Saskia Binder-Tulenko sb47593 12.5.14 Events of the new millennium irreversibly changed the direction of American foreign policy. During the 1990s, Anti-American sentiments burgeoned in the Middle East within growing radical Islamist groups that perceived America as empirical and expansionist after the prolonged US occupation of Muslim holy sites in Saudi Arabia after the end of the first gulf war. The September 11th attack on the Twin Towers, once representative of American military and economic hegemony, symbolized to many a political failure that would change the focus of American national interest for years to come. September 11th catalyzed a major revival in the American public’s concern for domestic national security, which had dropped off following the collapse of the Soviet Union. The attacks, which were the first on American soil since Pearl Harbor, prompted American leaders to respond with swift and ambitious military action. At this time, the public perceived security of American territory against †Å"terrorism†Ã¢â‚¬â€œan intentionally broad and emotionally charged term– as its chief national interest. Following the attack, President Bush announced the launch of a â€Å"global war on terror†, an international effort to combat terrorist groups and the nations that harbor them–prompting him to establish the Department of Homeland Security later that year. 9/11 catalyzed the public’s support of military presence in the Middle East, as the immediate threat to

Personal Narrative Texas For A Vacation - 1316 Words

â€Å"Welcome to Texas.† That’s what I read as I gazed out the backseat window. My family and I were heading down to Brownsville, Texas for a vacation. Brownsville is an awesome city, not only is it right along the Gulf of Mexico but it’s also right on the border of Texas. As we got off the interstate and into the actual state, I remember looking out the window and thinking how much different — in a good way — Texas was from Illinois. Although we were staying in Brownsville, we would end up spending a lot of time in Port Isabel and South Padre Island, and even going into Mexico. Because of vacations like these ones, I think taking vacations are one of the best ways to take a break but they will never replace a home. When we stopped in Dallas,†¦show more content†¦Port Isabel was the next town we visited — it was also the town we visited the most because it was a town that had a bridge to drive to South Padre Island. On the trip there we dug up a cactus, and although it died, it was still really cool at the time Once we reached Port Isabel I was able to tour a lighthouse for the first time which was amazing. After that, we went to a restaurant named â€Å"Pirate’s Landing,† which was one of my favorite restaurants at the time because they gave kids cardboard pirate hats to wear every time, and it also happened to be on the coast of an estuary of the Gulf of Mexico. When we headed back to the condo, we decided to play some golf since it there was a course not even a mile from the condo. The next day we made the 20 mile trip back to Port Isabel where we went to a local fishing store, where we picked up some fishing rods and bait. Then, we went to coast and went fishing; when it began to rain, we decided to pack up and go back to the condo. Once the storming subsided we made the trip back to Port Isabel, but this time we went over the bridge that connected Port Isabel to South Padre Island. South Padre Island is a town on a barrier island surrounded by the Gulf of Mexico. We ended up spending several days here; only going back to Brownsville to sleep in the condo. The first activity I did while on South Padre was to swim in the Gulf of Mexico. Next we wentShow MoreRelatedSemester A Unit 3 Lesson 31626 Words   |  7 Pagesdifferent classes.

Roman Culture And The Roman Empire - 774 Words

Roman Culture The Roman Empire is among the greater ancient civilizations known to man. In 753 B.C. Rome at one point consisted of The Rhine River to Egypt and from Asia Minor to Britain accumulating some 2 millions square miles. This essay goes over some of their culture and the great strides made throughout 753 BC to 27 BC and from 64 AD to 1453 A.D. I. Military The Roman military focused on teamwork and making their soldiers brave throughout their training. The Equitatus played a major role in legionary tactics. The Romans military was far more superior and successful than any other army for a thousand years. Over many centuries the Romans dominated the world which brought most of Europe, northern Africa, and the Middle East under their rule. The only way to obtain citizenship was to serve in the Roman military and basically get what we call an honorable discharge nowadays. The Army didn’t allow marriage until Cladius came to power in 10 B.C. The military frowned upon being married even after Cladius. Roman tactics and advanced weaponry was extremely influential to their success. They had tremendously brutal heavy cavalry called Franks and Lombards. They also came out with a genius design of an advanced cross bow that was far more accurate than that of an average archer. II.

