Metallic mining is a vital part of today’s civilization, where so many components of our everyday life put high demands on the natural resources. At current demand and consumption rates the sustainability of metallic minerals is unknown. The article “Assessing the long run availability of copper” and its response “On the sustainability of metal supplies” gives insight to matters that we as a society will be facing in the near future.
Tilton and Lagos make note that an increase in population at the current demand will inevitably lead to scarcity. In contrary, the opportunity-cost paradigm that is made apparent in the article states that copper could become conceivably less scarce in the future (Tilton, Lagos 2010). By neglecting the fixed-stock paradigm they suggest that the physical quantity of copper does not determine its future abundance Instead they support the notion that a sufficient increase in cost and price will eliminate demands.
Tilton and Lagos state that over the last 130 years there has been minimal fluctuation in the real copper price due to a constant battle between the cost increasing effects of depletion (remote sources, lower quality ore etc.) and cost reducing innovative technology, due to them more or less offsetting each other. This has allowed for high consumption and rapid depletion of copper minerals however as Tilton and Lagos point out that this favorable trend will not continue.
In response to Tilton and Lagos’s theories, the article “On the sustainability of metal supplies” investigates limits and possible trends rather then predictions. The author’s main point for argument is that sufficiency will eventually replace the economic norm. The article opposes Tilton...

- I. INTRODUCTION The concept of Sustainability Development started in the 80’s era and different meaning and definition were introduced. One among them most frequently quoted definition is from the Brundtland Report: "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains two key concepts within it: First, the concept of needs, in particular the essential needs of the world's poor, to which overriding priority should be given; and Second, the idea of limitations imposed by the state of technology and social organization on the environment's ability to meet present and future n...

- Mountaintop mining has been practiced in the United States since the 1960s, primarily in the Appalachian Mountains. The process involves removing all tress from the site, then the topsoil, and then using explosives to remove the remaining soil and rock to reveal coal. The coal is removed and processed, and then the mountaintop is “reclaimed” with soil or an appropriate substitute, and sometimes replanted.6 While mountaintop mining in the Appalachians is only a small percentage of coal produced by the United States, the issues surrounding it are complex and wide-ranging....

- Today, coal powers over half of the electricity in the United States (“Razing Appalachia”). Over the course of many years, several different methods of mining coal have been introduced. The most controversial of these methods is surface mining, a form of mining that involves recovering minerals and ores that are very close to the exterior of the land. The two types of surface mining are strip mining and mountaintop removal. In strip mining, the overburden, several layers of dirt and/or rock are removed to reach the ore, mostly coal that is to be mined.... [tags: Mining]

- Appalachia, a vast, beautiful panoply of lush green mountains. At least, most of the thin line of peaks that make up the Appalachian Mountains used to be that way. Currently, the continued spread of a method of coal extraction known as mountaintop removal mining has plagued areas of the eastern United States, mainly including the state of West Virginia. Throughout its increasing stages of implementation, mountaintop removal mining has caused numerous hampering effects, including causing serious harm to nearby residents, and polluting a once-pure environment....

- Early pioneer of ecological substantiality, Herman Daly, proposed a problem of environmental maintenance. He proposed, (1.) renewable resources of harvest should not exceed the rate of regeneration (sustainable yield), (2.) the rates of waste generation from projects should not exceed assimilative capacity of the environment and, (3.) non renewable resources should require comparable development of renewable substitutes for that resource. (Daly, 1990) Despite his insight and projections, human continue to over use natural capital.... [tags: Sustainability, Ecology, Natural environment]

- I used to believe that sustainability meant to take a stand to preserve the earth. Now however, my position on sustainability has dramatically changed. Sustainability is a way of living. As beings on this earth, we are accountable for our ecological impacts, and it is our responsibility to ensure that we are living sustainably. By examining sustainability through the farming and organic agriculture of Herman Mentink, the saving of the whales and it relation to Pete Seeger, my definition of sustainability changed from taking a stand, to a way of living....

- In recent times, the practice of sustainability has heightened due to the overall condition of the world’s environment. The concept of sustainability is said to had found its roots from the Brundtland Report of 1987 (Hagedorn & Lütteken, 1999). The initial concept of sustainability slightly differs from its original motive. Initially, sustainability was established to promote environmental and agricultural awareness and to advise individuals of more efficient ways to save the environment. However, over the progression of years, the concept of sustainability has evolved into a more socio-economic approach (Hagedorn & Lütteken, 1999)....

- Every day, almost every moment, we are making decisions. The decision-making process is extremely important in our life. Since as long as you made a decision, we will contribute most of our capital, time, focus and energy on the direction you selected. We believe that better decision can make life better. Different decision results come from, sometimes, different knowledge set or preferences people have. Before doing this project, we have reached a consensus that knowledge is power. And data mining can give us better knowledge to make better decision.... [tags: Data Mining Project]

- Mining is a necessary component of the world we live in and it has been practiced for thousands of years. The mining industry produces billions of tons of raw product every year. The process of mining is very complicated and involves plenty of physics. Two main components of the mine cycle are: Drilling, and Blasting. Some important factors in mining are the pillars, rock elasticity, and the slope stability of the ground being mined. A basic method for destroying rock is mechanically induced stress, such as drills and erosion jets.... [tags: physics mining miner]
