Human beings.  Most destructive force on earth - they drain wetlands, flood dry lands, stomp out vegetation with their cattle, cut down whole forests, dump their toxic garbage into streams and rivers and the ground, deplete the sea of fishes  and mammals, fill the air with noxious fumes, etc...they poison the world.

Environment pollution is pollution of water, air, soil, noise, light , visual and radio active .\n\n Pollution is the release of chemical, physical, biological or radioactive contaminants to the environment. Principal forms of pollution include: air , water....\nAir pollution is a broad term applied to any chemical, physical (e.g. particulate matter), or biological agent that modifies the natural characteristics of the atmosphere. The atmosphere is a complex, dynamic natural system that is essential to support life on planet earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the earth's ecosystems.\n\nWorldwide air pollution is responsible for large numbers of deaths and cases of respiratory disease. Setting of air quality standards, such as the U.S. Clean Air Act, has begun to improve air quality for some pollutants. While major stationary sources are often identified with air pollution, the greatest source of emissions are actually mobile sources, principally the automobile. There are many available air pollution control technologies and urban planning strategies available to reduce air pollution; however, worldwide costs of addressing this issue are high. The most immediately available method of improving air quality is adoption of greater use of ethanol fuel (and other bio fuels) and increased reliance upon hybrid vehicle technology.\n\nYou can check out more your self.\nAir pollution :

The earth is protected by the Ozone Layer, which helps us from the sun's damaging uv rays.  As people pollute the air, the ozone layer becomes damaged and evenutally will diminish causing the sun's damaging rays to enter the earth's atmosphere increasing temperatures.  The increase in temperature would cause areas of extremely cold temperature where icebergs are found to become warmer; thus causing icebergs to begin melting.  The increase in temperature will also cause many of the plants that survive and grow in the tropics to die.\n\nAir pollution contribuites to GW by causing the ozone layer to dissapear, leaving sections of "holes" where the powerful ray's of the sun will cause increase in temperatures damaging life forms to include plants, animals that survive on such plants, polar caps melting which could affect the animals (polar bears, penguins, etc).

Erosion\nSoil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. The main agents of soil erosion are wind, water, and tillage. Maintaining a continuous vegetative cover on the soil is usually the best way to control erosion. Soil deterioration and low quality of water due to erosion and run off has often become a severe problem around the world. Many times the problems become so severe that the land can no longer be cultivated and is abandoned. The key to minimizing soil erosion and saving the farm lands is the farmer himself. Ultimately, he is the one who must reduce the level at which erosion sediments are dislodged from his cropland. \n\nStudies in water quality relating to agriculture have shown that, of the four to five billion tons of sediment being deposited in the country's streams each year, over half is coming from croplands. The deposited soil, which contains pesticides, farm chemicals, and nutrients vital to the crops but damaging to ground water, gets there mainly as a result of runoff due to rainstorms and sheet erosion. \n\nRunoff occurs when the rainfall rate exceeds the soil's infiltration capacity. On sloping areas, runoff is a concern since it can carry soil particles, nutrients, and other chemicals with it. \n\nGeological erosion occurs where soil is in its natural environment surrounded by its natural vegetation. This has been taking place naturally for millions of years and has helped create balance in uncultivated soil that enables plant growth. A classical example of the results of geological erosion is the Grand Canyon. \n\nAccelerated erosion can be caused by man's activities, such as agriculture and construction, which alter the natural state of the environment. \n\n\n--------------------------------------------------------------------------------\n\nWind Erosion\nWind erosion, or "soil drifting" is caused by the action of wind on exposed soil, especially smooth, unprotected surfaces. Wind picks up finer soil particles and deposits them downwind. Improper tillage practices, low soil moisture, poor soil cover or any combinations thereof can increase the risk of wind erosion.\n\nDrip irrigation is a successful, economical way to water new windbreaks. \n\nWindbreaks of trees and shrubs in a subdivision in North Dakota make an interesting pattern on the land. \nA living snowfence in Colorado beautifies the landscape and will stop blowing snow, keeping snow on the fields where moisture is needed. \nWind barriers of grass and legume crops are rotated with row crops in Iowa. \nWheat residues are left on the soil surface to protect an Oklahoma crop field. \nBuffer strips of weeping lovegrass protect a cottonfield in Texas. \nPerennial grass barriers protect cucumbers growing in South Carolina. \nA combination of wind barriers and ground cover protects soil. \nWell-managed rangeland protects highly erosive soil in Wyoming. \nThe second most common erosion control practice in Canada is the use of windbreaks or shelterbelts, which are lines of trees or bushes planted at the borders of or within fields, normally at right angles to the prevailing winds (maintaining natural vegetation along fencelines has the same effect). This technique is most commonly used in the Prairies (29 to 37 percent of farms), where the flat terrain, minimal natural brush protection, large fields, and frequency of high winds make cultivated land especially vulnerable to wind erosion. Ontario farms also report substantial use of windbreaks (21 percent of farms).\n\n\n--------------------------------------------------------------------------------\n\nWater Erosion\nWater erosion occurs when rain, spring run-off, or floodwater carry soil particles away. This can occur through sheet erosion, where soil materials are removed relatively uniformly, or rill erosion where flowing water creates sm