Ecological Economics free essay sample

Ecological economics ? Wikipedia, the free encyclopedia Ecological economics From Wikipedia, the free encyclopedia Ecological economics is a transdisciplinary field of academic research that aims to address the interdependence and coevolution of human economies and natural ecosystems over time and space. [1] It is distinguished from environmental economics, which is the mainstream economic analysis of the environment, by its treatment of the economy as a subsystem of the ecosystem and its emphasis upon preserving natural capital. One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing strong sustainability and rejecting the proposition that natural capital can be substituted by human-made capital. [3] Ecological economics was founded in the works of Kenneth E. Boulding, Nicholas Georgescu-Roegen, Herman Daly, Robert Costanza, and others. The related field of green economics is, in general, a more politically applied form of the subject. [4][5] According to ecological economist Malte Faber, ecological economics is defined by its focus on nature, justice, and time. Issues of intergenerational equity, irreversibility of environmental change, uncertainty of long-term outcomes, and sustainable development guide ecological economic analysis and valuation. [6] Ecological economists have questioned fundamental mainstream economic approaches such as cost-benefit analysis, and the separability of economic values from scientific research, contending that economics is unavoidably normative rather than positive (empirical). Positional analysis, which attempts to incorporate time and justice issues, is proposed as an alternative. [8][9] The three nested systems of sustainability the economy wholly contained by society, wholly contained by the biophysical environment. Clickable. Ecological economics includes the study of the metabolism of society, that is, the study of the flows of energy and materials that enter and exit the economic system. This subfield may also be referred to as biophysical economics, bioeconomics, and has links with the applied science of industrial symbiosis. Ecological economics is based on a conceptual model of the economy connected to, and sustained by, a flow of energy, materials, and ecosystem services. [citation needed] Analysts from a variety of disciplines have conducted research on the economy-environment relationship, with concern for energy and material flows and sustainability, environmental quality, and economic development.

Once consumed, natural inputs pass out of the economy as pollution and waste. The potential of an environment to provide services and materials is en.  wikipedia. org/wiki/Ecological_economics 1/9 15/09/12 Ecological economics ? Wikipedia, the free encyclopedia referred to as an environments source function, and this function is depleted as resources are consumed or pollution contaminates the resources. The sink function describes an environments ability to absorb and render harmless waste and pollution: when waste output exceeds the limit of the sink function, long-term damage occurs. [10]:8 Some persistent pollutants, such as some organic pollutants and nuclear waste are absorbed very slowly or not at all; ecological economists emphasize minimizing cumulative pollutants. Pollutants affect human health and the health of the climate. The economic value of natural capital and ecosystem services is accepted by mainstream environmental economics, but is emphasized as especially important in ecological economics. Ecological economists may begin by estimating how to maintain a stable environment before assessing the cost in dollar terms. [10]:9 Ecological economist Robert Costanza led an attempted valuation of the global ecosystem in 1997. Initially published in Nature, the article concluded on $33 trillion with a range from $16 trillion to $54 trillion (in 1997, total global GDP was $27 trillion). Half of the value went to nutrient cycling. The open oceans, continental shelves, and estuaries had the highest total value, and the highest per-hectare values went to estuaries, swamps/floodplains, and seagrass/algae beds. The work was criticized by articles in Ecological Economics Volume 25, Issue 1, but the critics acknowledged the positive potential for economic valuation of the global ecosystem. [10]:129 Environmental Scientist sampling water. The Earths carrying capacity is a central issue in ecological economics. Early economists such as Thomas Malthus pointed out the finite carrying capacity of the earth, which was also central to the MIT study Limits to Growth. Diminishing returns suggest that productivity increases will slow if major technological progress is not made. Food production may become a problem, as erosion, an impending water crisis, and soil salinity (from irrigation) reduce the productivity of agriculture. Ecological economists argue that industrial agriculture, which exacerbates these problems, is not sustainable agriculture, and are generally inclined favorably to organic farming, which also reduces the output of carbon. Global wild fisheries are believed to have peaked and begun a decline, with valuable habitat such as estuaries in critical condition. [10]:28 The aquaculture or farming of piscivorous fish, like salmon, does not help solve the problem because they need to be fed products from other fish. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them. [12][13] Since animals are higher on the trophic level, they are less efficient sources of food energy. Reduced consumption of meat would reduce the demand for food, but as nations develop, they tend to adopt high-meat diets similar to that of the United States. Genetically modified food (GMF) a conventional solution to the problem, presents numerous problems – Bt corn produces its own Bacillus thuringiensis, but the pest resistance is believed to be only a matter of time. [10]:31 The overall effect of GMF on yields is contentious, with the USDA and FAO acknowledging that GMFs do not necessarily have higher yields and may even have reduced yields. Global warming is now widely acknowledged as a major issue, with all national scientific academies expressing agreement on the importance of the issue. As the population growth intensifies and energy demand increases, the world faces an energy crisis. Some economists and scientists forecast a global ecological crisis if energy use is not contained – the Stern report is an example. The disagreement has sparked a vigorous debate on issue of discounting and intergenerational equity. GLOBAL GEOCHEMICAL CYCLES CRITICAL FOR LIFE Nitrogen cycle Water cycle Carbon cycle Oxygen cycle Ethics Mainstream economics has attempted to become a value-free hard science, but ecological economists argue that value-free economics is generally not realistic. Ecological economics is more willing to entertain alternative conceptions of utility, efficiency, and cost-benefits such as positional analysis or multi-criteria analysis. Ecological economics is typically viewed as economics for sustainable development,[15] and may have goals similar to green politics. en. wikipedia. org/wiki/Ecological_economics Renewable energy sources Biofuels †¢ Biomass †¢ Geothermal Hydro power †¢ Solar power †¢ Tidal power Wave power †¢ Wind power 2/9 15/09/12 Ecological economics ? Wikipedia, the free encyclopedia Schools of thought Various competing schools of thought exist in the field. Some are close to resource and environmental economics while others are far more heterodox in outlook. An example of the latter is the European Society for Ecological Economics. An example of the former is the Swedish Beijer International Institute of Ecological Economics. Differentiation from mainstream schools In ecological economics, natural capital is added to the typical capital asset analysis of land, labor, and financial capital. Ecological economics uses tools from mathematical economics, but may apply them more closely to the natural world. Whereas mainstream economists tend to be technological optimists, ecological economists are inclined to be technological pessimists. They reason that the natural world has a limited carrying capacity and that its resources may run out. Since destruction of important environmental resources could be practically irreversible and catastrophic, ecological economists are inclined to justify cautionary measures based on the precautionary principle. [16] The most cogent example of how the different theories treat similar assets is tropical rainforest ecosystems, most obviously the Yasuni region of Ecuador. While this area has substantial deposits of bitumen it is also one of the most diverse ecosystems on Earth and some estimates establish it has over 200 undiscovered medical substances  in its genomes most of which would be destroyed by logging the forest or mining the bitumen. Effectively, the instructional capital of the genomes is undervalued by analyses which view the rainforest primarily as a source of wood, oil/tar and perhaps food. Increasingly the carbon credit for leaving the extremely carbon-intensive (dirty) bitumen in the ground is also valued the government of Ecuador set a price of US$350M for an oil le ase with the intent of selling it to someone committed to never exercising it at all and instead preserving the rainforest. History and development Early interest in ecology and economics dates back to the 1960s and the work by Kenneth Boulding and Herman Daly, but the first meetings occurred in the 1980s. It began with a 1982 symposium in Sweden (http://www. ecoeco. org/pdf/costanza. pdf) which was attended by people who would later be instrumental in the field, including Robert Costanza, Herman Daly, Charles Hall, Ann-Mari Jansson, Bruce Hannon, H. T. Odum, and David Pimentel. Most were ecosystem ecologists or mainstream environmental economists, with the exception of Daly. In 1987, Daly and Costanza edited an issue of Ecological Modeling to test the waters. A book entitled Ecological Economics, by Juan Martinez-Alier (http://unjobs. org/authors/juan-martinez-alier) , was published later that year. [17] 1989 saw the foundation of the International Society for Ecological Economics and publication of its journal, Ecological Economics, by Elsevier. Robert Costanza was the first president of the society and first editor of the journal, currently edited by Richard Howarth. European conceptual founders include Nicholas Georgescu-Roegen (1971), K. William Kapp (1950)[18] and Karl Polanyi (1944). [19] Some key concepts of what is now ecological economics are evident in the writings of E.F. Schumacher, whose book Small Is Beautiful – A Study of Economics as if People Mattered (1973) was published just a few years before the first edition of Herman Dalys comprehensive and persuasive Steady-State Economics (1977). [20][21] Other figures include ecologists C. S. Holling, H. T. Odum and Robert