...Nowadays, Hong Kong pollution has become the city’s hot button issue and it’s something you need to be aware of. Ask the government where do the pollutions come from and they’ll tell you Guangzhou and the factories in the Guangdong area. This is true to an extent, however, it doesn’t really tell the full story. When looking at pollution problems in Hong Kong, it is important to pay attention to vehicular pollution. Hong Kong has the world’s highest traffic density. Gasoline vehicles are major sources of health-damaging pollutants and noise. Besides, the vehicles parts are common wastes found in landfill, and the mishandling of the parts would eventually lead to contamination of water bodies. Thus, in order to prevent further degeneration of our environment and improve our living standard, it is essential to tackle the above pollution problems and change to a more sustainable way of transportation. The green transportation that we would like to introduce here is electric vehicles. Electric vehicles are environmentally friendly: they reduce air pollution, benefit the landfill and provide a quiet environment. as well as coal burning power plants, which contribute an estimated 50% to the total level of pollution. Is the environment of the city similar to the past nowadays? Definitely not! First, Hong Kong has many types of pollution which are affecting our health negatively. The most serious one is the air pollution. If we go to Mongkok, Causeway Bay or even Jordan, we cannot...

...There are two types of the cause of pollution, natural and man-made. Natural pollution occurs naturally and won't cause excessive harm to our lives due to its regeneration ability. While the man-made pollution is caused by human activities, and hard to get rid of. The backbones of man-made pollution are human population and technology. Naturally human needs contact to the environment, we get resources from nature. This is for the sake of living. By the increase of human population, the contact is getting more intensive, because needs are increasing. And by the findings and development of new technologies, human can apply them to get the resources. And it's common that new technologies would bring their respective side effects besides their advantages. Water Pollution Water pollution is any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing that drinks or uses or lives (in) it. When humans drink polluted water it often has serious effects on their health. Water pollution can also make water unsuited for the desired use. Water pollution is usually caused by human activities. Different human sources add to the pollution of water. There are two sorts of sources, point and nonpoint sources. Point sources discharge pollutants at specific locations through pipelines or sewers into the surface water. Nonpoint sources are sources that cannot be traced to a single site of discharge. Examples of point sources...

...free from environmental pollution. It has been becoming more and more serious these days. This makes us think a lot. So what is the cause of this terrible matter? And what is the bad consequence it led to? Let’s try to find out. There’re many kinds of pollution such as air pollution, water pollution... that should be tackled as soon as possible. In Ho Chi Minh City, air tests show that air brings many high risk of health problems for people living here. Dust floats in the air is the top actor that pollutes the air seriously. Many lakes, rivers are getting polluted by the toxic waste from factories as well as daily activities, which has not been treated properly. The results of recent surveys have showed that the amount of heavy metal in soil has been increasing in recent years. Not only that but people also find out that the soil contains a large amount of redundant pesticide in many places. So what is the cause of these current situations? First of all, it’s the lack of common sense of protecting the environment. The bad condition of environment has been due to the poor awareness of many people. Some people think protecting environment is the responsbility of government, not theirs. Others think what they have done is so small that it’s not enough to harm the environment. Another cause of pollution is business’s lack of responsbility. Because of profits, many businesses have offenced the production process, that contributes to cause the pollution. Moreover, the management...

...Pollution in Its Many FormsOne of the most serious problems facing the world today is pollution, that is the contamination of air, land and water by all kinds of chemicals such as poisonous gases, waste materials and insecticides. Pollution has upset the balance of nature, destroyed many forms of wildlife and caused a variety of illnesses. It occurs in every country on Earth but is most prominent in industrial countries.Breathing polluted air is very common to most people, especially those living in cities. In heavily industrialized areas, fumes from car exhausts and thick smoke from factory chimneys can be seen darkening the atmosphere. This would reduce visibility and make the air unpleasant to breathe. Large scale burning of fossil fuels, such as coal, gas and oil, in homes and industries also produces a wide range of pollutants. This includes sulfur dioxide which damages plants, destroys buildings and affects health. Other known pollutants are carbon monoxide, nitrogen dioxide and dirt particles. The fumes produced by car exhausts and factories would normally disperse in the air, but sometimes they are trapped by air layers of different temperatures. The result is a fog-like haze known as smog.The motor car is a major source of pollution. In densely populated cities where there are millions of cars on the roads, the level of carbon monoxide in the air is dangerously high. On windless days, the fumes settle near ground level. Fumes from car exhausts also pour out lead and nitrogen...

