GLOBAL ENVIRONMENTAL ISSUES OF CONCERN TO THE CONSTRUCTION INDUSTRY With the continuously progressing development in the world, environmental issuesare gaining more and more attention of the world. Increasing industrialization has introduced many such problems, which were not faced by our planet before. These include global warming, deforestation, depletion of the ozone layer, acid rain etc. Construction work is a must for the developing nations of the world. But this construction plays a role in increasing the pollution. If proper disposal of the construction waste is not done, it can slowly lead to hazardous effects.
According to a calculation, in Seattle for example, the construction and demolition waste accounts for about 40% of all the municipal waste. But much of this waste can be recycled and brought to be used again. (1)
Construction work can affect the environment in a number of ways. Site excavation, clearance, construction and renovation activities, toxic chemicals, wastes including bricks, cement, concrete, plaster, insulation, metal, wood and wood products; these all play a part in causing damage to the environment in one or the other way. According to an estimate, these wastes comprise of about 15 to 30% of all the wastes disposed of in landfills. Although many governments have passed the laws to restrict the disposal of toxic construction products into the lands, and to recycle the materials used.
Construction industry is now facing big challenges in order to precede their work in an environment friendly manner. Till now, deforestation in the form of ruthless cuttings of the forest trees and the clearance of vast grass lands, has led to increase the global warming effect. We all know that the trees act as the lungs of the earth. Deforestation leads to a loss of wild habitat and the native plant life. The use of heavy machinery leads to the erosion and sedimentation of the ground. Different chemicals lead to the contamination of soil, the surfaces and the ground water. (2)
There is a variety of different sorts of materials used for the construction purposes including, cement, wood, bricks, paints, ceramic, marble, steel, concrete etc. Most of the environmental hazards due to the construction industry occur as a result of the improper disposal of the waste materials produced as a result of construction work. These wastes lead to the contamination of the soil as well as water in which they are disposed. Starting from the step of clearing a land for a construction purpose, a chain of harmful events begins. Deforestation and clearing of the land leads to the damage to the natural habitat living there, both the animals and plants. Many species of animals have now become endangered due to the continuous loss of their natural habitats, and thus reducing their chances of survival.
Deforestation also leads to a warming up of the globe. Different gases and pollutants produced as a result of industrialization and automobiles need the trees to properly clear them. In the absence of tree, these gases continue to accumulate in our atmosphere, and thus leading to the greenhouse effect and global warming. Deposition of different chemicals in the environment has led to such problems like acid rains and smog (smoke and fog). The harmful smoke from the industries, have already led to the damage to the ozone layer.
Many countries have now passed the rules to control such harmful effects resulting from the industrialization and construction works. Stress is being made on using such material which can be recycled to be used again, instead of going as a waste material. Such material is encouraged which uses minimal amount of the package material. There is need for the proper storage of the construction material so as to reduce the amount of waste produces as a result of the damage or exposure to the elements.(2)
Another view is to use such material for construction purposes, that does not need to be replaced so often, so that there is less amount of the construction waste generated overtime.
To reduce the spoilage of the unused material, only the required amount of the toxic materials be purchased, as for examples the paints.
Transportation of the construction materials to far off countries also leads to the generation of pollution. This can be reduced by encouraging the production of the construction materials in the same environment where the construction is going to take place, if possible.
Using the recyclable material is also greatly encouraged. This reduces the amount of the waste production to minimal. The construction material left over at the end of a particular project, should be reused in some other construction project, rather than being disposed of.
Even such material as cabinets, doors, windows, plumbing and lighting fixtures should be tried to be used in some other construction project.
If any land is cleared for the purpose of construction, the cut down trees should be sold, or used for some other purpose. (2)
It is still not very difficult to control the environmental hazards produced by the construction work. By following the rules made by governments in an effort to control the pollution, and by proper planning well before the commencement of construction, we can reduce the environmental hazards to our planet.

