. Tigers are hunted and killed for their body parts.

Ozone layer is destroyed too and the dangerous rays get through the atmosphere causing skin cancer and other diseases. Most of the air pollutants directly affect the respiratory and cardiovascular systems Nitrogen dioxide and ozone also effect the respiratory system, irritate the eyes, nose and throat and headaches. Carbon monoxide is able to displace oxygen in the blood which in turn can result in cardiovascular and neurological effects. Lead affects bone narrow, impairs liver and kidney function, causes neurological damage and also causes mental retardation in children. Oceans are vital for the life on Earth. We need to protect it. They provide homes for millions of plants and animals, provide people with food and help regulate the climate. But now they are a big dumping ground for tons of toxic waste. Most big cities pour their waste into seas and rivers.

Water pollution is due to mixture of dirt, sewage and industrial waste , increased use of fertilizers and insecticides that seep through the earth and pollute the ground water As a result, there are numerous health problems like dysentery, cholera and paratyphoid fever. Noise pollution is yet another problem that the researchers say causes ulcers, abortions, cardiovascular diseases and hypertension besides several mental disorders. Checking of environmental pollution has been absolutely necessary. if it is not checked, the earth will become a graveyard. So we must give due attention to protect it from our own abuses. We must have balanced and planned industrial growth in order to check thin pollution.

Towns and cities should be planned very carefully and stress should be given on planting of more trees. I would like to dwell on practical measures which must be taken in order to improve the ecological situation: -the factories must be removed from cities; -have balanced and planned industrial growth -purifying systems for cleaning and trapping harmful substances must be widely used; -green zones must be created by planting more trees. -almost everything is recyclable today – recycling is a great way to reduce waste.

We need clean air to breathe and pure water to drink. So we have to prevent disposal of toxic waste and nuclear tests. I feel formal education programmed should be provided and implemented for the environ­mental protection We need to conserve resources like water by planting rain water harvest in our houses Earth is the only planet endowed with a beautiful environment for man to live We should pass it on to our future generation as their legacy. Protect our earth today for our children tomorrow.
