Biomes and Diversity Assignment Example | Topics and Well Written Essays - 250 words

Biomes and Diversity - Assignment Example This big shift with the invention of farm implements and tools enabled Man to vastly increase his food supplies, stabilize food sources, made food production a secure and predictable undertaking and this incidentally also allowed the arable land to support a much higher population density. Increased food availability made the entire human population grow exponentially. It has also put pressure on the other species of plants and animals, as there is a growing competition for the available food, space, and other requirements for life. Ever since Man burst unto the scene, so to speak, a good number of species had become extinct due mainly to Mans prolific activities. It is a dangerous development, as biodiversity is necessary for ensuring survival of the remaining species. There are strong ancestor-descendant links between various species and their biomes, so the main concerns should be both conservation (wise use) and preservation (leaving untouched). The past century saw the extinction of about 100 species of birds, mammals, and amphibians (Hassan & Scholes, 2005, p. 105) but this background (natural) extinction rate is expected to be 10,000 higher in the next two centuries if based on ancient fossil records, current trends, and computer modeling of extinction rates (M iller & Spoolman, 2011, p. 191). The loss in genetic diversity becomes a serious threat to Mankinds survival as well, because of the links that was mentioned earlier. There are still many undocumented species, in addition to those already well known, which can provide ecological, economic, and medicinal benefits to Man. People can help to slow down the extinction rate by avoiding environmental degradation, reducing their carbon footprint, minimize pollution, mitigate climate change, refrain from introducing invasive or harmful species to a biome, prevent over-exploitation of open common

Dq 8-Sheila - Essay Example Thus, a knowledge worker information system is the combination of data, computer hardware and software and processes that the knowledge worker uses to arrive at decisions in the course of their worker. The purpose of this paper is to illustrate the importance of the knowledge worker information system, together with its relevant aspects, in the work of the knowledge worker and to the organization that employs the knowledge worker as a whole. In todays competitive business environment, information is a major success factor for an organization(Brinkley, Fauth, Mahdon, & Theodoropoulou, 2013). For instance, the marketing manager needs information on the plans and actions of their competitors. These have an effect on whether or not a company succeeds. At the same time, the manager must ensure that their information system is secure and cannot be hacked into by rivals. Thus, a good knowledge worker information system must take into consideration the security of the system. Privacy is an important element of a good information system(Petter, DeLone, & McLean, 2013). The users of an information system should not worry about their personal and secret information getting into the wrong hands. This is especially important in the so-called Information Age in which cybercrime is rampant. For instance, a professor who uses Skype to deliver their lectures does not wish to have their personal information leak to their students. A proper information system can deliver useful information when it is needed(Hsu, Chu, Lin, & Lo, 2014). This is crucial because some of the decisions that the knowledge worker makes are urgent yet they far-reaching implications for the organization. For example, a production manager whose organization uses just-in-time delivery of raw materials risks losing a customer if the information system fails to inform the supplier of the need to deliver raw
