In the latest Living Planet Report construction and road building was noted as being one of the largest drivers of biodiversity loss due to human activities (WWF, 2008). As global concern about society's impact on the environment rises, the pressure on organisations to work to a higher environmental standard is increasing. With the ever growing awareness and significance of environmental impact the successful implementation of an effective Environmental Management System (EMS) is becoming more...
An acid was once defined as 'a substance that had a sour taste and which reacted with metals such as zinc and iron' Antoine Lavosier, 1780 proposed that 'acids were substances that contained oxygen'. This was disproved soon after as many bases contained oxygen and many acids did not. Humphry Davy, 1815 suggested that 'acids were substances that contained 'replaceable oxygen'', hydrogen that could be replaced by metals. At the time acids were chemicals that when reacting with metals produced...
The work I do is about taking something that could be detrimental and with a few careful steps, having results that make the land beautiful and productive again. Mining really can be a temporary use of the land. What do you think about this statement from a mining management employee? Understanding that mining is only a momentary use of the land is very essential. However, taking to account that the landscape will vary with mining operations is more important. Although, exploration,...
Soil is a natural body comprised of solids (minerals and organic matter), liquid, and gases that occurs on the land surface, occupies space, and is characterized by one or both of the following: horizons, or layers, that are distinguishable from the initial material as a result of additions, losses, transfers, and transformations of energy and matter or the ability to support rooted plants in a natural environment (Soil Taxonomy, USDA) The upper limit of soil is the boundary between soil and...
A lot of studies agree that the earth is covered by over than 70 of water, which that mean we can call the earth as Island. Not all the 70 of water is available or ready to drink, human needs, or manufacture uses. Almost 97.5% of the total amount is salt water, which is representing as the highest amount of water around us. From the previous data, people have only 2.5% of 100% is fresh water. What's more, not all this amount is accusable to use but the 70% of the fresh water is frozen in...
For much of human history, the human population was low; its ability to harvest or extract natural resources and harness energy was within the carrying capacity of the biosphere; and anthropogenic waste, both quantitatively and qualitatively, was within the capacity of ecosystem sinks to absorb. As human population has grown and technology has advanced, consumption of resources and production of waste have vastly exceeded sustainable levels and now threaten to overwhelm ecosystem functions. An...
Sustainable transport or green transport refers to any means of transport with low impact on the environment, and includes non-motorized transport, like walking and cycling, transit oriented development, green vehicles, car sharing, and building or protecting urban transport systems that are fuel-efficient, space-saving and promote healthy lifestyles. Sustainable transport systems make a positive contribution to the environmental, social and economic sustainability of the communities they...
Global Warming is the global rise in temperature since the early 19th century, the immediate effects of global warming are shrinking of the ice caps and rising sea levels, it is also related to climate change as many arid places have now suffered extreme amounts of precipitation and many green areas have started to go brown. Global Warming is a pressing issue at the moment, the human kind and the future of the Earth rely on the decisions we make. So lets find out what are the efforts different...
In the past couple of decades, the world has seen a drastic change in the rise of climate alterations and resource scarcity. This is mainly due to the affects from carbon pollution, greenhouse gases and global warming. The highest concerns with global warming are those of carbon pollution that not only harms the environment but also the ozone layers. Canada is one major example of a country where global warming has affected its climate and its forestry in both positive and negative ways. ...
Using Linear Programming and Sprawl Measures. Land-use planning methodology has changed over the years as the emphasis has shifted from old ways of planning-such as spatially allocating future land uses-to one in which planners utilize digital data and aids of tools (e.g., Geographic Information Systems, spatial statistics, and optimization models) to assist in analysis and better decision-making. Recent advancements in computer technology have greatly improved models and their potential...