...recent years the problem of pollution has become very acute. It is the industrialized west which takes it seriously, because it is suffering from its injurious effects. In India, sufficient attention has not been paid to it so far. If we do not tackle this problem now, future generations will suffer from the harmful effects of pollution. This problem assumes different forms such as Air pollution, Water pollution, Soil pollution, Noise pollution and Paper pollution. All this pollution results from the greed of man for getting more and more money. Trees have been cut down, on an unprecedented scale and large production by industrialization has assumed gigantic proportions. So the main cause of air and water pollution is unbalanced industrial growth and urbanization and deforestation. The owners of industries dump waste material on the surface of the earth or in rivers. So, water is polluted and the waste on the earth produces different poisonous gases which pollute the air. On the other hand, forests where purity air have been cut down and new cities and industries have been established in their place. The cutting of the forests causes what is called "The Green House Effects". It results in the heating of the earth's surface which has serious consequences for life on this planet. As a result, generations to come are likely to suffer from a number of incurable diseases. Timely measures must be taken to prevent the 'Green House Effect'. Paper pollution of public life and morality...

...this era of globalization, pollution has become one of the biggest threats to the wellness of human races. The most common types of pollution include air pollution, water pollution, land pollution, visual pollution as well as noise pollution. All these pollution may be harmful to all living things. Due to the increasing population in today’s world, deforestation has been carried out more frequently to make more land available for housing, industrial purposes, agricultural purposes and others. Thus, these uncontrolled human activities eventually lead to destruction of the environment. For example, toxic waste spillage into the sea, the use of chlorofluorocarbon (CFC), and inconsiderate customers will cause pollution to occur. The main cause of water pollution is the spillage of untreated toxic waste into the sea. This could be unintentionally caused by the leakage of hazardous waste into the ocean while transferring them. Even households generate hazardous waste from items like batteries, used computer equipments and leftover paints or pesticides. However, the main leading factor is the disposal of toxic waste by irresponsible industrial workers or owners. The untreated toxic waste will flow to rivers and then to the ocean contaminating the water. As a result, the aquatic animals and plants will be affected. Humans may suffer skin rashes or intestinal illness coming into contact with the contaminated water. Besides, another contributing factor to pollution is the use of chlorofluorocarbon...

...Environmental Pollution is an international journal that seeks to publish papers that report results from original, novel research that addresses significant environmental pollution issues and problems and contribute new knowledge to science. The editors welcome high quality papers where the pollutants are clearly defined and measured and can be directly related to biological, ecological, and human health effects. This includes air, water, and soil pollution and climate change. New techniques for the study and measurement of pollutants and their effects are also encouraged as well as papers on new types of environmental challenges such as pollution/antibiotic resistances of organisms. Emerging pollutions are of eminent interest, such as microplastics, electronic wastes, light or noise pollution as long as they can clearly be related to the biological effects mentioned above. Papers must be process-orientated and/or hypotheses-based to be considered for population. Papers based on field studies are given priority for publication over micro/meso cosmos studies. Papers, such as meta analyses, that report findings from re-examination and interpretation of existing data are welcome. Modeling papers are welcome only to a certain extent, i.e., they must be related to a specific pollution issue or process that is potentially of ecological and/or human health implications. Critical review papers and commentaries are also of high interest as are letters to the editor. The editors...

