Pollution and Human Health

Ecosystem An ecosystem is often defined as an environment or community, where inter-relationships among organisms take place (Vogt 69). In this respect, plants, animals, natural resources and humans interact for mutual benefits. Other elements such as soil, micro-organisms and non-living things are also included as part of a freshwater lake ecosystem.Advertising We will write a custom research paper sample on Pollution and Human Health specifically for you for only $16.05 $11/page Learn More A freshwater localized ecosystem A freshwater localized ecosystem consists of plants and animals of all kinds (Silk Ciruna 29). Some of these animals and plants exist as producers to other living organisms. For example, the conversion of inorganic matter into organic matter takes place in a freshwater lake. However, plants may perform this process through photosynthesis. Animals like fish that lives in a freshwater lake, usually feed on plants. The plants have chemi cal energy obtained from plant as a result of photosynthesis. In this respect, fish and other animals obtain this energy after they consume plants. It is important to note that there are animals or fish that depend on each other for survival. Living things, particularly both animals and plants die and decompose. Upon decomposing, the matter is changed into organic matter. The inorganic matter can also be obtained from waste produced by animals. Basically, the cycle of both living and non-living organism within a freshwater lake is interrelated and continuous. Without interruptions, this ecosystem is an example of a balanced ecosystem. This ecosystem highly depends on non-disruption from human activities. Living organisms in a lake and their inter-connection Biologically, the living organisms in a freshwater lake are referred as biotic elements. The biotic elements depend entirely on each other for survival. For example, fish, amphibians, insects, snails and a variety of water plants live in freshwater lakes (123). The plants provide the fish with food energy. Some carnivorous fish also depend on other small fish for food energy.  The same can be said of amphibians that live off other fish and insects. From this perspective, the living organisms are related through food webs or food chains.  An aspect of symbiotic relationship can also be evidenced in living organisms living in a freshwater lake. An example of such relationship is evidenced when bacteria survive through the legume plants found in the lake. Insects within the lake habitat live off animals and plants without harming them in what is known as commensalism.Advertising Looking for research paper on environmental studies?

Get your first paper with 15% OFF Learn More Human activities According to Silk and Ciruna, some of the activities disrupting a freshwater ecosystem are fishing, hunting and pollution (321). Fishing Fishing in a freshwater lake targets fish. In this respect, fishing without control measures may lead to fish extinction from the habitat (245). Eventually, there is an ecosystem imbalance within the lake. For example, amphibians no longer have a source of food. Eventually, some living organisms that depend on fish as a source of food also die. Hunting Humans hunt amphibians such as crocodiles, alligators and hippopotamus. Humans hunt these animals for food and skin (231). Eventually, some living organisms like fish over-multiply and affect the production of other important organisms such as plants due to over-dependency. Pollution Humans are known of polluting freshwater ecosystems by using pollutants like oil, waste materials and other activities. This is done through dumping of toxic substances into the freshwater (240). Such activities affect the environment and living organism may die from toxic exposure.

One Sheep, Two Sheep, One Fish, Two Fish . . .

One Sheep, Two Sheep, One Fish, Two Fish . . . One Sheep, Two Sheep, One Fish, Two Fish . . . One Sheep, Two Sheep, One Fish, Two Fish . . . By Simon Kewin What do a sheep, a cannon and an aircraft have in common? The answer is that they all usually use the same word whether they are in the singular or the plural. If you have one sheep and then you acquire a second sheep, you now have two sheep, not two sheeps.   Other words exhibit this strange behaviour too, often other sorts of animal. For example, bison, deer, moose, pike and swine all usually use the same word for their singular and their plural. So, strictly speaking, it would be incorrect to refer to several bisons, deers, mooses, pikes or swines.   I say usually because this rather illogical rule is quite commonly broken and more regular plural forms do creep in for some of these words. Its actually quite common for people to refer to cannons for example. The Compact Oxford Dictionary says that the plural of cannon is only usually the same† so that, in fact, cannons is more and more acceptable.   The process has gone further with other words. For both salmon and trout, for example, the OED now says that either form of plural is equally acceptable. You can say three salmon or three salmons, although many people would still find three salmon preferable. Similarly, the Merriam-Webster dictionary lists both deers and pikes as acceptable plural forms. The Compact Oxford Dictionary, meanwhile, still says that the correct plural for the word pike (meaning the type of fish) is pike. But, as if to illustrate how illogical this is, the plural of the word pike when it refers to the weapon is regular : pikes.   This is another area where there will be disagreement among writers. On the one hand, â€Å"two cannon† is strictly correct but, on the other hand, â€Å"two cannons† is now a common usage and one which is, after all, perfectly clear in its meaning.   Footnote : fish and fishes is an interesting case. Both the Oxford and the Merriam-Webster dictionaries say that the plural of fish can be either fish or fishes. In fact, the two plural words are often used to refer to different things. As the Oxford dictionary explains :   The normal plural of fish is fish, as in â€Å"he caught two huge fish†; however the older form fishes is still used when referring to different kinds of fish: â€Å"freshwater fishes of the British Isles†.   So you use fish when referring to more than one fish of the same type and fishes when referring to multiple fish of different types.