Costanza, biologist Gretchen Daily and physicist R obert Ayres. CUNY geography professor David Harvey explicitly added ecological concerns to political economic literature. This parallel development in political economy has been continued by analysts such as sociologist John Bellamy Foster. The antecedents can be traced back to the Romantics of the 19th century as well as some Enlightenment political economists of that era. Concerns over population were expressed by Thomas Malthus, while John Stuart Mill hypothesized that the stationary state of an economy was desirable, anticipating later insights of modern ecological economists, without having had their experience of the social and ecological costs of the dramatic post-World War II industrial expansion. As Martinez-Alier explores in his book the debate on energy in economic systems can also be traced into the 19th century e. g. Nobel prize-winning chemist, Frederick Soddy (1877– 1956). Soddy criticized the prevailing belief of the economy as a perpetual motion machine, capable of generating infinite wealth — a criticism echoed by his intellectual heirs in the now emergent field of ecological economics. [22] The Romanian economist Nicholas Georgescu-Roegen (1906–1994), who was among Dalys teachers at Vanderbilt University, provided ecological economics with a modern conceptual framework based on the material and energy flows of economic production and consumption. His magnum opus, The Entropy Law and the Economic Process (1971), has been highly influential. Articles by Inge Ropke (2004, 2005)[24] and Clive Spash (1999)[25] cover the development and modern history of ecological economics and explain its differentiation from resource and environmental economics, as well as some of the controversy between American and European schools of thought. An article by Robert Costanza, David Stern, Lining He, and Chunbo Ma[26] responded to a call by Mick Common to determine the foundational literature of ecological economics by using citation analysis to examine which books and articles have had the most influence on the development of the field. Topics en. wikipedia. org/wiki/Ecological_economics 3/9 15/09/12 Ecological economics ? Wikipedia, the free encyclopedia Methodology A primary objective of ecological economics (EE) is to ground economic thinking and practice in physical reality, especially in the laws of physics (particularly the laws of thermodynamics) and in knowledge of biological systems. It accepts as a goal the improvement of human well-being through development, and seeks to ensure achievement of this through planning for the sustainable development of ecosystems and societies. Of course the terms development and sustainable development are far from lacking controversy. Richard Norgaard argues traditional economics has hi-jacked the development terminology in his book Development Betrayed. [27] Well-being in ecological economics is also differentiated from welfare as found in mainstream economics and the new welfare economics from the 1930s which informs resource and environmental economics. This entails a limited preference utilitarian conception of value i. e., Nature is valuable to our economies, that is because people will pay for its services such as clean air, clean water, encounters with wilderness, etc. Ecological economics is distinguishable from neoclassical economics primarily by its assertion that the economy is embedded within an environmental system. Ecology deals with the energy and matter transactions of life and the Earth, and the human economy is by definition contained within this system. Ecological economists argue that neoclassical econ omics has ignored the environment, at best considering it to be a subset of the human economy. The neoclassical view ignores much of what the natural sciences have taught us about the contributions of nature to the creation of wealth e. g. , the planetary endowment of scarce matter and energy, along with the complex and biologically diverse ecosystems that provide goods and ecosystem services directly to human communities: micro- and macro-climate regulation, water recycling, water purification, storm water regulation, waste absorption, food and medicine production, pollination, protection from solar and cosmic radiation, the view of a starry night sky, etc. There has then been a move to regard such things as natural capital and ecosystems functions as goods and services. [28][29] However, this is far from uncontroversial within ecology or ecological economics due to the potential for narrowing down values to those found in mainstream economics and the danger of merely regarding Nature as a commodity. This has been referred to as ecologists selling out on Nature. [30] There is then a concern that ecological economics has failed to learn from the extensive literature in environmental ethics about how to structure a plural value system. Allocation of resources Resource and neoclassical economics focus primarily on the efficient allocation of resources, and less on two other fundamental economic problems which are central to ecological economics: distribution (equity) and the scale of the economy relative to the ecosystems upon which it is reliant. [31] Ecological Economics also makes a clear distinction between growth (quantitative increase in economic output) and development (qualitative improvement of the quality of life) while arguing that neoclassical economics confuses the two. Ecological