...undesirable or unclean elements to the environment causes an imbalance and leads to pollution. This imbalance has not only led to deterioration in the quality of our lives but has also threatened the very survival of all life. If this imbalance grows beyond a certain limit, it may prove fatal. The ever and rapidly increasing pollution is a matter of global concern, because it is not confined to a particular country, region or land. It is a threat to the whole world and must be fought united. The problem of pollution is all the more acute in our overcrowded towns and cities. The ever-growing consumerism has further worsened the problem. The biosphere and ecosystem of cities and towns is fast losing its self-sustaining power. The rapid industrialisation of the cities has made them almost unfit for living. They are full of smoke, noxious fumes, dirt, dust, rubbish, corrosive gases, foul smell and deafening noise. The burning of various fuels in the factories and mills releases of a great amount of sculpture-dioxide in the air cause serious pollution. For example, in Delhi, a large part of the population suffers from respiratory and related disorders. In other metropolitan cities like Mumbai, Kolkata and Chennai, the situation is no better. The thousands of vehicles spewing smoke and producing unbearable noise in Delhi have aggravated the situation manifold. Delhi is symptomatic of the growing urban pollution and chaos in the country. The same fate awaits other cities of the country...

...It includes all living organisms that surround us. ENVIRONMENTAL POLLUTION Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem. Pollution leads to depletion of the ozone layer, global warming and climate change. Pollution can take many forms. The air we breathe, the water we drink, the ground where we grow our food, and even the increasing noise we hear every day—all contribute to health problems and a lower quality of life. TYPES OF POLLUTION WATER POLLUTION NOISE POLLUTION LAND POLLUTION AIR POLLUTION AIR POLLUTION It is defined as the presence in the atmosphere of one or more contaminants in such quality and for such duration as is injurious, or tends to be injurious, to human health or welfare, animal or plant life. Industries, vehicles, increase in the population, and urbanization are some of the major factors responsible for air pollution. Major Air Carbon monoxide (CO) Carbon dioxide (CO2) Chloroflorocarbons (CFC) Ozone Nitrogen oxide (Nox) Sulphur dioxide (SO2) Suspended particulate matter (SPM) EFFECTS OF AIR POLLUTION Air pollution can cause health problems and it can also damage the environment and property.

...Pollution prevention describes activities that reduce the amount of pollution generated by a process, whether it is consumer consumption, driving, or industrial production. Pollution control is a term used in environmental management. It means the control of emissions and effluents into air, water or soil. Without pollution control, the waste products from consumption, heating agriculture, mining, manufacturing, transportation, and other human activities, whether they accumulate or disperse, will degrade the environment. In the hierarchy of controls, pollution prevention and waste minimization are more desirable than pollution controls. In the field of land development, low impact development is a similar technique for the prevention of urban runoff. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution. Air pollution, light pollution, noise pollution, soil contamination, radioactive contamination, thermal pollution, and visual pollution and water pollution. Pollution has been found to be widely in the environment. Research indicates that living in areas of high pollution has serious long term health effects. Living in these areas during childhood and adolescence can lead to diminished mental capacity and an increased risk of brain damage. People of all ages who live in high pollution areas for extended periods place themselves at increased...

...Environment pollution is the mixing of harmful pollutants into the environment causing disturbance to the natural processes and cycles. Various types of environmental pollution are categorized as the water pollution, air pollution, land pollution and noise pollution. Production of solid and liquid wastes on large scale from the industries, emissions of hazardous gases, deforestation, global warming, and many more problems originated by the human beings are the main reasons of increasing the environmental pollution. In the last one decade, there is a great increase in the level of environmental pollution and scenario has become worse than earlier. In the whole universe, there is only one planet named earth provides facility of all basic elements required for the life existence. It gives us life and what we give it, pollution. However, it was much better that if we give it nothing but we give it pollution and contamination regularly. As we all live on this planet, we all are highly responsible for the maintenance of the earth. However, we all forget our responsibility and busy in our daily routine and competitions to just fulfil our needs in anyways. Fresh air and clean water are two most basic needs to sustain life but nothing of both is possible in the modern time. It seems that, after some decades here would be no man, no plants, no animals and no life. All the natural gases in the environment make their balance by reacting each other. Some of them are used as a food by the...

