Water

Introduction According to the World Health Organization (WHO), zoonoses are diseases caused by pathogens. Through a natural process, they are transmitted from animals to human beings. With the emerging global issues such as climate change and severe weather conditions, so much has to be done to guarantee environmental safety (Cotruvo, Dufour, Rees, Bartram, Carr, Cliver, Craun, Fayer, Gannon 17).Advertising We will write a custom essay sample on Water-Related Diseases specifically for you for only $16.05 $11/page Learn More Bradley’s Classifications of Water-Related Diseases Bradley gives four main classifications of water-related infections. These include; water-borne infections such as typhoid and cholera, water-washed infections which result from poor personal or domestic cleanliness, water-based infections where part of the pathogens life cycle is in an aquatic environment and finally, infections with water-related insect vectors which are tr ansmitted by insects that breed in water such as mosquitoes (Cotruvo et al. 32-4). The World Health Organization provides two other water-related transmissions. There are those transmitted by inhalation of water aerosols and those passed on by consumption of raw or undercooked contaminated fish (Cotruvo et al. 34). Zoonoses are considered to be water-related for two major reasons. First, part of the pathogen’s life cycle enters water either through feces or urine. Secondly, the pathogen is transmitted from animals to humans through a water-related avenue. This can be either through water ingestion or by contact (Cotruvo et al. 36). One of the factors affecting the distribution of water-borne zoonoses is the presence of contaminated water sources that aid the movement of pathogens from one victim to another. Poor sanitation and disposal of animal and human waste also create healthy breeding grounds for the parasites. Schistosomiasis, also known as bilharzias, is an example of a parasitic disease. Snails, water and humans are the main carriers of the pathogen that causes this disease. Larvae will usually emerge from infected snails that get into water and later penetrate human skin, finally end up in the human host where they mature into adult worms. They mate and the female deposits eggs. The eggs then move to intestines, and later are released either through stool or urine from the human body into water. They then proceed to produce in the water giving birth to what is known as miracidia, a larval form that can smoothly swim about. The miracidia enters a snail host and later comes out as the larvae (Shope 1).Advertising Looking for essay on health medicine? Let's see if we can help you!

A recent occurrence was witnessed in Mberengwa district, Zi mbabwe in March 2010. The outbreak affected quite a number of school going children. The parasites are favored by mid range temperatures of between 25 oC and 28 oC. This is bound to worsen as the effects of climate change continue to seriously bite globally. Human activities are also a menace to the environment and are slowly contributing to the spread of schistosomiasis (Shope 1). Several drinking water companies exist in America to offer quality water services. These companies are required to produce consumer confidence reports on a yearly basis and make them accessible to consumers. The York Water Company is one such company. The company’s 2009 Consumer Confidence Report indicates that the it provides water services to over 180,000 people in 43 communities in York and Adams County, Pennsylvania. Water used by this company comes from a variety of sources that include rivers and lakes. These sources may be contaminated with viruses and bacteria among other contaminants. The company uses nitrate for purification purposes and this can be harmful if not used in the correct amounts (TYWC 2).

Free Essays on War Of The Worlds

â€Å"No one would have believed, in the last years of the nineteenth century, that human affairs were being watched keenly and closely by intelligences greater than man’s and yet as mortal as his own; that as men busied themselves about their affairs they were scrutinized and studied, perhaps almost as a man with a microscope might scrutinize the transient creatures that swarm and multiply in a drop of water.†( from War Of The Worlds) One of the world’s first science fiction novels about life forms on other planets, and an invasion on the human race by alien species, War Of The Worlds was written in retort to many events that happened during the time. One of the most important events was the unification and militarization of Germany. There was an even more specific event that took place before the writing of this novel in which inspired Wells. In 1894 Mars was positioned closely to the earth, which led to much observation. Giovanni Schiaparaelli, an Italian astronomer, reported seeing â€Å"canali† on the planet Mars. Canali meant channels but was mistranslated as canals, which led to much speculation of life form on the red planet. This is just some information on how the novel War of The Worlds was written, now on to what this great piece of literature was about. War Of The Worlds is written as to books in one. Book one is The Coming of the Martians and book two is The Earth Under the Martians. Both takes place in London but before that, it is quoted that the aliens were watching the humans â€Å"keenly and closely† with â€Å"envious eyes†. This leads to the reason of why the aliens are going to try to take over Earth. The alien’s planet, Mars, is dying and their source for living is gone. So in result they plane to invade Earth, not only for living but also to use the human race as food.... Free Essays on War Of The Worlds Free Essays on War Of The Worlds It was this new style of story, that would bring about and create this brand new, exciting and often educational form of literature. It is The War Of The Worlds that really epitomises what science fiction is and what it should be. The enchanting but gruesome tale of Martian invasion became the beginning of the modern science fiction story and was the first ever story about life on other planets attacking the human race (a now very popular theme). Although this exclusive, appreciated and amusing style of writing was graced with instant success in its current form, it too, like any other style of writing changed with the times. Unfortunately the new variation was a change for the worse. The main problem lies within the fairly open and murky definitional criteria. There are no set, distinct guidelines as to what science fiction is and what is not; however most definitions seem to revolve around the idea that science is reality, and how that science effects the reality it is in. It is meant to illustrate the relationship between cause and effect representing a society in chaos, disturbed by the scientific matter, which may or may not be based in fact. This longwinded explanation may seem complex but what it is really saying is that science fiction is meant to illustrate the effect of the improbable (within scientific plausibility) against the setting it is in. It studies the resulting events that did not happen, may have happened, or have not happened yet from a rational perspective, mostly interested in the impact on the people involved. Science fiction is a form of fantastic fiction which exploits the imaginative, and profound perspectives of modern science. I t differs from the fantasy genre to which it is commonly compared as it is meant to respect the limits of scientific possibility. If The War Of The Worlds is indeed the major developer of modern science fiction and the creator of epic science fiction it must therefor...

Argument essay about triffic light camera Example | Topics and Well Written Essays - 500 words

Argument about triffic light camera - Essay Example She argues that these cameras help to record any misbehavior by police officers such as corruption of mistreatment. In addition, Mangu (3) supports the idea that these cameras can aid in security investigations. For instance, in London, camera footage led to speedy identification of July 2005 bombers. Eggers and Tushnet (1) say that a camera is a â€Å"crime fighting tool† to support the idea that security cameras help the police in protecting the public. They dismiss the idea that these cameras interfere with personal privacy on the ground that cameras are used everywhere including in supermarkets and bank ATMs and no one complains about privacy. Richard says that cameras must be â€Å"properly used and monitored† if they have to be effective in fighting crime (1). The implication is that the information from the cameras must be used for the right purpose to protect the privacy of the public. He cautions against abuse of information collected from cameras by the author ities. The three authors seem to agree that security cameras are necessary for public security. Another group of scholars has criticized the use of surveillance cameras arguing that this violates the private rights of the public. Steinhardt (6-7) argues that surveillance cameras gather information that is private to the public and that those who use the information are not necessarily security bodies. Therefore, there is abuse of information collected by the surveillance cameras. He states that â€Å"cops - not cameras - fight crime† to show that the surveillance cameras are unnecessary tools in fighting crime (2). The New York Civil Liberties union (1) says that these cameras collect information that is â€Å"more than required† for fighting crime. This information can be shared, hence exposing the people’s privacy. The suggestion of this group is that the use of cameras be regulated to balance between public privacy rights and safety.
