The world’s worst polluted places are in the developing world. Similar conditions no longer exist in the U.S., Canada, Europe, Japan and Australia today. In wealthier countries, there are sufficient legal, political, cultural and…
These days, more and more people are using their own cars to commute. The increasing number of vehicles in our cities contributes to the high levels of pollution in the air. When faced with taking private cars or public transport, people react in different ways. I will discuss the for and against arguments of using private cars or public transport.…
Pollution is a very tough topic in today’s market and in my personal opinion; Government should intervene for the following reason. Let's take the example of a company that manufactures blue jeans at a factory location on a river. The problem is that, as a byproduct of its manufacturing operations, the factory dumps chemical pollutants into the river. But no single person or entity owns the river water, so there is no one to force the company to stop polluting. Moreover, since cleaning up the river would cost money, the company can sell its paper products more cheaply than if it had to absorb such pollution control costs. As a result, the paper company can further increase its output, responding to the relatively higher demand at its lower prices, leading to more waste and pollution from its factory. By polluting without penalties, the company may also have an unfair advantage over competitors whose paper products do reflect the cost of installing pollution control equipment. This is a classic example of a so called external cost that is not reflected in the price through normal workings of the marketplace. Neither the paper company nor its customers are bearing the actual cost of paper production; instead, a portion of the cost, the pollution factor has been shifted to the people who live or work along the river and those taxpayers who eventually are stuck with the cleanup bill. Like other externalities, pollution often occurs where the ownership of a resource, in this case the river is not held by individuals or private organizations. Public lands and roadsides, for example, are more often littered than the lawns in front of people's homes, because no one person owns these public lands and takes the responsibility for keeping them clean, and prosecuting those who despoil them. Most pollution is, in fact, released into the air, oceans, and rivers precisely because there are no individual owners of those resources who have strong…
Air and water pollution affect the biotic and abiotic environment on a global scale. All pollutants affect individuals in different ways, but mainly affect those with asthma or underlying respiratory conditions. Transportation and energy consumption are the biggest contributors to pollution and global warming. With world population on the rise, carbon dioxide in the atmosphere is also climbing a steep hill. CO2, a primary air pollutant, is the most major concern amongst environmental scientists, since it is the main culprit for ongoing climate change. CO2 is naturally occurring, and used by plants for photosynthesis, but large amounts emitted directly into the atmosphere by means of combustion make it a primary air pollutant that is affecting the natural temperature of our atmosphere, bringing adverse effects with it. Nitrogen oxides are another example of primary air pollutants, involved in the creation of photochemical smog, acid deposition, and ozone depletion. Nitrogen oxides include nitrogen dioxide, nitric and nitrous acid. NO2 is of most concern; it is a highly reactive gas emitted from vehicles and power plants that also affects the respiratory system of sensitive people, such as elderly and children. Compliance with current NO2 standards has ensured the protection of individuals once affected by this highly volatile gas.…

Pollution effects are not confined to the environment. The potential for damage to historical monuments has already been realized. Some damage, such as from wind or rain, is unavoidable. However, pollution contributes additional risk factors that can increase the level of destruction. The effects may be minor, such as a blackening of the surface of monuments due to dust. Other impacts can have permanent consequences.…
Every living thing has an impact on its environment. Therefore a human impact on the environment is inevitable. By simply existing, all species - including ourselves - will imprint their mark on the world around them.…
Pollution is the contamination of air, soil, or water by the discharge of harmful substances. Pollution prevention is the reduction or elimination of pollution at the source (source reduction) instead of at the end-of-the-pipe or stack. Pollution prevention occurs when raw materials, water, energy and other resources are utilized more efficiently, when less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process. By reducing the use and production of hazardous substances, and by operating more efficiently we protect human health, strengthen our economic well-being, and preserve the environment.…
The Earth is entirely surrounded by a blanket of air which is called the earth’s atmosphere. The atmosphere allows human, plants, and all the earth’s creatures big and small to exist. The atmosphere protects the earth and without it the heat from the sun would burn all that is exposed to its rays, and we could be frozen by the low temps at night. Gas, particulate matter, odors that have been introduced into the air by mankind or nature can destroy the natural balance, this is pollution. There are Primary pollutants and Secondary pollutants, which we will be covering in this presentation, when pollutants are introduced to/in the air, it travels very easily and spread as well, since we breathe in air, we cannot avoid these toxins or pollutants.…
... The Environmental Protection Agency, the governmental regulatory agency created in 1970 to manage the enforcement of environmental policy, states its concerns in its letter to the U.S. Army Corps of Engineers in 2009 (EPA). Specifically addressing mines in West Virginia and Kentucky, the EPA expressed concerns over water pollution from strip mining. The rupture of an ash dike at the Tennessee Valley Authority’s Kingston Fossil Plant in Roane County, TN on December 22, 2008 granted credibility to the EPA’s concerns.... [tags: Environment ]…