Deforestation. When Man gets rid of trees, the  soil can easily be eroded. Also, where there are many trees, as my grandmother used to say, they 'attract' the rain, ergo when deforestation takes place, water catchment areas cease to be that. It's a nasty cycle that just goes on and on until the land becomes completely arid.

What causes erosion to be severe in some areas and minor elsewhere is a combination of many factors, including the amount and intensity of precipitation, the texture of the soil, the gradient of the slope, ground cover (from vegetation, rocks, etc.) and land use. The first factor, rain, is the agent for erosion, but the degree of erosion is governed by other factors.\n\nThe first three factors can remain fairly constant over time. In general, given the same kind of vegetative cover, you expect areas with high-intensity precipitation, sandy or silty soils and steep slopes to be the most erosive. Soils with a greater proportion of clay that receive less intense precipitation and are on gentle slopes tend to erode less. But here, the impact of atmospheric sodium on erodibility of clay should be considered.\n\nThe factor that is most subject to change is the amount and type of ground cover. When fires burn an area or when vegetation is removed as part of timber operations or building a house or a road, the susceptibility of the soil to erosion is greatly increased.\n\nRoads are especially likely to cause increased rates of erosion because, in addition to removing ground cover, they can significantly change drainage patterns. A road that has a lot of rock and one that is "hydrologically invisible" (that gets the water off the road as quickly as possible, mimicking natural drainage patterns) has the best chance of not causing increased erosion.\n\nUnderstandably, many human activities remove vegetation from an area, making the soil easily eroded. Logging and heavy grazing can reduce vegetation enough to increase erosion. Changes in the kind of vegetation in an area can also effect erosion rates. Different kinds of vegetation effect infiltration rates of rain into the soil. Forested areas have higher infiltration rates, so precipitation will result in less surface runoff, which erodes. Instead much of the water will go in subsurface flows, which are generally less erosive. Leaf litter and low shrubs are an important part of the high infiltration rates of forested systems, the removal of which can increase erosion rates. Leaf litter also shelters the soil from the impact of falling raindrops, which is a significant agent of erosion. Vegetation can also change the speed of surface runoff flows, so grasses and shrubs can also be instrumental in this aspect.\n\nOne of the main causes of erosive soil loss in the year 2006 is the result of slash and burn treatment of tropical forests. When the total ground surface is stripped of vegetation and then seared of all living organisms, the upper soils are vulnerable to both wind and water erosion. In a number of regions of the earth, entire sectors of a country have been rendered unproductive. For example, on the Madagascar high central plateau, comprising approximately ten percent of that country's land area, virtually the entire landscape is sterile of vegetation, with gully erosive furrows typically in excess of 50 meters deep and one kilometer wide. Shifting cultivation is a farming system which sometimes incorporates the slash and burn method in some regions of the world.\n\nWhen land is overused by animal activities (including humans), there can be mechanical erosion and also removal of vegetation leading to erosion. In the case of the animal kingdom, this effect would become material primarily with very large animal herds stampeding such as the Blue Wildebeest on the Serengeti plain. Even in this case there are broader material benefits to the ecosystem, such as continuing the survival of grasslands, that are indigenous to this region. This effect may be viewed as anomalous or a problem only when there is a significant imbalance or overpopulation of one species.\n\n Bank erosion started by four wheeler all-terrain vehicles, Yauhanna, South CarolinaIn the case of human use, the effects are also generally linked to overpopulation.