In the year 1954, the United States was changing rapidly. President Eisenhower, a Republican, was in the midst of his first term. Eisenhower had just announced to the world that the United States had in fact developed and successfully tested the first hydrogen bomb some two years prior. Mamie Eisenhower christened the Nautilus, which was the first submarine to run on nuclear power.

New fashions were surfacing in both men’s and women’s fashions. Men were wearing Bermuda pants, baggy pants that were cut off at the knee, while women were wearing capris, tight pants that cut off just below the knee. Men were wearing tailored jackets and making a slight move towards the casual dress of today’s workplace. Women were wearing natural shoulders as opposed to the heavily padded ones of the war years.

The influence of cultural disversity on employees workplace performance in transnational corporations in algeria - Essay Example issues are considered to be very important and are expected to be even more important in the near future due to the increasing differences in the Algerian population. Companies should put their focus on diversity and look for ways to become totally inclusive organizations since diversity has got the potential to yield greater productivity and competitive advantages (Shachaf, 2012, P.32) Given the significant transformations in cultural diversity over the past half-century in Algeria, Both the academia and the media have developed more interest in a better understanding of the social and economic impacts of cultural diversity, ethnicity and multiculturalism in organizations (Watson, Kumar & Michaelsen,2013,P.23). There has been enough research to establish facts on how cultural diversity can improve the performance and productivity of the employees as opposed to a homogeneous cultural workforce, thus this research contributes to the existing body knowledge.

The smiling staff spread the fragrance of a hearty "Welcome to Moe's!" when the customer walks in. Therefore Moe's is into hospitality events and not in production and manufacturing I used to tell the boys that customer satisfaction is the key to our success, and believed in positively motivating them to excel in life. Motivation in simplest terms can be defined as a means of providing motives. Motives can act towards making or breaking the work, towards doing a job more efficiently or for distorting the work environment.

Promote Products Essay Example for Free

Promote Products Essay 1. 1 Choose a product or service that could be promoted. Explain how and why you would promote that product or service. Identify at least three types of personnel you could use to help you plan and organise the promotion. What role would they play? How would their skills and experience help you? At work we are currently promoting our GPS products. We have chosen to promote these via direct marketing and by targeting certain business types. I liaised with our sales consultants, who talk to these people on a daily basis, to advise on what language should be used and what information they felt was most relevant to put across. We needed a graphic designer to create and develop ideas for the letters and DL flyers being sent. I also needed to involve juniors in the business to assist with folding letters and stuffing envelopes as we had determined that this would be a cheaper option for the business than using a mail house. 1. 2 Make a list of resources you would need for the promotion and identify where you could get them. Explain any actions you would need to take in order to have the resources ready for promotion. The database we purchased contained 7,000 leads so we then needed to purchase paper, envelops, ink, return stamps and organise postage. Paper, envelopes and labels for return address were all ordered in advance from Staples. Ink was also pre-ordered to ensure we didn’t run out during the print job. We then liaised with Australia Post to determine the best way to post this number of letters. We chose their â€Å"clean mail† option which meant having to mark each envelope with a pre paid stamp before taking to the post office. This stamp was purchased through Australia Post.
