Cause - Effect Assignment - Essay Example However, when they become obsolete and are discarded inappropriately, the products release toxic substances into the environment- including air, water, and soil. Various computers parts have varying levels of toxic substances. For instance, an average computer screen contains five to eight pounds of lead accounting for around 40% of all lead in the US. Generally, these items form part of a larger category of wastes known as electronic waste, or e-waste. Electronic waste generally refers to carelessly discarded, excess, or broken electronic devices. This definition is vague and there is still debate as to whether items such as broken fridges and other household appliances should be included under e-wastes. However, the widely accepted definition includes wastes arising from computer hardware, old electronic devices such as phones (both fixed and mobile) and entertainment gadgets, television sets, computer monitors, refrigerators, and other electronic communication devices. Poor dispos al of e-wastes poses several risks to human health and degrades environmental quality as they contain noxious metallic elements known to cause serious health complications. When the wastes are buried in landfills, toxic constituents can infiltrate into water systems and the soil, and finally reach our bodies. Should we sacrifice ourselves for the sake of technology? There has been a growing call for industry players to effect proper disposal of e-wastes, or to find alternative uses of the wastes, such as recycling and separating the components of the electronic devices for use in various industrial processes. Causes of Increased Volumes of Computer Hardware Although toxins released by poorly discarded computer hardware affect every one of us, the majority is generated by electronic companies and repair shops that do not want to incur additional expenses in adopting sound waste management expenses. Critics also argue that recycling could unintentionally cause damage to the environmen t as it leads to accumulation of electronic materials that will eventually have to be discarded. They further argue that e-wastes do not constitute a significant portion of total wastes. Hence, diversion of more funds to implement waste management practices will only serve to benefit the companies and not the public (Hicks et al, 2005). Besides, recycling of computer hardware exposes workers to the heavy metals present in most of the equipment. This problem can worsen if workers do not wear protective gear. It is costly too since the percentage of the initial cost recovered after recycling can be as low as 1-5%. Using these arguments, companies and individuals have continued to dump computer hardware and other electronic wastes without regard to their long-term effects on the environment. This could subsequently result in the suffering of innocent individuals who have had no input in the disposal process. A second common source of waste computer hardware has been through dismantling shops. Although the recycling process is a noble idea, not computer parts are recycled. The non-recycled parts are poorly disposed leading to increased amounts of waste computer hardware in our town. The steady increase of these computer parts together with other obsolete electronic items could ultimately result into a steady increase in electronic wastes resulting to unmanageable levels.

Architecture of the Greek Culture from the Middle Bronze Age through Research Paper

Architecture of the Greek Culture from the Middle Bronze Age through the Geometric Period - Research Paper Example The paper explores how architecture mirrors the political, trade, and military conditions within Greek culture during the Minoan civilizations, Mycenaean Civilization, and Dark Ages of Greece. The Minoan civilizations (2600-1200 BC) The Minoan civilization represented a Bronze Age civilization that emanated from the island of Crete. The Minoan cities had stone-paved roads shaped from blocks cut with bronze saws (Pedley 36). The Minoan period witnessed numerous trade activities and the construction of striking palaces. An analysis of architecture of this period manifests absence of defensive walls. Minoan architecture features several structures that played the role of commercial, religious, and administrative life. Archeologists have successfully unearthed in Crete a Minoan landscape detailing tombs, palaces, towns, villas, and the roads that linked them. The evidence indicates a thriving prehistoric culture capable of surviving and expanding. The Minoans were prominent sea traders o n the Mediterranean and fostered cultural exchanges with other places such as Egypt. At the height of the Minoan civilization, the Minoan trade increased, in which Minoans came to rule over Mediterranean trading routes. Palaces represent some of the prominent architecture during the Minoan civilization. ... 20). The palaces experienced technological advancement with extensive drainage systems, aqueducts, irrigation, as well as wells that were deep and which were the sources of fresh water that could be used by the inhabitants. The palace buildings had multiple stories, which featured staircases (both interior and exterior), massive columns; light wells, outdoor places where people gathered, storage magazines, which represented the theaters of the ancient times. The method used in the construction included ceramic bricks coupled with stones that used to be rough linked by mortar within the interior walls (Biers 62). The Mycenaean Civilization (1600-100 BC) Greeks initially settled on the Greek mainland close to 2000 BC in which geography played a central role in the formation of a society. Mycenaean were equally wealthy as Minoans on Crete but can be described as relatively warlike. The Mycenaean civilization supplanted the Minoan civilization as the dominant sphere of influence on the G reek Islands. The military activity during the Mycenaean period  yielded to the fortification of major towns  such as Athens. The isolated forts served the purpose of militarily control territory (Pomeroy et al. 30). There were also various forms of exits typified by access ramps, monumental gates, vaulted galleries, and hidden doors fashioned to facilitate escaping in the event of a siege (Pomeroy et al. 31). Fortresses, which were built to suit the prevailing military conditions, represent some of the prominent examples of architecture during the Mycenaean civilization. The fortresses detailed massive walled structure built for defensive purposes. The walls of the structures