...?Economic and Environmental evaluation A comparison of the economic calculation between the Water Treatment Plant and the Combined Heat and Power Plant depict the total expenditure over their life time as ?5,101,392.526 m and ?5,712,050 m respectively. These figures are calculated by assuming 6 percent interest for both the options. A pure economic perspective suggests the Water Treatment Plant as a better option owing to the comparatively less expenditure. But a combined environmental and economic evaluation provides a different result. The benefits from the Combined Heat and Power like the production of clean energy, saving considerable amount of power and reduced carbon emissions are of high environmental value. One of the main...

...which is dramatically high. In order to make these changes, we need to realize the impact of the problem and to come up with ways to address it. We need to look beyond fossil fuels because not all our efforts may work and we need to come up with successful alternatives the soonest possible time. Dimming the sun Through the slide show, I learned that both natural and man-made disasters have caused environmental impact and changes to our climate; but man-made disasters have been more numerous than natural disasters and they have had much more impact on our environment. Man-made activities have often caused heavy particles in the air which have caused blockage of the sun’s brightness. More than blocking the sun, these...

...to the changes in ocean variability i.e. temperature, salinity, current flow (Kininmonth 2004). Problems in Assessing Human Contributory Factors Despite the many climate forcing variables that could contribute to climate change, it is the human influence over the environment that is the greatest force of all. Human’s contribution to greenhouse gasses, particularly carbon dioxide emission have steadily increased since 1800, that produces a layer of thermal blanket in the atmosphere. This in turn has greater impact on the oceans—making them more acidic (Copp & Johnson 2004). Human’s contribution to greenhouse gasses, particularly carbon dioxide far exceeds those of any volcanic activity. Primary causes for carbon dioxide...

...Due Considering Climate Change People who live in a certain place long enough notice when weather patterns are so different than they once were. The summers they experience are not as hot and the winters are not so cold; or not cold at all. It is continuous, persistent changes that are neither subsiding nor returning to remembered “norms.” But, what could cause that? Climate change, an occurrence beginning to happen all over the world, is much more than change in weather, but a transition from one specific ecosystems typical year-round, functioning environment into another.("What is Climate Change?") These changes could permanently alter these ecosystems in ways that are foolish to ignore. In order to understand the...

...The recent history of eroding our natural resources and devastating our environment has led us to the edge of a national disaster. Our unchecked development has scarred the landscape leaving little more than wreckage in its wake. The air we breathe is being poisoned as we ease standards of pollution in a misguided attempt to jump-start the economy. Our water supply, food supply, and rivers are all falling victim to our overzealous need for speed and greed. Even the farthest points on the planet are not immune. Business has lobbied to roll back the current environmental laws and it is time for business to take responsibility and be held financially liable for the destruction of an environment that belongs...

... no. Environmental Studies, Lab Report: Soil Experiment Introduction Soil is usually a vital component in agriculture and determining the nature of the soil is fundamental in understanding or determining the amount contaminant and nutrient content. Therefore, soil test analysis is usually vital in determining the composition of the soil under analysis. Some of the vital components that are usually analyzed include pH levels or acidity, color, and texture. Notably, other analysts usually extent their analysis to the components including water retention levels, organic composition, and soil structure among other elements (Kelling 4). Nonetheless, the soil experiment in this essay aimed at analyzing or testing two different types... no....

... January 16, Boxes as Prisons and Assumptions I believe that it would be challenging for many people to link the nine dots with four straight lines without lifting the pen because they have difficulty in creatively thinking about their options. The box becomes some sort of a prison for them that they feel they cannot escape, which gives limitations to their ideas on solving this assignment. As a result, they keep on trying inside the box only. Also, many people are used to assuming what is right and wrong. They may be assuming that, to solve the problem, they have to maintain the cleanliness of being inside the box. Because of this, their mind will not even consider going out of it. Their assumption is their prison too. Thus... January 16,...

...Environmental studies Comparison of Uranium versus Thorium Nuclear reactors Thorium is a more abundant nuclear power as compared to uranium, which is not so plentiful. Besides, the cost of thorium is significantly cheaper than uranium because of its abundance. This makes thorium a better product in terms of effectiveness in production and minimization of manufacturing costs. The amount used in the extraction of thorium is considerably less than that of the mining of uranium in terms of energy. In the main, this is because its concentration per unit is greater than most of the other compounds. Thorium is safer than uranium in diverse means. In terms of the environment, thorium is a better product in contrast to uranium....