...countries of the world. Often, these countries have extremely poor environmental situations. In many Third World nations, pollution is unrestricted. Countless other environmental problems are also not addressed by the government. Usually, creating and enforcing environmental regulations would be economically disastrous for a poor country. As a result, it is forced to choose between buying food and having a clean environment. Often, rich Western countries take advantage of the dilemma of Third World countries. They dump garbage and hazardous waste in developing countries. First World companies might also build plants, which emit considerable pollution, in Third World nations to avoid the regulations these companies would face at home. Some transnational corporations that produce chemicals deemed overly dangerous in the First World find a market in the Third World. There, governments cannot restrict usage of these chemicals because it would be too costly to citizens trying to make a living. Countries in Latin America, Eastern Europe, Africa, and Asia are the greatest victims of this environmental inequality. In addition to problems created by development and industrialization, poorer nations also suffer environmental difficulties caused by poverty and war, among other causes. Many environmental problems arise in the Third World. Air pollution, water pollution , deforestation, desertification, soil erosion, and poisoning of the environment are among the largest of these. Third World...

...Pollution of the environment in general is an issue in the area that I live in. There seems to be a trend of pollution just in general by the population of people. There are traces of trash, chemicals dumped, waste not properly disposed of, and pollution in the air due to vehicles with improper emissions. Pollution like this can find its way into important resources like water supply, food supply, and the very air the population breathes. In this essay, I'm going to describe the issues of environmental pollution, and the problems that could be tied to them. Pollution of the environment is an issue that is an issue throughout the country. It is one of the greatest challenges to combat due to the fact that it takes the participation of all citizens in order to deal with the issue of environmental pollution. Some people are not even aware that environmental pollution could be the catalyst in many different diseases that some have come across. Unfortunately, what people don't know, they can not take action against because they do not understand the problem. When the subject of the environmental health comes up especially with regards to a small town, one of the main concerns that could come about is the quality of the water if there is pollution. Water is an essential source to all forms of life, so if it is polluted, that means that it has access to contaminate any forms of life. It should be said that the water quality is extremely important to human...

...Sheila Petit-Phar English 101 6th June 2013 Pollution is bad for the environment. There are many reasons why pollution is bad for the environment. Before we mention the different reasons, we will take a look at the different types of pollutions. We have to be aware that pollution has many different forms meaning that pollution can negatively affect the environment from many different aspects. Therefore, the best way to prove that pollution is bad for the environment is to go through each form of pollutions and talk about the negative effects on our environment. According to the Wikipedia water pollution is bad for environment because it leads to the decline of freshwater resources, which means that there isn’t enough safe drinking water to support nearby ecosystems. Animals that drink water filled with different chemicals, and other harmful waste experience poisoning and deaths. The water of rivers and seas is being constantly polluted all over the world by various dangerous chemical and biological wastes. This type of pollution can also create a “Dead Zone” where plants and animals cannot live due to severe lack of the air oxygen. Air pollution is also bad for our environment. Why? Many people may ask. To answer this question I have search yahoo and I find out that air pollution does bigger damage to our greenhouse gases, for instance, not only pollute our planet, but also contribute to global warming and climate...

...Pollution is contamination by a chemical or other agent that renders part of the environment unfit for intended use and deserves emphasis that the environment also refers to the place where you live. Pollution generated by human activities presents the most serious problems to our environment by improper waste management is one of the main causes of environmental pollution and degradation in many cities worldwide, primarily in developing countries and cities here in the United States of America that lack waste regulations and proper disposal facilities that can improve pollution in the environment. Waste can be infectious, toxic and or radioactive, for improper waste management will create a tremendous threat to residents in these under developed cities worldwide, particularly those residents living close to dumpsites. Depending on a city’s level of waste management, waste may be disposed of in an uncontrolled manner, segregated for recycling purposes or simply burnt which can pollute water, food sources, land, air and vegetation. This method of waste disposal creates an environmental degradation and destruction to our ecosystem and poses great risk to our health. Land pollution is characterized by the contamination of Earth's surface, where organisms live. One of the major causes of land pollution is human activities which includes but is not limited to deforestation, littering and unauthorized disposal of industrial waste. Deforestation for the establishment of factories and...