Environmental effects\n\nModern mining companies in many countries are required to follow strict environmental and rehabilitation codes, ensuring the area mined is returned to its original state, or an even better environmental state than before mining took place. Past mining methods have had, and methods used in countries with lax environmental regulations continue to have, devastating environmental and public health effects. The result can be unnaturally high concentrations of some chemical elements over a significantly wider area of surface. Combined with the effects of water and the new 'channels' created for water to travel through, collect in, and contact with these chemicals, a situation is created where mass-scale contamination can occur.\n\nEnvironmental issues can also include erosion, formation of sinkholes, dangerous sites such as deep holes in child friendly communities, destruction of the environment, loss of biodiversity, and contamination of groundwaters by chemicals from the mining process and products.\n\nSome examples of environmental problems associated with mining operations are:\n\nAshio Copper Mine, Ashio, Japan was the site of substantial pollution at end of the nineteenth century \nBerkeley Lake, an abandoned pit mine in Butte, Montana that has filled with water which is now acidic and poisonous. \nScouriotissa, a copper mine in Cyprus that has been abandoned. Contaminated dust blows off this site. \nTar Creek, an abandoned mining area in Picher, Oklahoma that is now an Environmental Protection Agency superfund site. Water in the mine has leaked through into local groundwater, contaminating it with metals such as lead and cadmium. \n\nAlthough such issues have been associated with some mining operations in the past, modern mining practices have improved significantly and are subject to close environmental scrutiny.

There are many effects on the environment depending mostly on where the road is built.  The first effect would be to the wildlife of the area.  When trees and land are cleared for road construction, it results in the loss of habitat for many organisms.  For example, a single oak tree can support thousands of insects and hundreds of birds.  By removing that one tree, you have possible destroyed these organism's habitat.  Also, cutting down trees and clearing land add carbon dioxide to the atmosphere.  Tree and other plants use carbon dioxide in photosynthesis.  They store some in their bodies.  This is released into the atmosphere which can add to the global warming problem.  That along with all the construction equipment letting out carbon monoxide and dioxide during the construction phase.  And that is just the surface of what is caused.

INTRODUCTION\nPollution, contamination of Earth’s environment with materials that interfere with human health, the quality of life, or the natural functioning of ecosystems (living organisms and their physical surroundings). Although some environmental pollution is a result of natural causes such as volcanic eruptions, most is caused by human activities.\n\nThere are two main categories of polluting materials, or pollutants. Biodegradable pollutants are materials, such as sewage, that rapidly decompose by natural processes. These pollutants become a problem when added to the environment faster than they can decompose (see Sewage Disposal). Nondegradable pollutants are materials that either do not decompose or decompose slowly in the natural environment. Once contamination occurs, it is difficult or impossible to remove these pollutants from the environment. \n\nNondegradable compounds such as dichlorodiphenyltrichloroethane (DDT), dioxins, polychlorinated biphenyls (PCBs), and radioactive materials can reach dangerous levels of accumulation as they are passed up the food chain into the bodies of progressively larger animals. For example, molecules of toxic compounds may collect on the surface of aquatic plants without doing much damage to the plants. A small fish that grazes on these plants accumulates a high concentration of the toxin. Larger fish or other carnivores that eat the small fish will accumulate even greater, and possibly life-threatening, concentrations of the compound. This process is known as bioaccumulation.\n\nTYPES OF POLLUTION\nPollution exists in many forms and affects many different aspects of Earth’s environment. Point-source pollution comes from specific, localized, and identifiable sources, such as sewage pipelines or industrial smokestacks. Nonpoint-source pollution comes from dispersed or uncontained sources, such as contaminated water runoff from urban areas or automobile emissions.\n\nThe effects of these pollutants may be immediate or delayed. Primary effects of pollution occur immediately after contamination occurs, such as the death of marine plants and wildlife after an oil spill at sea. Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years. DDT, a nondegradable compound, seldom poisons birds immediately, but gradually accumulates in their bodies. Birds with high concentrations of this pesticide lay thin-shelled eggs that fail to hatch or produce deformed offspring. These secondary effects, publicized by Rachel Carson in her 1962 book, Silent Spring, threatened the survival of species such as the bald eagle and peregrine falcon, and aroused public concern over the hidden effects of nondegradable chemical compounds.\n\nA  Air Pollution \nHuman contamination of Earth’s atmosphere can take many forms and has existed since humans first began to use fire for agriculture, heating, and cooking. During the Industrial Revolution of the 18th and 19th centuries, however, air pollution became a major problem. As early as 1661 British author and founding member of the British Royal Society John Evelyn reported of London in his treatise Fumifugium, “… the weary Traveller, at many Miles distance, sooner smells, than sees the City to which he repairs. This is that pernicious Smoake which fullyes all her Glory, superinducing a sooty Crust or Furr upon all that it lights.…”\n\nUrban air pollution is commonly known as smog. The dark London smog that Evelyn wrote of is generally a smoky mixture of carbon monoxide and organic compounds from incomplete combustion (burning) of fossil fuels such as coal, and sulfur dioxide from impurities in the fuels. As the smog ages and reacts with oxygen, organic and sulfuric acids condense as droplets, increasing the haze. Smog developed into a major health hazard by the 20th century. In 1948, 19 people died and thousands were sickened by smog in the small U.S. steel-mill town of Donora, Pennsylvani