economists point out that, beyond modest levels, increased per-capita consumption (the typical economic measure of standard of living) does not necessarily lead to improvement in human well-being, while this same consumption can have harmful effects on the environment and broader societal well-being. Strong versus weak sustainability Ecological economics challenges the conventional approach towards natural resources, claiming that it undervalues natural capital by considering it as interchangeable with human-made capital—labor and technology. The potential for the substitution of man-made capital for natural capital is an important debate in ecological economics and the economics of sustainability. There is a continuum of views among economists between the strongly neoclassical positions of Robert Solow and Martin Weitzman, at one extreme and the ‘entropy pessimists’, notably Nicholas Georgescu-Roegen and Herman Daly, at the other. [32] Neoclassical economists tend to maintain that man-made capital can, in principle, replace all types of natural capital. This is known as the weak sustainability view, essentially that every technology can be improved upon or replaced by innovation, and that there is a substitute for any and all scarce materials. At the other extreme, the strong sustainability view argues that the stock of natural resources and ecological functions are irreplaceable. From the premises of strong sustainability, it follows that economic policy has a fiduciary  responsibility to the greater ecological world, and that sustainable development must therefore take a different approach to valuing natural resources and ecological functions. Energy economics Main article: Energy economics en. wikipedia. org/wiki/Ecological_economics 4/9 15/09/12 Ecological economics ? Wikipedia, the free encyclopedia A key concept of energy economics is net energy gain, which recognizes that all energy requires energy to produce. To be useful the energy return on energy invested (EROEI) has to be greater than one. The net energy gain from production coal, oil and gas has declined over time as the easiest to produce sources have been most heavily depleted. [33] Ecological economics generally rejects the view of energy economics that growth in the energy supply is related directly to well being, focusing instead on biodiversity and creativity or natural capital and individual capital, in the terminology sometimes adopted to describe these economically. In practice, ecological economics focuses primarily on the key issues of uneconomic growth and quality of life. Ecological economists are inclined to acknowledge that much of what is important in human well-being is not analyzable from a strictly economic standpoint and suggests an interdisciplinary approach combining social and natural sciences as a means to address this. Thermoeconomics is based on the proposition that the role of energy in biological evolution should be defined and understood through the second law of thermodynamics, but also in terms of such economic criteria as productivity, efficiency, and especially the costs and benefits (or profitability) of the various mechanisms for capturing and utilizing available energy to build biomass and do work. [34][35] As a result, thermoeconomics are often discussed in the field of ecological economics, which itself is related to the fields of sustainability and sustainable development. Exergy analysis is performed in the field of industrial ecology to use energy more efficiently. [36] The term exergy, was coined by Zoran Rant in 1956, but the concept was developed by J. Willard Gibbs. In recent decades, utilization of exergy has spread outside of physics and engineering to the fields of industrial ecology, ecological economics, systems ecology, and energetics. Energy accounting and balance Also see:Net energy gain An energy balance can be used to track energy through a system, and is a very useful tool for determining resource use and environmental impacts, using the First and Second laws of thermodynamics, to determine how much energy is needed at each point in a system, and in what form that energy is a cost in various environmental issues. [citation needed] The energy accounting system keeps track of energy in, energy out, and non-useful energy versus work done, and transformations within the system. Scientists have written and speculated on different aspects of energy accounting. [38] Environmental services A study was carried out by Costanza and colleagues[39] to determine the price of the services provided by the environment. This was determined by averaging values obtained from a range of studies conducted in very specific context and then transferring these without regard to that context. Dollar figures were averaged to a per hectare number for different types of ecosystem e. g. wetlands, oceans. A total was then produced which came out at 33 trillion US dollars (1997 values), more than twice the total GDP of the world at the time of the study. This study was criticized by pre-ecological and even some environmental economists for being inconsistent with assumptions of financial capital valuation and ecological economists for being inconsistent with an ecological economics focus on biological and physical indicators. [40] See also ecosystem valuation and price of life. The whole idea of treating ecosystems as goods and services to be valued in monetary terms remains controversial to some.
